Damn I was hoping the firmware 2.0 would fix this. I just noticed this issue in some of my film tests I did yesterday. Updated the firmware just after. Was really hoping it would be fixed!
My SONY a7C has exactly the same problem, so does Fuji X-T3/4 it just miracle that Gerald didn't notice it there. Very well done. My Sony ua-cam.com/video/UGeR7POG3dQ/v-deo.html Fuji: ua-cam.com/video/EOIPli9y5Ro/v-deo.html
Panasonic confirmed this issue exists in all their cameras, no exception. Not seeing it only means he didn’t use it in the optimal scenario that shows it. Best of luck
GH6 Owner here: great video, I like how you showcased the problem and explained why it happens, plus showing it on other brands and models, personally I haven't seen that issue in my footage, and I've shot in high DR situations, I was aware of this "issue" before buying my camera but upon getting it and using it In several occasions, I don't feel like it is a big deal to be honest, a lot of cameras with a CMOS sensor have this, it is more pronounce on some but it isn't something that huge IMO, again I can't speak for everyone but as far as my GH6 and my footage, I've haven't experienced it, this might show up in extreme situations, but it hasn't for me. (not defending the camera or anything, it's just my honest opinion)
Yup. Totally agreed. I already made sure it’s very clear that in those specific situations with high contrast such as window setup. Which to me is very limiting to my creative process. I can’t tell my clients:”oh sorry we can’t shoot facing the window because the camera can’t handle it” Again, the GH5 works great. So why are they going backwards now
@@THEDPJOURNEY totally understand, I’ll make some more testings on my own to check if depending on the lens, the streaks are more pronounce or something
@@AndyLSB let me save you time, it's not the lens, that's the first test I did to rule out optical refractions. That's why i said "not suing anamorphic or any lens filters" Again, Panasonic DID acknowledge the problem, they even thanked me for pointing it out. So the problem is there whether you found it or not. You just didn't shoot in the perfect setup that highlights it. Try shooting a candle or a single light source in a dark room in V-Log at ISO 2000
Absolutely facinating. I knew about this problem when I was ar NAB. I took my GH6 out to the Vegas strip for 3 nights shooting everything at 2000 ISO VLog. I shot a couple hundred clips all exposed hard to the right but keeping higlights just a hair under cliping. After pixel peeping those couple hundred clips, I found only one single clip that streaked. It was the white Mirage building in the night sky. Even stranger....of the 10 similar shots framed in a similar manner, 9 of them did not streak. It was only one exact angle and exact exposure that triggered it. All the other Vegas strip street shots were prefectly fine. It's strange how random it is for me. Everything I shot was with in-camera noise reduction pulled back to "0"
As i demonstrated, it all depends on the camera settings and the situation you are shooting in. Keep in mind the more lights you have the more streaks will overlap each other and you might end up having a fully lifted image rather than one light streak because it’s just one light source. In other words, if you just put a vertical light tube along the side of your full image, you will not see the streak simply because the streak is literally covering the full image. Hope that makes sense
@@THEDPJOURNEY I shot about 10 files on the street with the White Mirage building in front of the night sky. It’s weird…one specific angle caused perfect streaking. The next file was just me on the same shot, just 20 feel moved over. That same building, same exposure and same night sky had zero artifacts. Moving down the street several more times and that streaking was still gone. I was expecting to see the exact same problem on each shot because each one was only “slightly” different from each other. But no…only one had the problem. And that one that had it?…had it strongly. It’s so arbitrary. I was expecting to see it in many many shots but no,…it’s like rolling a dice. It just happens out of the blue as a matter of chance? Please keep talking about this. I will do further testing myself on this. Spectacular video that you made on this.
@@clifftotten7609 rolling a dice is a perfect analogy, would you roll the dice when it comes to client work? Try this... go in a dark room, and light a couple candles, set it to V-Log ISO 2000 and see what happens
@@THEDPJOURNEY Agreed....yes this is something that concerns me. I'm taking my GH6 to Yellowstone National park in 2 weeks. I'll be shooting 90% daylight shots in VLog on Eagles, Coyotes and lots of bears. Some evening shots on the Hayden valley wolves. I'm certain this kind of outdoor shooting wont show any problems...but Im curious to see. This is 100% personal work. Please keep invistigating this issue. You are on to a super interesting subject with this!
Thanks so much for bringing this up! I immediately tested my Canon R5 C after watching this, and indeed found that it has the same problem. I brought the camera to a Canon service centre nearby and the technician found that their sample unit also behave the same. She said she would report this issue to Canon HQ, but in the meantime there's nothing she can do to help. I really do hope Canon can somehow mitigate this issue because the R5 C really is not cheap.
Really happy you mentioned that! cuz I've ben hearing about it nut didnt get the chance to test it yet! I was in fact planning to buy it as well, but it seems I might just hold back then
they fixed the problem with software on canon r5 having the same problem. There is also a video on the subject. ua-cam.com/video/dfenxw0OKbc/v-deo.html
After working with this camera for a few weeks, I found a fatal flaw with the footage higher than 60fps. There's a red line though EVERY SINGLE shot. ...and Panasonic won't refund me. They want 2-8 weeks to "fix" it.
just came from your video to check this out! ...what the F man...I was kinda gaining some big respect for this camera despite KNOWING about the AF issues. I recommended this camera to my friend and he almost got it. opted for a blackmagic pocket 4k instead. he'll upgrade to 6k at some point
The issue is not caused the way you have explained it. So let me provide a better one - since I do design cameras. Each sensor has a "optically black" area either on left or both sides of the active picture, shielded from capturing light. As all the pixels of one line are converted simultaneously, next the average of those shielded pixels is subtracted from the active area data. This is called Black Level Correction (BLC) - restoring the black to a digital zero, on each line of the picture individually. The problem occurs when the shielded pixels are locally affected - either by overflowing charge into them from a highlight area, or if a light reflected on specific angle gets under the shield and onto those pixels. Both of this are specific to the design and build of the particular sensor itself. So this then results in artefacts that look like bands, but really its just a grouped FPN issue, as every line may have a different imprecision in black-level correction. PS: I do not know what the DRBOOST is about on technical level.. hate the marketing words without deep explanation. So no idea how that comes into the picture.
Thank you so much for the explanation, it did help me better understand what’s going on under the hood. Of course with that knowledge I would be careful sharing it with other filmmakers, since we are not on that technical level as yours. I was of course just trying to over simplify things, knowing that this will not accurately explain the problem. But as you know it’s just to give an idea rather than go into the science of it. Thanks again for watching and thanks for the clear explanation
Woah,....I'm a bit obsessed with this issue. I just took out my Sony FX6 and shot some SLog-3 and I got a very similar blooming/streaking using an iPad in a dark room. I have the FX6 set with noise reduction set to "low" and it has the SAME GH6 horizontal banding lines. It's VERY interesting. Not only is the FX6 showing grey banding but the noise itself "runs" and dances sideways with the bands. I swear that I have never noticed this before but not that I'm hunting for it, it's showing up. It's kinda crazy. Can any other FX6 owners test this with a "square" light source like an iPad? *Edit - Yup on my second test, I can absolutely confirm the Sony FX6 is doing this too. It seems to be a certain "ratio" between the light vs. shadow. There seems to be a bell-curve "problem" peak point. When closing and opening the aperture, as the blooming increases, the banding will get stronger. It "peaks" at a certain bight to dark ratio and then "fades" as the light gets more intense. Moving the aperture back again will bring the banding back until it peaks and then recedes again. When it peaks, it's pretty strong. Absolutely fascinating...wow. The Sony FX6 has this too!
@@burritobrosvideos8060 - I didnt use an actual iPad. I used a Tripplteck tablet that has 1000 nitts. I placed it in a dark room with full brightness. I had a large black plastic sheet behind it. I shot in SLog-3 and ramped up the gain step by step. I noticed the artifact peaks at a certain white/black "ratio". It's not there in lower ISO's then appears, then fades away as you go up. There seems to be a certain peak bell curve or "sweet spot" that it lives in. If you are below it or above it, it's only minor. When you hit the gain, it appears. It's odd and fascinating. I swear I never noticed this once until I TRIED looking for it. Now? I can spot it. Bizarre!
@@burritobrosvideos8060 - I might do a video on it, yes. However, you believing it is something that is not necessary for me. If you do, I don't care. If you don't, I stiil don't care. It just doesnt matter to me either way. If you have an FX6, you should be able to see it if your light source is sharp and defined enough. I'm pretty sure that if you do it right and you look,...you WILL see it. But hey, it's totally up to you. ;-)
Whoa, that's nuts! I just watched a video of someone comparing the Komodo to the R5c and R5, he's switching to the R5c, and he did a dynamic range comparison between the two. The Canons both had this issue fairly badly and the Komodo didn't seem to have it. I was quite thrilled but I will be testing my Komodo to see if I can spot it. I'm hoping not, but I will be comparing to my S1H.
Yeah I did hear about that on the R5C. Haven’t gotten my hands on it. But it seems this is becoming an issue with new cameras for some reason! Pretty weird!
@@THEDPJOURNEY - No the Canon C300 has this issue too. See Micheal the Maven's documented C300 banding/blooming UA-cam videos. My Sony A6500 had in SLog too.
Hey thanks for this. I am sure it drove down the price of the gh6, which I picked up for 1500 dollars new a few months ago. The 5.7k pro res hq images are terrific. I updated the firmware to 2.1 and have really tried to create your scenarios for streaking. I thought I saw one sort of streak and moved the camera about three inches to the right and it was gone. Then I changed the iso and it was gone. I have shot maybe...200 hours on the gh6...in every lighting condition I can conjure up and--no streaking. I bought the camera thinking this might be a workaround, but now realize it is a non issue, at least for me, and the best friend to those of us who seek maximum image quality at the lowest price possible. I really like the images it produces and look forward to picking it up and shooting every day. I am a former journalist who does not like bs or corporate pitch people, so...my views. I really like your videos. Keep up the good work.
0:19 Been waiting for a full breakdown of this. I found this in two different copies of the GH6 that I bought. I reached out to mft facebook groups and even the Lumix UA-cam channel and all I got were crickets. They still haven't addressed it. That and a couple other let downs with the GH6 led me to finally switch out. Currently happy with my Sony full-frame setup. Much more expensive but it's definitely worth not dealing with the shortcomings of Panasonic. Thank you for this breakdown!
Another GH6 owner here that has never experienced this. I just went back and looked through a bunch of my footage as well, and couldn't find any examples. Very interesting though, I'll certainly be more aware of this in the future. Sucks that a lot of people will swear of the GH6 forever now because of this video, when probably 99% of them would never experience this, because it is an absolutely amazing camera, and I wouldn't trade it for anything (well, not literally, but anything comparable) .
I guess you're lucky none of the scenes you shot expressed that streaking, I assume they're all morning outdoor shots or just high key shots with no lights shining directly into the sensor. But that does not mean it's not there, it's jut you didn't shoot in the settings and that induce it the most. Panasonic did replicate it in all their cameras and they're confirming it's there, no denial there. So your camera has it and one day you'll be able to see it when shooting in similar kind of high DR scene like the one i featured here
@@THEDPJOURNEY I only shoot in extremely high contrast situations. Bars, nightlife, etc. I can't find any examples of this popping up in my photos. Over 20,000 photos over the last couple months, with about 15,000 of those happening in various high contrast situations. Can't find even one example after scrolling through for the last half hour.
@@THEDPJOURNEY So I was finally able to replicate this today. I did find it to be very lens dependent though. Using a vintage OM lens on a speed booster it was almost impossible to get it - DR boost had to be on, and exposure set for the light outside the window, while the inside was quite dark. The native MFT lenses I tried were the most apparent (25 f1.7, and a 12-50mm f3.5) while the two lenses on the metabones were much more difficult to produce it, but also varied a bit (1980's OM 24 f2.8, and a Tokina 20-35 f2.8). I almost always use the metabones adapted glass, so I'm guessing this is why it's taken so long to see this. Also, I don't know that I'd ever shot inside while exposing for what's out the window - and this time was just testing out lens.
Need a sequel on this since it appears to be the same issue present in the new Blackmagic cinema camera 6k FF. Is that maybe the reason you won't review that unit?
@@THEDPJOURNEYcan confirm. It’s way more pronounced on the blackmagic Cinema Camera 6k FF. From my experience it streaks in well lit conditions too( if you’d like I provide some sample footage via email). I’ve had the camera replaced twice and been in contact with blackmagic who provided the same response as Panasonic. Blackmagic told me shooting events is improper use case because it’s a cinema camera so I should be controlling my point of highlight like any cinema camera in a studio set…. Most BS response I’ve ever had with a camera company.
I've been shooting with mine for over a week now in all sorts of scenarios and never once had this issue. Shooting in 5.7K 24p/60p & C4K 120p 420 10bit internal VLog. I've filmed with bright windows as the only light source in a completely unlit room, exteriors, interiors, etc and never noticed this issue. I wonder if it was a limited run of early cameras or a bad batch of sensors? EDIT** I've also been shooting in ISO 400 (Native) or with DRB at ISO 2000 (Native when using VLOG)
You’re lucky then. The issue is there, a Panasonic did recreate the issue in their labs and that was the reason why you heard influencers like Gerald Undone say they got the camera late. Simply because they were working on a fix. Try to recreate the setup I had and let me know what you get
@@burritobrosvideos8060 You're right, I was able to get it to show by setting it up looking out a bright window and then adjusting exposure until interior was completely dark. Not really a real world scenario haha. In real world use, it's never been an issue. Either buy and enjoy, or worry for nothing and miss out.
Great to have you back, Sherif. Such a shame about these streaks. I'm so in tune with my GH5 and GH5S that a GH6 would have been a logical progression for my aging cams at least from a workflow and ergonomics perspective. I'm amazed the GH5 is still ticking after all we've been through together. Where would you go next if my GH5 bites the dust?
@@THEDPJOURNEY Can you explain the rational of S1H MkII over GH6? This is completely fixable in firmware and clearly the camera is either overcompensating or undercompensating. It is a very bad move to release it in that state, but I am sure it will be fixed in few weeks at most.
Since you are so in tune, why not the underestimated GH5 Mark II… Even if you were to go with the GH6, or any other camera, your workflow would be affected. The GH5II, does have a newer processor (which means firmware updatable), and IQ is shaper, as well as better in lower light. Plus the AF is better too, usable, similar to the S5, but with a smaller sensor it probably is even more effective. Most importantly, the GH5II is cost effective, and you would not need to change much if anything at all related to your process… …
@@RagingShrimp67 I'm hoenstly not very optimistic about being so sure they'll fix it. They literally acknowledged the problem when I first reported it Mid January, and it's been 4 months now and they didnt fix it. Not just that, when they launched the camera, they told me they're ok with the problem as is now. So they might not even be trying to fix it. I hope this episode would add some pressure. it's for our benefit after all what I'm doing here.
Using an iPad with a bright white .jpg in a dark room...I was able to force this blooming/streaking artifact....but only partially. Now that I have being testing this and delibretly trying to "force" this blooming, I have noticed that I can only get this problem on shots that were unusable to begin with. I could not get the artifact to to appear on well exposed shots. I could not get the artifact to ruin "good" shots. I could only get the blooming/streaking problem to appear in shots that were already really bad to begin with and were already unusable. Does that make sense?
Absolutely, thing is, “cinematic” filmmaking is all about shooting into the light, which is my fav type of look. With that said, most if not all my shots will be destroyed. I didn’t really spend much time trying to force it, it was pretty easy to come by honestly. Not sure why it was very hard for you to recreate it. In the end, if you feel you’re comfortable with that, then it’s all good. Just keep in mind that there’s always a chance for it to ruin your shot. So be careful
@@THEDPJOURNEY - Agreed. Yes,...this is concerning to me and something that I take seriously. Although, my GH6 is intended for Alaska and Montana hiking. I have a large library of grizzly bears and wolves that I created with my GH5. I dont see this ever being a problem in daylight shooting of wildlife. But yes...this blooming/banding issue still wiil certainly still be in the back of my mind. Keep up the excellent work that you do. Im a big fan of your channel!
The video feed on the monitor and the recorded video are on different circuits. The streak will not look as bad in the footage as it is on the the screen, but it’ll still be there
Wow, man! Thanks for the video! That’s a huge issue, wth, why nobody truly talked about this? It’s a dealbreaker for sure, it’s basically unusable. I would never buy Panasonic anyway because of their braindead position on autofocus, but this just confirmed it for certain: from the leader of the industry in the video mirrorless world they’ve turned into a company that produces subpar products with major flaws. Screw this. It was the reason for me to switch from Canon a long time ago, and now Panasonic is going the same route. Pathetic. But once again, big thanks for this extremely important video!
Thanks for watching! They do have really great cameras, I used them in so many commercial work. The quality is usually awesome. But the AF is of course a major flaw compared to others these days. But I know they're working on it. But this streaking issue, was pretty unexpected. I'm now doubting their QC
The S1 has internal 6k, full frame, 4k 60 fps with a crop, no QC issues, etc. I dont know how you could judge all of Panasonic based on their attempt to push M43 beyond anyone else. The S5 and S1 are incredible quality, and have been supported so well through firmware. What's clear is that a larger sensor simply is king.
@@CanditoTrainingHQ spot on. The S5 is just insane value for money. Saw it was on sale for under $1500USD a week or two ago. 80% of my Sony a7S III capability (and exceeds in some cases) for ⅓ of the price. Agree the S1 is WAY in the shadows of the S1H. You can picked them up used for less than a GH6. Meanwhile I'll continue to deal with my Sony's star eater issue....not like they have had long to fix that...oh wait...only since the gen 1 a7 series. Don't get me started on the Canon Cripple Cam marketing, the R5C is an amazing camera, but let's not pretend like Canon don't speed limit video on their hybrids to protect their cine line. Yes this streaking is an issue, and yes Panasonic's response is disappointing. It makes the GH6 a no go for anyone concerned about IQ, which would be one of the main drivers to upgrade from the GH5x line. One bad issue present in a particular scenario does not mean Panasonic have lost their relevance.
@@CanditoTrainingHQ They are decent cameras, sure, but with garbage AF. And unfortunately Panasonic is doing a “Canon” on us all by refusing to put a decent phase-detect AF there. I don’t like Cripple Hammers, I’ve been using Panasonic camera with shitty unreliable AF for long enough already, I don’t want that anymore in my life.
Panasonic HQ in Japan replicated the problem and as mentioned they do acknowledge its presence in all their cameras, so the problem is there no doubt about it. You were just lucky that you didn't shoot using the settings or scenes that makes it prominent.
@@THEDPJOURNEY I know, this issue is even described in the quick guide out of the box! They say it's a character of the sensor. If you are going to shoot towards a window, you turn on dynamic range boost anyways. Besides, I am a cave photographer and filmmaker. When a headlight shines towards you in the cave, the scene contrast is going to blow any camera off and show any in-perfection in the lens. However, I didn't found the banding an issue. The issue I found (the real issue that nobody talked) is that the GH6 drives focus motor more forcefully than the GH5, thus creating lots of noises that make the in-camera mic unusable.
This problem is pronounced in several camera's...but the Panasonic M43 GH6 is so bad the video is labeled "THE PROBLEM with GH6 and why I didn’t review it" regardless of the stunning video quality and feature set. A little FF bias from DP Journey?
Thanks for the info, very in-depth. I am assuming you tried this in version 1.2 of the camera's firmware before posting all of this? I have never come across that issue but am interested to try and recreate it.
We've been shooting a lot of outdoors with GH6's since it came out, and are very pleased with it... Never noticed this issue, I guess in real world this is a very rare situation, and Panasonic decided to release the gh6 with this issue hoping it won't get noticed by many...
The issue won’t be clear in high key shots, only when you have a dark setup with a strong light source shining against that dark, like almost all indoor room with a window shot, a concert, etc…
At this point in time I somehow get the impression this issue is not a deal breaker for most (97.5%?) owners. But I do get the concern considering the GH6's cost. I am good with it but I am not a professional submitting an entry for an academy award.
Yeah, problem is, being a full time DP, 99% of my shoots are commercial work for clients that will not hire me again if they see such issues with the sensor.I can’t risk putting them or myself in such situation
1 year later, I still love my GH6 and that streaking has happened only in very specific extreme situations when anyways the image would have been crap. So no big issue as this video attempts to make it. This camera is awesome and I still love to use it everyday.
Really happy the streaking is not causing you any issues. It’s a great camera after all, no doubt about it, but me personally, I’d never use it on a commercial set, can’t risk that streaking ruining the client’s shots
@@THEDPJOURNEY It wouldn't because there is probably zero chance you experience it. I think the best situation to test the issue was the total eclipse we had last week. Zero problem. Not seen one sign of it. That's because anyone who can expose well a shot should never run into this very niche issue. I find it a little over the top to talk about "the streaking issue". I've tested mine extensively ever since I've had the camera, in october 2022 and managed to see it once when I was at 25 600 ISO and pushed the exposure to its maximum capacity filming a full moon. Not exactly something I would do if I was filming for a client!
I mean, Panasonic themselves acknowledged this was a problem, and they tried to fix it in many firmware updates till they told me it will never be fully fixed. Calling it an “issue” or a “problem” is quoting the makers of the camera itself, not just my assessment. So again, I’m glad this issue is not affecting your workflow, for me, I’m just waiting for the GH7 All the best
Same here… I shot many other test shots and didn’t feel it when the footage is mainly broght. Only in low key shots where you have sharp contrast like the example demonstrated in the episode.
Conclusion: This is not a problem if you use normal color shots. Gh6 problem is a little disappointing but it's Only visible when you have very bright next to very dark high contrast: (i.e. black and white is the worst example of this), and it is worse if you boost contrast and luts. (all Cmos cameras have a little of this). None of the GH6 images I've seen with normal chroma range shows this problem. In this regard the Gh5. Gh5s and Gh5/2 and Pana's Full frames are still highly usable. And so is the GH6 if you don't use luts and high contrast with as shown here. I suggest another test with full color, (with and without luts) will demonstrate a good outcome The three gentlemen referred to in this clip are all very good in this game , including Gerald ; -)
If you don’t have a high contrast shot with mid to dark areas next to it, or super soft overcast look… then you should be relatively ok. But you never know what situation you’d be in on set…mixed with your camera settings. That’s what scares me, the creative restriction
@@THEDPJOURNEY You cant win that kind of talk with a gh6 fanboy ^^ I see so much comments and hypes about the gh6, but in my world its not a very good cam for cinematography. There are better cams i would buy. I have the S1H and love the cam very much. Thats an amazing image. The only thing i hate with the S1H is that i cant change the shutter speed and the exposure together.. ANd the rolling shutter. But the image quality is absolutely amazing like your fx3 and bmpc
Thanks for pointing this out. But I bet in 99% of uses, it wont be a problem. My Problem is I think Dynamic Range Boost feature is gimmicky for what its worth. I wish it was Dual ISO instead.
Yeah I’m here to point it out and tell you how this will affect my decision in using the camera. I’m not telling people what to do. And yeah, I wish the DRB could go lower than ISO 2000 like dual native iso
@@THEDPJOURNEY This time I used the cmos from non-sony, and used the cmos of sony. This is the reason why Panasonic users thought that the image quality of Panasonic was good. The s1h Mii S5mII is likely to use the cmos of Sony, the noise level and image quality. If so, I will I believe that many users who like clean and pure pictures will be lost.
Well it does function as a dual native iso....the iso performance in low light clearly gains the same advantages seen with a dual iso sensor, and the entire technology that the dynamic range boost is based off of is the presence of 2 separate sets of iso circuitry. It IS a dual native iso sensor, they simply implemented it in a way they felt was more useful. This way you can get both the dynamic range improvement above iso 2000, and the iso improvement. I don't see your problem with it. I can compare it directly to a gh5 a g9, and a bmpcc4k. It trashes them all in high iso tests. Only the gh5s and bmpcc4k are close in performance, but my new gh6 instantly convinced me to sell the bmpcc4k. It's simply unnecessary if you have a gh6. I've never seen the light streaking issue. It's obviously not a problem even in high iso shooting unless you are pushing the image trying to recreate it.
@@Whatsup_Abroad You are right. I did not hear about the Dual ISO at the launch so figured for some reason it did not have it. So that's good! But now the question. GH6 vs S5?
@@chrisklugh If you show up as a videographer to a professional set with an s5, and another guy brought a gh6 and they hired based on cameras every cinematographer I've ever met would choose the guy with the gh6. It's feature set is far beyond the s5. More, higher framerates, better codecs, better video quality, better stills quality for certain types of shots (100mpx high rez handheld is fucking amazing, I got some bananas shots out at a zoo recently even without a zoom on me), faster drive speeds, better af in 60p, timecode, real vlog included in the camera, etc etc etc. The s5 is a low-end enthusiast ff stills camera that serves as a decent video camera. The gh6 is a full on cinema camera with every industry leading feature on the market that also takes ridiculous still life and landscape and posed portraits at 100mpx brought down to a reasonable price by using a smaller sensor. It is FAR superior as a creative tool. The s5 only really makes sense to me if you are using it as a cheap entry to the panasonic ff system and are planning to upgrade soon to something like the s1h and use the s5 as a backup. If you are actually looking for a go anywhere do literally anything camera the gh6 is even a better choice than the s1h. Features Trump the tiny image quality gain you get from full frame IMHO.
Glad to hear you’re happy with the camera, it’s pretty awesome and full of great features. Panasonic did confirm to me directly that this issue exists in all their cameras, not seeing it does not mean that it doesn’t exist in your unit. You’ll eventually see it sometime when all conditions are right to induce it, hope it won’t be on a shoot for a client
@@THEDPJOURNEY thanks for the information, I really did the test and not seeing the problem I thought my unit would not have the problem, I hope they release an update soon to solve this problem. thank you friend!
There was an update on July 11th of 2023. Did this fix the streaking issue? Glenn Fricker from SpectreSoundStudios found what he calls the "Red line of death" in slow motion. Did you also experience the "Red line of death"?
I didn’t test the latest update actually. Since I’m not suing this camera at all because of the streaking, I didn’t see the red line of death LOL But I did hear about it. Panasonic dropped the ball this time on that sensor unfortunately
Thanks so much for making this video. I hope it helps to light a fire under Panasonic's rear end and get them to address the issue. However since they have known about it for over 2 firmwares now, I wonder if this is an unfixable hardware issue with the sensor.
AFAIK the issue is already fixed. Either way we'll wait and see, no one is forcing to buy the camera if it's not good enough for their use case. Also comparing AF to streaking shows very poor technical understanding of the topic.
@@THEDPJOURNEY i own both of the cameras, S5 i’ve bought thanks to your videos and now i can’t decide which is better for me)) I love 6K Pro, but lack of stabilisation is killing me…
Mate I noticed it also while the dude from CIneD was reviewuing it. Everybody does not payes attention to it, they just mention it and goes next, cause it was beta and they never touch that camera again. When I noticed it, I was like wtf? seriously? Anyway, thanks for the content, u r bringing less content, but striking like a lighting :D not coping the specs sheet, thats why you have my follow. :)
@@egran2150 Great artist do not wait for the perfect tool or instrument, they are that tool or instrument, and will make art with whatever is in reach… There is enough footage in the wild with the GH6 or any of the other cameras with similar sensor types, that show it’s not a hindrance. … …
Hey I know this was a controversial video(in so much that it highlighted an issue that upset people) and the drama around the GH6 was massive at the time, could you clarify something you said in this video, you mention that the low iso circuit expressed bad enough streaking you would avoid shooting in these iso's all together. Do you mean in genreal or in these lighting conditions?
OMG! I received my GH6 last week and have not had time to use it, so I was really disturbed by your findings! I decided to set up a series of tests but It failed miserably on the first one so it is going back tomorrow! For anyone wanting a quick test just put an iPad a meter or two away on a table in a slightly dimmed room and the ugliness is there to see as clear as day. There is no denying it! I replaced the GH6 in the test with my GH5 and it was a night and day difference with the GH5 showing slight blooming but minimal smearing. Yes the GH6 had the superior quality of image but it was totally ruined by the smearing so it would be just as unusable in the same circumstances! Truly disappointing! Thank you so much for telling the real truth about that sensor problem. I very much doubt this can be fully fixed with firmware! 😔🙏🏾
@@RagingShrimp67 If you saw what I saw in my test or do your own I think you might change your mind! Fully fixed would be to the same level of what the GH5 copes with in the same tests! ,In my own test they were worlds apart! I hope you are correct because otherwise the camera is awesome, it is so good that I bought all the Olympus 1.2 primes last week to go with it!
@@EugeneMaynard There are 2 scenarios, which are not fully exclusive, the first is that their team was under a lot of pressure from management to release because it went over a year later than initially planned, so they released a half baked firmware. The second is that they are using data driven algorithms for the compensations of streaking in the sensor and simply haven't refined their models, probably both. Either way the image we get from the sensor is going through tons of processing by the processor, with enough time and data, these phenomena will be totally eliminated in upcoming updates. But for sure the correct step would be to wait before buying if it is affecting your use cases. I'm buying mostly for video, so it's not a big deal for me.
As you say, Gerald mentioned the Issue with the light. In my mind at 2022 it makes it almost obsolete....can it be fixed? And Yes, I like to see your Review of GH6. For me, Its the review I'm waiting for ;)
It does seem very odd how other reviewers, even the very good ones did not cover this in depth..... I do think it would have been better to do a review at the time and cover the good and the bad. That's what reviews are meant to be for. They will also help cement your reputation as a truly trusted channel. Love the channel by the way.
I did check with some of them actually. Some responses were like “we didn’t have enough time to test to discover it” even though it took literally 30 sec to immediately see it. Other saw it but chose not to talk about it to stay cool with the camera brand. Keep in mind many rely on the commission they get when you use their links, so it’s uncommon to find someone warn you about a camera Thank God I have a full time DP job that pays my bills so I only care about sharing the truth, not pleasing corporations or worrying about commissions
Thanks ! Great job ! what I can tell you , in my experience , BMPC 6k pro on iso 1000 when you using full battery (7,4 v and up ) you have less problem but from (7,4- 7,2v ) on iso 1000 start getting more lines .
At 6:12 you talk about the overflow of light to neighbouring pixels. But why does it only leak to neighbouring horizontal pixels and not vertical pixels.
It is related to how rolling shutters work. The sensor is read line by line and there's one set of amplifiers per pixel line and something something. Explained by an engineer friend, but he doesn't specialize in microchips so that's as far as I got.
Great job. I haven't seen this happen in any of my shots, but it is as clear as day in your video. I would love to see the next 2 videos you have planned on the GH6.
To me this looks like exetremly rare and un-realistic use-case scenario. I would not even call this "basic high dynamic range shot". As GH6 owner who never saw this streaking on any of my shots I would be more concerned if Panasonic would actually listen and fix this for all other users who do not deliberately shoot this kind of "artistic" content. Fixes do not come with on/off toggle in settings. We do not know what would be the side effects or price that we would need to pay for doing more drastical fix. I would much more have Panasonic focus on things that are benefitial for everyday user in properly exposed or real life shots. In your description I would like to see: Basic info on what lenses, focal lenghts have you used during testing. What are your settings i.e. exposure metering mode etc. If you have some real life examples of this streaking ever ruining any real-life shot please include those in the description. You could have also included waveforms so we can get the idea of how many stops you was overexposed during each setting.
@@RagingShrimp67 My understanding was that Panasonic made chaanges to minimize the banding already before or in in FW1.0 Seems that the video doesn't say wether the footage was taken before the fix or after. For sure the author of this video expected more agressive mitigation then Panasonic was willing to implement.
@@RagingShrimp67 Panasonic have confirmed the problems. I think concert shooters will be disappointed, and Pannys and M4/3 especially seem popular in that group
It seems like, that issue does have something to-do with the coatings on the OLPF of glass, which sits in front of the naked Sensor. I remember these things quite well, from my Sony A7. It's coatings caused under special circumstances light reflections interally, which could ruin some pictures.
Hey Sherif, Great video my guy. One question though because I am not very technical does the Bayer array have anything to do with this or is it just a design flaw of all CMOS sensors even if we strip away the color filter?
All I know is that it's the CMOS sensor design hat creates those horizontal streaks, bayer is in all CMOS anyway, some have a slightly different pattern than others, but don't think it affects it, CCD sensors create vertical ones BTW.
@@THEDPJOURNEY I was more wondering Bayer vs xtrans but I actually got my answer when I was recording a test shot with my xt-3 where I put a white background on my PC and shot it in a dark room and there was streaking. But I came to the conclusion that there are different types of streaking. There's the light streaking where the streak darkens the area it affects and there's the streak that lightens the area it affects and one is clearly better looking than the other. A streak that comes from a light source that lightens the surrounding could look like an anamorphic lens flare, an unwanted one of course but it is much better than a streak that darkens the area surrounding it which makes no sense from any way you look at it.
As usual, you cover issues that either other people dodge or fail to acknowledge. This was an important video for me. Even though I am happy with my Sony A7iv, I was really impressed with the features of the GH6 and thought about getting it as a second camera. But, after seeing this video, I will not even think about buying the GH6 until they fix this issue. So, I'm not sure if it's worthwhile creating more videos until this is fixed. It's like buying a car that stalls every five miles, and you have to call roadside assistance to get moving again. Thanks for your fantastic content. You really provide a great service to the filmmaking community.
Thank you so much for watching and for your support. I always hope that my videos help and educate beyond the typical hype that’s all about reading specs rather than really checking camera’s actual performance. Thanks again
I had my GH6 for a month now, NEVER had a problem with the horizontal banding, I can hardly notice that. If you are shooting towards a window, you are turning dynamic boost on anyways (actually I use it as default).
@@waynecake5867 Not having encoutered this problem does not mean it doesn't exist. Panasonic confirmed it's there and actually thanked me for pointing it out. You just didn't recreate the perfect scenario and settings that let it manifest that's all. You'll eventually find it, won't be a surprise to you when you do
so what are the ISOs I can shoot with again? Im confused, and sad. I found streaks in night shots, thought it could be from some types of lights...but then I shot daytime outdoors today, and it's all streaked. Iso 250 onwards....
I've just come across this issue in all sorts of lighting conditions, But I quickly realised, this only occurs in 100 and 120fps. I've never seen it in 60fps or lower.
I don't get why some take it as acceptable being "It happens at certain ISOs during certain lighting occasions". From what i see, BMCC 6K FF suffers the same streaking. Not sure if the newly shipped Pyxis having the same phenomenon. Hope i could see that & bmcc ff being reviewed mainly on this streaking issue as well.
Great video. Thank you. How did you make the transition at 3:55 ? Can you screenshot/share the adjustment layer settings or, if you didn't make it from scratch, share where you got it from? Very subtle and beautiful.
Great video! And just before I thought this is the one camera for me..... now it's honestly not as sure choice :/ Do you think there is any other one that can give us as quality and features in this price level now? A7IV, Pocket 6k Pro, Z-cam? Only for video... no need photography features.
Unfortunately I can’t find anything. Panasonic did create an awesome camera on paper! FULL of great features! But messed up the most important component
hello Sherif, interesting tests, while you was conducting these, did you encounter even the sensor stitching issue of the V-Raptor (producing a vertical line in the center of the frame) or did RED somehow fixed it?
I honestly didn’t notice it. I own the raptor and already had several commercial shoots with it. I’m also aware of the problem, but couldn’t replicate it
Very well done review! Thanks for the information on the GH6. Somewhat concerning for a flagship m4/3 camera. Is this a firmware/profiling issue or sensor hw issue?
this is a HW issue as mentioned across all CMOS sensors. But that can potentially be mitigated to a certain degree with FW. As of now, it's still there.
Thank You for honesty ✅ I own several Panasonic cameras with the GH5M2 being the most recent. I was hoping for a lot more from the GH6 and will wait until the GH6S or GH7 to see if these lingering problems still exist? New subscriber here 👍🏻 Cheers from Western Australia 🇦🇺
I'm on the latest firmware update on my GH6 cameras. I mainly shoot weddings and half the time the getting ready is in a dark hotel room with outdoor light coming through the windows. I absolutely hate the challenges of having to shoot different for a lot of those scenarios because the streaking comes flying in at full effect with dark rooms and the subject right up against a super bright window. Very frustrating.
Can I ask you for an opinion? to film 4k DCI do you think that the quality of the GH6 far exceeds the GH5??? Is it worth changing from the GH5 to the GH6? They tell me that the GH have noise problems in the image and autofocus...???
The full V-Log they have in the camera renders a more accurate color and highlight roll-off yes. Not sure what they mean by noise, and yes, focus is still a problem
I'd like to know more about your experience with this problem. I have certainly seen others complain of this on their Canon C300's too. Can you go into more detail? RED Helium too? Hmmm
Seems the M43 GH6 is such junk, confirmed by the streaking issue, it is not worth DP Journeys' time, hence the "THE PROBLEM with GH6 and why I didn’t review it" title.
@@peternavanac9310 As a Lumix S1H and Sony A7-IV, A7S-III and Sony FX6 owner....I can absolutely say the GH6 is not "junk" at all. Not even close. The overall image quality in most cases is literally superb.
@@clifftotten7609 That was the point of my comment. Thanks for your reply. I too find the image quality to be simply superb...with or without the "problem" found by DP Journey.
I never said it was Junk and not worth my time. I said “It’s an awesome camera” in this episode. And it didn’t make sense to review that awesomeness before I talk about that issue first. Which could be a deal breaker for some people, me being one of them.
So good to see a video from you man! It’s been a while. But it’s been a while since I’ve uploaded one too so I get it. Side note: If you ever need help testing all those cameras let me know 🤣 I can definitely make time for that 😃
That streaking looks horrible. As a previous GH5 shooter, I am glad that I went with the S5 instead. Do you plan to cover the A7IV? It looks interesting but with some flaws.
@@looklook5766 Everyday I'm blown away with the quality of image from my S5. Recently in the UK, you could get a brand new S5 + 20-60 + 50 1.8 for £1299.99. Insane! Wish it had a full size HDMI, but you can't have everything I guess :)
Glad you're back. At $2k the Blackmagic 6k (with a polarizer for this "fix") is still killing it for me. Would I like to have the FX3? Of course but that isn't in the cards....yet.
Great Review, this is the stuff we need to know! imagine having those streaks show up in a pro shoot: Not acceptable! I'll keep watching to see if the Panasonic gets this fixed...amazing camera from what I can see, but an issue like that would keep me from using it on a professional shoot.
I bought a new GH6 yesterday on the proviso from the store that I could return it if I came across the streaking issue. The cam is loaded with firmware 2.2. I recreated the streak in about 20 seconds. Shooting a light source with a dark background it appeared immediately. I do a lot of event filming so lots of light in dark rooms so there's not a chance I could rely on this camera with client work. Maybe that's why it was so cheap too? I got the cam, the 12-35 f2.8, a spare battery and a 128gb CF express card for £1700. Kinda thought that price was too good to be true. This fault is unfortunately pretty bad rendering this camera poor and useless for client work. Pretty gutted about it. Loved the GH5 so was hoping for this to be another solid workhorse.
@@THEDPJOURNEY I did. It was because of your film I was cautious and got the store to guarantee I could bring it back if I found the issue. I had seen lots of people on the forums saying their's were fine and the firmware had eliminated it so wondered if it could be down to the individual camera but having seen it for myself I think the sensor is compromised and those people that haven't experienced it have just been lucky. It's there and it's pretty bad - completely unusable for my client work. I can't see how firmware can solve it. It looks like a hardware issue to me. My advise to anyone wanting to use this cam for professional work would be to avoid it big time unfortunately.
Technically it is fixable, but this sensor seems to have it at a very high level that it becomes hard to eliminate completely. Or maybe it’ll just take so much resources for them to fix which is not worth it.. who knows… shame since the camera packs so much awesomeness. Like buying a Ferrari with a faulty engine
@@THEDPJOURNEY Absolutely! The specs for anamorphic and raw are amazing and the amount of codec options. It's why I took the gamble even knowing the issue, hoping the firmware had limited the effect but 2.2 is still no better really which is concerning. I would have thought this would be a priority. I took it back today and exchanged it for S5IIX when it comes out. A whole new mount eco system to adjust too but that camera also looks seriously impressive!
Check all indoor scenes in all Hollywood films. The list is endless. That’s not the point after all. If you find yourself in this situation with this camera. Then you won’t be happy with the result.
I don’t really understand what you are trying to say here. You’ve reviewed a lot of cameras and they nearly all have them apart from the $30,000 red camera. We’re talking about a very different price point camera here and there are obvious jobs for this camera. Your light streaks will appear if you use no lighting at all in my opinion so I would never shoot the way you’ve shown in this example. The comment about your clients will complain about your shots will not be because of the camera it will be because you didn’t use professional equipment such as lighting. I don’t think this is a very good review and telling people not to buy this camera based on the light streaks.
You can work as cinematographer also with a 2.000$ camera...and if you work as cinematographer, you play a lot with contrasty scenes. You can't deliver material with this big issues to your clients (creative agencies, final deliverables, etc...) At the launch of the gh6, youtube was full of videos with the problem of the light streakes...if you didn't see them, it doesn't mean that other people will not see the problem.
First: I compared it to the GH5 as well which is cheaper and performed better. I just tossed In the RED literally because Panasonic told me all cameras express this streak, even RED. Because they know I own it. Second: no idea how will I shoot with no lighting?! Unless you mean not directed into the sensor? In that case when everything is very midtown with very diffused light, then probably you won’t notice the streak. But do you wanna be limited to that? Cameras are here to give you the freedom of shooting whatever you want, not to restrict your creativity. Third: can you please define professional equipment? That’s so irrelevant man. A light source whether it’s the sun or artificial light, they all fall under “light source” the sensor doesn’t differentiate. It’s just a silicone layer that’s sensitive to photons Lastly: I never said “telling people not to buy the camera” I said “I will not buy it” you do whatever you like. If you like it, then buy it. I’m not here to tell you what to do, I’m only reporting what I saw and telling you that even Panasonic admit it has light streak… even when using “professional light”
@@THEDPJOURNEY I really appreciate all of your videos and especially this one, even though it’s not awesome for me as a GH6 owner. If anything it may put pressure on Panasonic to fix it. Thank you so much for this.
UPDATE: I hate to say it, but Firmware 2.0 still expresses the same streaking problem. Let's wait for the next one
:( :(:(:(:(:(:(:(:(:(:(:(:(
I noticed this last night while recording externally on the S1
I'm wondering if this is something that firmware could even address. It seems like it might be more of a mechanical issue with the sensor.
Damn I was hoping the firmware 2.0 would fix this. I just noticed this issue in some of my film tests I did yesterday. Updated the firmware just after. Was really hoping it would be fixed!
I had this in my cart and was just about to buy. This video saved me the hassle.

I haven't noticed the light streaking issue in real world use on my GH6. So far, I'm very satisfied with the camera.
Sounds good. Just know that maybe one day you will notice it and it’s be impossible to fix. That’s all I’m saying
@@THEDPJOURNEY if its not noticed yet, why would be in the future? sound like you just want the camera to be faulty.
resell it as bad camera !! go for RED camera !! way better !!
Panasonic confirmed this issue exists in all their cameras, no exception. Not seeing it only means he didn’t use it in the optimal scenario that shows it. Best of luck
GH6 Owner here: great video, I like how you showcased the problem and explained why it happens, plus showing it on other brands and models, personally I haven't seen that issue in my footage, and I've shot in high DR situations, I was aware of this "issue" before buying my camera but upon getting it and using it In several occasions, I don't feel like it is a big deal to be honest, a lot of cameras with a CMOS sensor have this, it is more pronounce on some but it isn't something that huge IMO, again I can't speak for everyone but as far as my GH6 and my footage, I've haven't experienced it, this might show up in extreme situations, but it hasn't for me. (not defending the camera or anything, it's just my honest opinion)
Yup. Totally agreed. I already made sure it’s very clear that in those specific situations with high contrast such as window setup. Which to me is very limiting to my creative process. I can’t tell my clients:”oh sorry we can’t shoot facing the window because the camera can’t handle it”
Again, the GH5 works great. So why are they going backwards now
@@THEDPJOURNEY totally understand, I’ll make some more testings on my own to check if depending on the lens, the streaks are more pronounce or something
@@AndyLSB let me save you time, it's not the lens, that's the first test I did to rule out optical refractions. That's why i said "not suing anamorphic or any lens filters"
Again, Panasonic DID acknowledge the problem, they even thanked me for pointing it out. So the problem is there whether you found it or not. You just didn't shoot in the perfect setup that highlights it.
Try shooting a candle or a single light source in a dark room in V-Log at ISO 2000
@@THEDPJOURNEY oh ok awesome, I’ll try that tonight then, I’ll let you know my results.
Maybe iso 4000 will show more
Absolutely facinating. I knew about this problem when I was ar NAB. I took my GH6 out to the Vegas strip for 3 nights shooting everything at 2000 ISO VLog. I shot a couple hundred clips all exposed hard to the right but keeping higlights just a hair under cliping. After pixel peeping those couple hundred clips, I found only one single clip that streaked. It was the white Mirage building in the night sky. Even stranger....of the 10 similar shots framed in a similar manner, 9 of them did not streak. It was only one exact angle and exact exposure that triggered it. All the other Vegas strip street shots were prefectly fine. It's strange how random it is for me. Everything I shot was with in-camera noise reduction pulled back to "0"
As i demonstrated, it all depends on the camera settings and the situation you are shooting in. Keep in mind the more lights you have the more streaks will overlap each other and you might end up having a fully lifted image rather than one light streak because it’s just one light source. In other words, if you just put a vertical light tube along the side of your full image, you will not see the streak simply because the streak is literally covering the full image. Hope that makes sense
@@THEDPJOURNEY I shot about 10 files on the street with the White Mirage building in front of the night sky. It’s weird…one specific angle caused perfect streaking. The next file was just me on the same shot, just 20 feel moved over. That same building, same exposure and same night sky had zero artifacts. Moving down the street several more times and that streaking was still gone. I was expecting to see the exact same problem on each shot because each one was only “slightly” different from each other. But no…only one had the problem. And that one that had it?…had it strongly. It’s so arbitrary. I was expecting to see it in many many shots but no,…it’s like rolling a dice. It just happens out of the blue as a matter of chance? Please keep talking about this. I will do further testing myself on this. Spectacular video that you made on this.
@@clifftotten7609 rolling a dice is a perfect analogy, would you roll the dice when it comes to client work?
Try this... go in a dark room, and light a couple candles, set it to V-Log ISO 2000 and see what happens
@@THEDPJOURNEY Agreed....yes this is something that concerns me. I'm taking my GH6 to Yellowstone National park in 2 weeks. I'll be shooting 90% daylight shots in VLog on Eagles, Coyotes and lots of bears. Some evening shots on the Hayden valley wolves. I'm certain this kind of outdoor shooting wont show any problems...but Im curious to see. This is 100% personal work. Please keep invistigating this issue. You are on to a super interesting subject with this!
@@THEDPJOURNEY So you are acknowledging you have to use certain settings and push the camera in a certain way to get it to streak?
Thanks so much for bringing this up! I immediately tested my Canon R5 C after watching this, and indeed found that it has the same problem. I brought the camera to a Canon service centre nearby and the technician found that their sample unit also behave the same. She said she would report this issue to Canon HQ, but in the meantime there's nothing she can do to help.
I really do hope Canon can somehow mitigate this issue because the R5 C really is not cheap.
Really happy you mentioned that! cuz I've ben hearing about it nut didnt get the chance to test it yet! I was in fact planning to buy it as well, but it seems I might just hold back then
they fixed the problem with software on canon r5 having the same problem. There is also a video on the subject. ua-cam.com/video/dfenxw0OKbc/v-deo.html
After working with this camera for a few weeks, I found a fatal flaw with the footage higher than 60fps. There's a red line though EVERY SINGLE shot. ...and Panasonic won't refund me. They want 2-8 weeks to "fix" it.
Oh damn. I assume that’s only in your camera.haven’t seen that so far in the one I have
Thank you! I’m still reviewing all camera options. I canceled my GH6 order & now I’m back to contemplating which system to spend my $3k on.
just came from your video to check this out! ...what the F man...I was kinda gaining some big respect for this camera despite KNOWING about the AF issues. I recommended this camera to my friend and he almost got it. opted for a blackmagic pocket 4k instead. he'll upgrade to 6k at some point
@@cyborgchimpy this guy is on something. It's not a real issue. Just someone who hates that m43 exists.
The issue is not caused the way you have explained it. So let me provide a better one - since I do design cameras. Each sensor has a "optically black" area either on left or both sides of the active picture, shielded from capturing light. As all the pixels of one line are converted simultaneously, next the average of those shielded pixels is subtracted from the active area data. This is called Black Level Correction (BLC) - restoring the black to a digital zero, on each line of the picture individually. The problem occurs when the shielded pixels are locally affected - either by overflowing charge into them from a highlight area, or if a light reflected on specific angle gets under the shield and onto those pixels. Both of this are specific to the design and build of the particular sensor itself. So this then results in artefacts that look like bands, but really its just a grouped FPN issue, as every line may have a different imprecision in black-level correction. PS: I do not know what the DRBOOST is about on technical level.. hate the marketing words without deep explanation. So no idea how that comes into the picture.
Thank you so much for the explanation, it did help me better understand what’s going on under the hood. Of course with that knowledge I would be careful sharing it with other filmmakers, since we are not on that technical level as yours. I was of course just trying to over simplify things, knowing that this will not accurately explain the problem. But as you know it’s just to give an idea rather than go into the science of it. Thanks again for watching and thanks for the clear explanation
Woah,....I'm a bit obsessed with this issue. I just took out my Sony FX6 and shot some SLog-3 and I got a very similar blooming/streaking using an iPad in a dark room. I have the FX6 set with noise reduction set to "low" and it has the SAME GH6 horizontal banding lines. It's VERY interesting. Not only is the FX6 showing grey banding but the noise itself "runs" and dances sideways with the bands. I swear that I have never noticed this before but not that I'm hunting for it, it's showing up. It's kinda crazy. Can any other FX6 owners test this with a "square" light source like an iPad?
*Edit - Yup on my second test, I can absolutely confirm the Sony FX6 is doing this too. It seems to be a certain "ratio" between the light vs. shadow. There seems to be a bell-curve "problem" peak point. When closing and opening the aperture, as the blooming increases, the banding will get stronger. It "peaks" at a certain bight to dark ratio and then "fades" as the light gets more intense. Moving the aperture back again will bring the banding back until it peaks and then recedes again. When it peaks, it's pretty strong. Absolutely fascinating...wow. The Sony FX6 has this too!
Oh wow!
I’m honestly considering adding this kind of test to all my future camera reviews!!
You should make an episode about that man
You should make a video if this is really happening. I cannot reproduce with the sony fx6.
@@burritobrosvideos8060 - I didnt use an actual iPad. I used a Tripplteck tablet that has 1000 nitts. I placed it in a dark room with full brightness. I had a large black plastic sheet behind it. I shot in SLog-3 and ramped up the gain step by step. I noticed the artifact peaks at a certain white/black "ratio". It's not there in lower ISO's then appears, then fades away as you go up. There seems to be a certain peak bell curve or "sweet spot" that it lives in. If you are below it or above it, it's only minor. When you hit the gain, it appears. It's odd and fascinating.

Blackmagic Cinema Camera 6k FF has entered the chat…
Whoa, that's nuts! I just watched a video of someone comparing the Komodo to the R5c and R5, he's switching to the R5c, and he did a dynamic range comparison between the two. The Canons both had this issue fairly badly and the Komodo didn't seem to have it. I was quite thrilled but I will be testing my Komodo to see if I can spot it. I'm hoping not, but I will be comparing to my S1H.

Hey thanks for this. I am sure it drove down the price of the gh6, which I picked up for 1500 dollars new a few months ago. The 5.7k pro res hq images are terrific. I updated the firmware to 2.1 and have really tried to create your scenarios for streaking. I thought I saw one sort of streak and moved the camera about three inches to the right and it was gone. Then I changed the iso and it was gone. I have shot maybe...200 hours on the gh6...in every lighting condition I can conjure up and--no streaking. I bought the camera thinking this might be a workaround, but now realize it is a non issue, at least for me, and the best friend to those of us who seek maximum image quality at the lowest price possible. I really like the images it produces and look forward to picking it up and shooting every day. I am a former journalist who does not like bs or corporate pitch people, so...my views. I really like your videos. Keep up the good work.
Good to have you back!!!
Yeah been a while. Always tricky to balance my full time DP life with UA-cam. Thanks again for watching
0:19 Been waiting for a full breakdown of this. I found this in two different copies of the GH6 that I bought. I reached out to mft facebook groups and even the Lumix UA-cam channel and all I got were crickets. They still haven't addressed it. That and a couple other let downs with the GH6 led me to finally switch out. Currently happy with my Sony full-frame setup. Much more expensive but it's definitely worth not dealing with the shortcomings of Panasonic. Thank you for this breakdown!
I heard about your shortcomings.
Sony A7IV? A7SIII?
@@Alexrocks1253 fx3 and A7iv
Another GH6 owner here that has never experienced this. I just went back and looked through a bunch of my footage as well, and couldn't find any examples. Very interesting though, I'll certainly be more aware of this in the future.
Sucks that a lot of people will swear of the GH6 forever now because of this video, when probably 99% of them would never experience this, because it is an absolutely amazing camera, and I wouldn't trade it for anything (well, not literally, but anything comparable) .
I guess you're lucky none of the scenes you shot expressed that streaking, I assume they're all morning outdoor shots or just high key shots with no lights shining directly into the sensor. But that does not mean it's not there, it's jut you didn't shoot in the settings and that induce it the most. Panasonic did replicate it in all their cameras and they're confirming it's there, no denial there. So your camera has it and one day you'll be able to see it when shooting in similar kind of high DR scene like the one i featured here
@@THEDPJOURNEY So it's like herpes...
@@THEDPJOURNEY I only shoot in extremely high contrast situations. Bars, nightlife, etc. I can't find any examples of this popping up in my photos. Over 20,000 photos over the last couple months, with about 15,000 of those happening in various high contrast situations. Can't find even one example after scrolling through for the last half hour.
@@THEDPJOURNEY So I was finally able to replicate this today. I did find it to be very lens dependent though. Using a vintage OM lens on a speed booster it was almost impossible to get it - DR boost had to be on, and exposure set for the light outside the window, while the inside was quite dark. The native MFT lenses I tried were the most apparent (25 f1.7, and a 12-50mm f3.5) while the two lenses on the metabones were much more difficult to produce it, but also varied a bit (1980's OM 24 f2.8, and a Tokina 20-35 f2.8). I almost always use the metabones adapted glass, so I'm guessing this is why it's taken so long to see this. Also, I don't know that I'd ever shot inside while exposing for what's out the window - and this time was just testing out lens.
Thanks for letting us know this issue. Never realized that cameras could be affected by this issue.
Hard to believe, thanks for watching
Need a sequel on this since it appears to be the same issue present in the new Blackmagic cinema camera 6k FF. Is that maybe the reason you won't review that unit?
I’ll be checking it out soon
@@THEDPJOURNEYcan confirm. It’s way more pronounced on the blackmagic Cinema Camera 6k FF.
From my experience it streaks in well lit conditions too( if you’d like I provide some sample footage via email).
I’ve had the camera replaced twice and been in contact with blackmagic who provided the same response as Panasonic. Blackmagic told me shooting events is improper use case because it’s a cinema camera so I should be controlling my point of highlight like any cinema camera in a studio set….
Most BS response I’ve ever had with a camera company.
For a few seconds I thought those light streaks were image burn-in on my computer screen...I scared myself for no reason.
hahaha... it's the camera
So great to see you upload!
Yeah it’s been a while… should post more frequently now, wish me luck
Thanks for the video. Also I enjoyed watching your editing technique-!!
Thanks for watching 😊
Thanks for the detailed heads-up on the light streaks. Really looking forward to the continued review of the camera!
More to come!
I've been shooting with mine for over a week now in all sorts of scenarios and never once had this issue. Shooting in 5.7K 24p/60p & C4K 120p 420 10bit internal VLog. I've filmed with bright windows as the only light source in a completely unlit room, exteriors, interiors, etc and never noticed this issue. I wonder if it was a limited run of early cameras or a bad batch of sensors?
EDIT** I've also been shooting in ISO 400 (Native) or with DRB at ISO 2000 (Native when using VLOG)
You’re lucky then. The issue is there, a Panasonic did recreate the issue in their labs and that was the reason why you heard influencers like Gerald Undone say they got the camera late. Simply because they were working on a fix.
Try to recreate the setup I had and let me know what you get
Mine does it. I just bought mine two weeks ago.
@@northislandnow8858 They all have that problem, Panasonic confirmed it 5 months ago. You're not alone
Your footage does have the problem.
@@burritobrosvideos8060 You're right, I was able to get it to show by setting it up looking out a bright window and then adjusting exposure until interior was completely dark. Not really a real world scenario haha. In real world use, it's never been an issue. Either buy and enjoy, or worry for nothing and miss out.
Great to have you back, Sherif. Such a shame about these streaks. I'm so in tune with my GH5 and GH5S that a GH6 would have been a logical progression for my aging cams at least from a workflow and ergonomics perspective. I'm amazed the GH5 is still ticking after all we've been through together. Where would you go next if my GH5 bites the dust?
I would wait for the S1H MKII
@@THEDPJOURNEY Can you explain the rational of S1H MkII over GH6?
This is completely fixable in firmware and clearly the camera is either overcompensating or undercompensating. It is a very bad move to release it in that state, but I am sure it will be fixed in few weeks at most.
@@RagingShrimp67 It's hard to believe that this won't be fixed..
Since you are so in tune, why not the underestimated GH5 Mark II… Even if you were to go with the GH6, or any other camera, your workflow would be affected. The GH5II, does have a newer processor (which means firmware updatable), and IQ is shaper, as well as better in lower light. Plus the AF is better too, usable, similar to the S5, but with a smaller sensor it probably is even more effective. Most importantly, the GH5II is cost effective, and you would not need to change much if anything at all related to your process…
…
@@RagingShrimp67 I'm hoenstly not very optimistic about being so sure they'll fix it. They literally acknowledged the problem when I first reported it Mid January, and it's been 4 months now and they didnt fix it. Not just that, when they launched the camera, they told me they're ok with the problem as is now. So they might not even be trying to fix it. I hope this episode would add some pressure. it's for our benefit after all what I'm doing here.
Well thanks a lot for the heads-up! I always value your comments and trust your evaluation explicitly👍
So nice of you
Using an iPad with a bright white .jpg in a dark room...I was able to force this blooming/streaking artifact....but only partially. Now that I have being testing this and delibretly trying to "force" this blooming, I have noticed that I can only get this problem on shots that were unusable to begin with. I could not get the artifact to to appear on well exposed shots. I could not get the artifact to ruin "good" shots. I could only get the blooming/streaking problem to appear in shots that were already really bad to begin with and were already unusable. Does that make sense?
Absolutely, thing is, “cinematic” filmmaking is all about shooting into the light, which is my fav type of look. With that said, most if not all my shots will be destroyed. I didn’t really spend much time trying to force it, it was pretty easy to come by honestly. Not sure why it was very hard for you to recreate it.
In the end, if you feel you’re comfortable with that, then it’s all good.
Just keep in mind that there’s always a chance for it to ruin your shot. So be careful
@@THEDPJOURNEY - Agreed. Yes,...this is concerning to me and something that I take seriously. Although, my GH6 is intended for Alaska and Montana hiking. I have a large library of grizzly bears and wolves that I created with my GH5. I dont see this ever being a problem in daylight shooting of wildlife. But yes...this blooming/banding issue still wiil certainly still be in the back of my mind. Keep up the excellent work that you do. Im a big fan of your channel!
I've noticed that I can see the streak when looking at the screen, but the moment I hit record the streaking completely disappeared
The video feed on the monitor and the recorded video are on different circuits. The streak will not look as bad in the footage as it is on the the screen, but it’ll still be there
Wow, man! Thanks for the video! That’s a huge issue, wth, why nobody truly talked about this? It’s a dealbreaker for sure, it’s basically unusable.
I would never buy Panasonic anyway because of their braindead position on autofocus, but this just confirmed it for certain: from the leader of the industry in the video mirrorless world they’ve turned into a company that produces subpar products with major flaws. Screw this. It was the reason for me to switch from Canon a long time ago, and now Panasonic is going the same route. Pathetic.
But once again, big thanks for this extremely important video!
Thanks for watching! They do have really great cameras, I used them in so many commercial work. The quality is usually awesome. But the AF is of course a major flaw compared to others these days. But I know they're working on it.
But this streaking issue, was pretty unexpected. I'm now doubting their QC
The S1 has internal 6k, full frame, 4k 60 fps with a crop, no QC issues, etc. I dont know how you could judge all of Panasonic based on their attempt to push M43 beyond anyone else. The S5 and S1 are incredible quality, and have been supported so well through firmware. What's clear is that a larger sensor simply is king.
@@CanditoTrainingHQ spot on. The S5 is just insane value for money. Saw it was on sale for under $1500USD a week or two ago. 80% of my Sony a7S III capability (and exceeds in some cases) for ⅓ of the price. Agree the S1 is WAY in the shadows of the S1H. You can picked them up used for less than a GH6.
Meanwhile I'll continue to deal with my Sony's star eater issue....not like they have had long to fix that...oh wait...only since the gen 1 a7 series. Don't get me started on the Canon Cripple Cam marketing, the R5C is an amazing camera, but let's not pretend like Canon don't speed limit video on their hybrids to protect their cine line. Yes this streaking is an issue, and yes Panasonic's response is disappointing. It makes the GH6 a no go for anyone concerned about IQ, which would be one of the main drivers to upgrade from the GH5x line. One bad issue present in a particular scenario does not mean Panasonic have lost their relevance.
@@CanditoTrainingHQ They are decent cameras, sure, but with garbage AF. And unfortunately Panasonic is doing a “Canon” on us all by refusing to put a decent phase-detect AF there. I don’t like Cripple Hammers, I’ve been using Panasonic camera with shitty unreliable AF for long enough already, I don’t want that anymore in my life.
Thanks for this much needed video review. Was eagerly waiting to hear your opinion on gh6.
Glad it was helpful!
So great to have you back, Sherif.
Great to be back
I have used my GH6 for a month and I can hardly notice this issue. I am feeling that some people are over exaggerating the problem.
Panasonic HQ in Japan replicated the problem and as mentioned they do acknowledge its presence in all their cameras, so the problem is there no doubt about it. You were just lucky that you didn't shoot using the settings or scenes that makes it prominent.
@@THEDPJOURNEY I know, this issue is even described in the quick guide out of the box! They say it's a character of the sensor. If you are going to shoot towards a window, you turn on dynamic range boost anyways. Besides, I am a cave photographer and filmmaker. When a headlight shines towards you in the cave, the scene contrast is going to blow any camera off and show any in-perfection in the lens. However, I didn't found the banding an issue. The issue I found (the real issue that nobody talked) is that the GH6 drives focus motor more forcefully than the GH5, thus creating lots of noises that make the in-camera mic unusable.
This problem is pronounced in several camera's...but the Panasonic M43 GH6 is so bad the video is labeled "THE PROBLEM with GH6 and why I didn’t review it" regardless of the stunning video quality and feature set. A little FF bias from DP Journey?
@@peternavanac9310 No, in practice, this is not an issue.
Thanks for the info, very in-depth. I am assuming you tried this in version 1.2 of the camera's firmware before posting all of this? I have never come across that issue but am interested to try and recreate it.
Yes I did, it's the same, Just posted the results in the community tab
@@THEDPJOURNEY Thanks, appreciate the update.
@@stevelitton my pleasure
We've been shooting a lot of outdoors with GH6's since it came out, and are very pleased with it... Never noticed this issue, I guess in real world this is a very rare situation, and Panasonic decided to release the gh6 with this issue hoping it won't get noticed by many...
The issue won’t be clear in high key shots, only when you have a dark setup with a strong light source shining against that dark, like almost all indoor room with a window shot, a concert, etc…
Love your reviews! Well done!
Glad you like them! Thanks for watching
Well done. I say wait and see if Panasonic fixes the issue then do a full review. Your reviews are always the best.
Fingers crossed!
At this point in time I somehow get the impression this issue is not a deal breaker for most (97.5%?) owners. But I do get the concern considering the GH6's cost. I am good with it but I am not a professional submitting an entry for an academy award.
Yeah, problem is, being a full time DP, 99% of my shoots are commercial work for clients that will not hire me again if they see such issues with the sensor.I can’t risk putting them or myself in such situation
@@THEDPJOURNEY Understood. As a professional using your gear to put food on the table, I see where this issue is quite pertinent.
1 year later, I still love my GH6 and that streaking has happened only in very specific extreme situations when anyways the image would have been crap. So no big issue as this video attempts to make it. This camera is awesome and I still love to use it everyday.
Really happy the streaking is not causing you any issues. It’s a great camera after all, no doubt about it, but me personally, I’d never use it on a commercial set, can’t risk that streaking ruining the client’s shots
@@THEDPJOURNEY It wouldn't because there is probably zero chance you experience it. I think the best situation to test the issue was the total eclipse we had last week. Zero problem. Not seen one sign of it. That's because anyone who can expose well a shot should never run into this very niche issue.
I find it a little over the top to talk about "the streaking issue". I've tested mine extensively ever since I've had the camera, in october 2022 and managed to see it once when I was at 25 600 ISO and pushed the exposure to its maximum capacity filming a full moon. Not exactly something I would do if I was filming for a client!
I mean, Panasonic themselves acknowledged this was a problem, and they tried to fix it in many firmware updates till they told me it will never be fully fixed. Calling it an “issue” or a “problem” is quoting the makers of the camera itself, not just my assessment. So again, I’m glad this issue is not affecting your workflow, for me, I’m just waiting for the GH7
All the best
Your videos are incredible! So well put together
Thank you for the kind words and thanks for watching
Thanks for the excellent demonstration. I’ve shot a fair bit with the GH6 and not had streaking issues. I will do some tests and share my findings.
Same here… I shot many other test shots and didn’t feel it when the footage is mainly broght. Only in low key shots where you have sharp contrast like the example demonstrated in the episode.
Awesome, man! I've been waiting for one of your videos! I hope you can release new videos more often, cheers! )) 👌
Thanks for the support. Yeah illl do my best. Juggling DP work and UA-cam is not easy apparently
Conclusion: This is not a problem if you use normal color shots. Gh6 problem is a little disappointing but it's Only visible when you have very bright next to very dark high contrast: (i.e. black and white is the worst example of this),
and it is worse if you boost contrast and luts. (all Cmos cameras have a little of this).
None of the GH6 images I've seen with normal chroma range shows this problem.
In this regard the Gh5. Gh5s and Gh5/2 and Pana's Full frames are still highly usable.
And so is the GH6 if you don't use luts and high contrast with as shown here.
I suggest another test with full color, (with and without luts) will demonstrate a good outcome
The three gentlemen referred to in this clip are all very good in this game , including Gerald ; -)
If you don’t have a high contrast shot with mid to dark areas next to it, or super soft overcast look… then you should be relatively ok.
But you never know what situation you’d be in on set…mixed with your camera settings.
That’s what scares me, the creative restriction
@@THEDPJOURNEY You cant win that kind of talk with a gh6 fanboy ^^ I see so much comments and hypes about the gh6, but in my world its not a very good cam for cinematography. There are better cams i would buy. I have the S1H and love the cam very much. Thats an amazing image. The only thing i hate with the S1H is that i cant change the shutter speed and the exposure together.. ANd the rolling shutter. But the image quality is absolutely amazing like your fx3 and bmpc
Lmao. Why would I pay over two grand for a camera and have to not use luts are you out of your mind or just some clueless troll?
Very well done review. Crazy this is the first I’m hearing about the streak issues. Love my S1H BTW!
Thanks! 👍 S1H is great
Thanks for pointing this out. But I bet in 99% of uses, it wont be a problem.
My Problem is I think Dynamic Range Boost feature is gimmicky for what its worth. I wish it was Dual ISO instead.
Yeah I’m here to point it out and tell you how this will affect my decision in using the camera. I’m not telling people what to do. And yeah, I wish the DRB could go lower than ISO 2000 like dual native iso
@@THEDPJOURNEY This time I used the cmos from non-sony, and used the cmos of sony. This is the reason why Panasonic users thought that the image quality of Panasonic was good. The s1h Mii S5mII is likely to use the cmos of Sony, the noise level and image quality. If so, I will I believe that many users who like clean and pure pictures will be lost.
Well it does function as a dual native iso....the iso performance in low light clearly gains the same advantages seen with a dual iso sensor, and the entire technology that the dynamic range boost is based off of is the presence of 2 separate sets of iso circuitry. It IS a dual native iso sensor, they simply implemented it in a way they felt was more useful. This way you can get both the dynamic range improvement above iso 2000, and the iso improvement. I don't see your problem with it.
I can compare it directly to a gh5 a g9, and a bmpcc4k. It trashes them all in high iso tests. Only the gh5s and bmpcc4k are close in performance, but my new gh6 instantly convinced me to sell the bmpcc4k. It's simply unnecessary if you have a gh6.
I've never seen the light streaking issue. It's obviously not a problem even in high iso shooting unless you are pushing the image trying to recreate it.
@@Whatsup_Abroad You are right. I did not hear about the Dual ISO at the launch so figured for some reason it did not have it. So that's good!
But now the question. GH6 vs S5?
@@chrisklugh If you show up as a videographer to a professional set with an s5, and another guy brought a gh6 and they hired based on cameras every cinematographer I've ever met would choose the guy with the gh6. It's feature set is far beyond the s5. More, higher framerates, better codecs, better video quality, better stills quality for certain types of shots (100mpx high rez handheld is fucking amazing, I got some bananas shots out at a zoo recently even without a zoom on me), faster drive speeds, better af in 60p, timecode, real vlog included in the camera, etc etc etc.
The s5 is a low-end enthusiast ff stills camera that serves as a decent video camera. The gh6 is a full on cinema camera with every industry leading feature on the market that also takes ridiculous still life and landscape and posed portraits at 100mpx brought down to a reasonable price by using a smaller sensor. It is FAR superior as a creative tool. The s5 only really makes sense to me if you are using it as a cheap entry to the panasonic ff system and are planning to upgrade soon to something like the s1h and use the s5 as a backup. If you are actually looking for a go anywhere do literally anything camera the gh6 is even a better choice than the s1h.
Features Trump the tiny image quality gain you get from full frame IMHO.
I bought this camera 15 days ago, and I'm very happy with it, and I did the tests and it doesn't have these stripes even with DR On and DR Off. ❤
Glad to hear you’re happy with the camera, it’s pretty awesome and full of great features. Panasonic did confirm to me directly that this issue exists in all their cameras, not seeing it does not mean that it doesn’t exist in your unit. You’ll eventually see it sometime when all conditions are right to induce it, hope it won’t be on a shoot for a client
@@THEDPJOURNEY thanks for the information, I really did the test and not seeing the problem I thought my unit would not have the problem, I hope they release an update soon to solve this problem. thank you friend!
@@THEDPJOURNEY Did they say anything about a possible fix in the future or it's going to stay like this?
Wow, so much work went into this video! Thanks, can’t wait to see the next follow ups 👍.
Glad you enjoyed it!
There was an update on July 11th of 2023. Did this fix the streaking issue? Glenn Fricker from SpectreSoundStudios found what he calls the "Red line of death" in slow motion. Did you also experience the "Red line of death"?
I didn’t test the latest update actually. Since I’m not suing this camera at all because of the streaking, I didn’t see the red line of death LOL
But I did hear about it.
Panasonic dropped the ball this time on that sensor unfortunately
Really well done, as usual. Very enlightening.
Thank you
Thanks so much for making this video. I hope it helps to light a fire under Panasonic's rear end and get them to address the issue. However since they have known about it for over 2 firmwares now, I wonder if this is an unfixable hardware issue with the sensor.
I was wondering the same thing as well, I hope a miracle will happen. The feature set of the camera are so good that it would be a great waste
100% fixable.
@@THEDPJOURNEY They have an extremely good history of supporting and releasing firmwares for years after release, I am not worried about it.
@@RagingShrimp67 Yes, we all remember the countless firmware updates that fixed the AFC and made it as good as Sony......oh, wait...
AFAIK the issue is already fixed.
Either way we'll wait and see, no one is forcing to buy the camera if it's not good enough for their use case.
Also comparing AF to streaking shows very poor technical understanding of the topic.
I had no idea BMPCC6K Pro has such problem! Thank you so much for such review! I wonder if Panasonic S5 has the same problem
Yeah it was a surprise for me too. Haven’t tested the s5 yet
@@THEDPJOURNEY i own both of the cameras, S5 i’ve bought thanks to your videos and now i can’t decide which is better for me)) I love 6K Pro, but lack of stabilisation is killing me…
Mate I noticed it also while the dude from CIneD was reviewuing it. Everybody does not payes attention to it, they just mention it and goes next, cause it was beta and they never touch that camera again. When I noticed it, I was like wtf? seriously?

@@egran2150 Great artist do not wait for the perfect tool or instrument, they are that tool or instrument, and will make art with whatever is in reach…
There is enough footage in the wild with the GH6 or any of the other cameras with similar sensor types, that show it’s not a hindrance.

Awesome and very informative videos as always, Sherif bek!
Glad you liked it! Ahmed Basha
Hey I know this was a controversial video(in so much that it highlighted an issue that upset people) and the drama around the GH6 was massive at the time, could you clarify something you said in this video, you mention that the low iso circuit expressed bad enough streaking you would avoid shooting in these iso's all together. Do you mean in genreal or in these lighting conditions?
I meant mostly in these high contrast conditions, but even in low contrast it’d still express that streaking
Thanks for this. I was probably a couple months from buying one. Looks like I’ll wait for an S version that’ll likely have more precise sensitivity.
Glad this video was useful. Thanks for watching
OMG! I received my GH6 last week and have not had time to use it, so I was really disturbed by your findings! I decided to set up a series of tests but It failed miserably on the first one so it is going back tomorrow! For anyone wanting a quick test just put an iPad a meter or two away on a table in a slightly dimmed room and the ugliness is there to see as clear as day. There is no denying it! I replaced the GH6 in the test with my GH5 and it was a night and day difference with the GH5 showing slight blooming but minimal smearing. Yes the GH6 had the superior quality of image but it was totally ruined by the smearing so it would be just as unusable in the same circumstances! Truly disappointing! Thank you so much for telling the real truth about that sensor problem. I very much doubt this can be fully fixed with firmware! 😔🙏🏾
What do you call fully fixed? It can definitely reduced below visible and noticeable levels in firmware.
@@RagingShrimp67 If you saw what I saw in my test or do your own I think you might change your mind! Fully fixed would be to the same level of what the GH5 copes with in the same tests! ,In my own test they were worlds apart! I hope you are correct because otherwise the camera is awesome, it is so good that I bought all the Olympus 1.2 primes last week to go with it!
@@EugeneMaynard There are 2 scenarios, which are not fully exclusive, the first is that their team was under a lot of pressure from management to release because it went over a year later than initially planned, so they released a half baked firmware. The second is that they are using data driven algorithms for the compensations of streaking in the sensor and simply haven't refined their models, probably both.
Either way the image we get from the sensor is going through tons of processing by the processor, with enough time and data, these phenomena will be totally eliminated in upcoming updates. But for sure the correct step would be to wait before buying if it is affecting your use cases. I'm buying mostly for video, so it's not a big deal for me.
@@RagingShrimp67 Panasonic Japan was aware of the problem as early as a month ago, with volume responses and returns from Chinese users.
@@jhu7639 a month is not enough time to fix this kind of issues, I expect 3-4 months.
As you say, Gerald mentioned the Issue with the light.
In my mind at 2022 it makes it almost obsolete....can it be fixed? And Yes, I like to see your Review of GH6. For me, Its the review I'm waiting for ;)
Doesn't the Raptor have it's own stitched sensor artifact issue?
They fixed it apparently
It does seem very odd how other reviewers, even the very good ones did not cover this in depth.....
I do think it would have been better to do a review at the time and cover the good and the bad. That's what reviews are meant to be for. They will also help cement your reputation as a truly trusted channel.
Love the channel by the way.
I did check with some of them actually. Some responses were like “we didn’t have enough time to test to discover it” even though it took literally 30 sec to immediately see it. Other saw it but chose not to talk about it to stay cool with the camera brand.
Keep in mind many rely on the commission they get when you use their links, so it’s uncommon to find someone warn you about a camera
Thank God I have a full time DP job that pays my bills so I only care about sharing the truth, not pleasing corporations or worrying about commissions
So Glad I got the FX3.. It's my workhorse, and I won't be switching for many years to come.
Thanks ! Great job ! what I can tell you , in my experience , BMPC 6k pro on iso 1000 when you using full battery (7,4 v and up ) you have less problem but from (7,4- 7,2v ) on iso 1000 start getting more lines .
At 6:12 you talk about the overflow of light to neighbouring pixels. But why does it only leak to neighbouring horizontal pixels and not vertical pixels.
It is related to how rolling shutters work. The sensor is read line by line and there's one set of amplifiers per pixel line and something something. Explained by an engineer friend, but he doesn't specialize in microchips so that's as far as I got.
CMOS sensors streak horizontally… CCD streak vertically
Great job. I haven't seen this happen in any of my shots, but it is as clear as day in your video. I would love to see the next 2 videos you have planned on the GH6.
Good stuff as usual man!!! But do you think it’s the sensor issue, Taft they are unwilling to recall?…. Or jus firmware related?
it is a sensor issue, check ua-cam.com/video/nyFLRSMR3M8/v-deo.html where I explained that it's all CMOS sensors that have that.
@@THEDPJOURNEY so Panasonic would have to replace this?

To me this looks like exetremly rare and un-realistic use-case scenario. I would not even call this "basic high dynamic range shot".
As GH6 owner who never saw this streaking on any of my shots I would be more concerned if Panasonic would actually listen and fix this for all other users who do not deliberately shoot this kind of "artistic" content. Fixes do not come with on/off toggle in settings. We do not know what would be the side effects or price that we would need to pay for doing more drastical fix.
I would much more have Panasonic focus on things that are benefitial for everyday user in properly exposed or real life shots.
In your description I would like to see:
Basic info on what lenses, focal lenghts have you used during testing. What are your settings i.e. exposure metering mode etc.
If you have some real life examples of this streaking ever ruining any real-life shot please include those in the description.
You could have also included waveforms so we can get the idea of how many stops you was overexposed during each setting.
This issue is already fixed now with firmware V1.2 that was recently released.
@@RagingShrimp67 My understanding was that Panasonic made chaanges to minimize the banding already before or in in FW1.0 Seems that the video doesn't say wether the footage was taken before the fix or after. For sure the author of this video expected more agressive mitigation then Panasonic was willing to implement.
@@RagingShrimp67 Panasonic have confirmed the problems. I think concert shooters will be disappointed, and Pannys and M4/3 especially seem popular in that group
Nope, it's exactly the same, Just posted the results in the community tab.
Not sure where you got that information it was fixed from
Have you been able to test Firmware 2.0?
It seems like, that issue does have something to-do with the coatings on the OLPF of glass, which sits in front of the naked Sensor. I remember these things quite well, from my Sony A7. It's coatings caused under special circumstances light reflections interally, which could ruin some pictures.
I wish, this is a common CMOS sensor issue as I mentioned in the episode.
Thank you mate, this is a real camera review. Not very often seen on UA-cam. Good work!
It’s my absolute pleasure. Glad you liked it
Hey Sherif,
Great video my guy. One question though because I am not very technical does the Bayer array have anything to do with this or is it just a design flaw of all CMOS sensors even if we strip away the color filter?
All I know is that it's the CMOS sensor design hat creates those horizontal streaks, bayer is in all CMOS anyway, some have a slightly different pattern than others, but don't think it affects it, CCD sensors create vertical ones BTW.
@@THEDPJOURNEY I was more wondering Bayer vs xtrans but I actually got my answer when I was recording a test shot with my xt-3 where I put a white background on my PC and shot it in a dark room and there was streaking. But I came to the conclusion that there are different types of streaking. There's the light streaking where the streak darkens the area it affects and there's the streak that lightens the area it affects and one is clearly better looking than the other. A streak that comes from a light source that lightens the surrounding could look like an anamorphic lens flare, an unwanted one of course but it is much better than a streak that darkens the area surrounding it which makes no sense from any way you look at it.
Interesting video! Thank you.
Thanks for watching
As usual, you cover issues that either other people dodge or fail to acknowledge. This was an important video for me. Even though I am happy with my Sony A7iv, I was really impressed with the features of the GH6 and thought about getting it as a second camera. But, after seeing this video, I will not even think about buying the GH6 until they fix this issue. So, I'm not sure if it's worthwhile creating more videos until this is fixed. It's like buying a car that stalls every five miles, and you have to call roadside assistance to get moving again. Thanks for your fantastic content. You really provide a great service to the filmmaking community.
Thank you so much for watching and for your support. I always hope that my videos help and educate beyond the typical hype that’s all about reading specs rather than really checking camera’s actual performance.
Thanks again
I had my GH6 for a month now, NEVER had a problem with the horizontal banding, I can hardly notice that. If you are shooting towards a window, you are turning dynamic boost on anyways (actually I use it as default).
@@waynecake5867 Not having encoutered this problem does not mean it doesn't exist. Panasonic confirmed it's there and actually thanked me for pointing it out. You just didn't recreate the perfect scenario and settings that let it manifest that's all. You'll eventually find it, won't be a surprise to you when you do
@@THEDPJOURNEY I do found it, but it didn't bother me.
so what are the ISOs I can shoot with again? Im confused, and sad. I found streaks in night shots, thought it could be from some types of lights...but then I shot daytime outdoors today, and it's all streaked. Iso 250 onwards....
I've just come across this issue in all sorts of lighting conditions, But I quickly realised, this only occurs in 100 and 120fps. I've never seen it in 60fps or lower.
Good insight here. Thanks for sharing!
Cheers Kevin
another amazing review --- extremely useful. -- THANK YOU!!!!!
Glad it was helpful!
I don't get why some take it as acceptable being "It happens at certain ISOs during certain lighting occasions". From what i see, BMCC 6K FF suffers the same streaking. Not sure if the newly shipped Pyxis having the same phenomenon. Hope i could see that & bmcc ff being reviewed mainly on this streaking issue as well.
Great video. Thank you. How did you make the transition at 3:55 ? Can you screenshot/share the adjustment layer settings or, if you didn't make it from scratch, share where you got it from? Very subtle and beautiful.
Excellent analysis Sherif! I’m glad someone is taking an objective view on the issue
Thanks Ihab
as always great video!
Cheers thanks
Great video! And just before I thought this is the one camera for me..... now it's honestly not as sure choice :/ Do you think there is any other one that can give us as quality and features in this price level now? A7IV, Pocket 6k Pro, Z-cam? Only for video... no need photography features.
Unfortunately I can’t find anything. Panasonic did create an awesome camera on paper! FULL of great features! But messed up the most important component
Bought the GH6 a month or two ago. Because of this issue, I can’t use it for professional work and can’t return it. I’m stuck.
Sorry to hear that Matt, maybe they'll fix it... who knows
How is it with all the problems now?? 6 months later now..thanks for the video
Thank you for this in depth review!
My pleasure, glad it was helpful
hello Sherif, interesting tests, while you was conducting these, did you encounter even the sensor stitching issue of the V-Raptor (producing a vertical line in the center of the frame) or did RED somehow fixed it?
I honestly didn’t notice it. I own the raptor and already had several commercial shoots with it. I’m also aware of the problem, but couldn’t replicate it
Very well done review! Thanks for the information on the GH6. Somewhat concerning for a flagship m4/3 camera. Is this a firmware/profiling issue or sensor hw issue?
this is a HW issue as mentioned across all CMOS sensors. But that can potentially be mitigated to a certain degree with FW. As of now, it's still there.
Thank You for honesty ✅ I own several Panasonic cameras with the GH5M2 being the most recent. I was hoping for a lot more from the GH6 and will wait until the GH6S or GH7 to see if these lingering problems still exist? New subscriber here 👍🏻 Cheers from Western Australia 🇦🇺
Thank you so much for your support and welcome aboard
I'm on the latest firmware update on my GH6 cameras. I mainly shoot weddings and half the time the getting ready is in a dark hotel room with outdoor light coming through the windows. I absolutely hate the challenges of having to shoot different for a lot of those scenarios because the streaking comes flying in at full effect with dark rooms and the subject right up against a super bright window. Very frustrating.
I know! That’s why I have that video as a warning for everyone
Thanks for this information and dude your videos are amazing. Where do you get the different cameras images you use in your videos from?
Thanks for the compliments, I own those cameras I used int he video
Can I ask you for an opinion? to film 4k DCI do you think that the quality of the GH6 far exceeds the GH5??? Is it worth changing from the GH5 to the GH6? They tell me that the GH have noise problems in the image and autofocus...???
The full V-Log they have in the camera renders a more accurate color and highlight roll-off yes. Not sure what they mean by noise, and yes, focus is still a problem
@@THEDPJOURNEY Well...thats not what I ask but thanks
I had this issue on my RED Helium 8K sensor, one of the reasons I sold it. Also saw this on the Canon C300 MK II, which made that camera unusable.
I'd like to know more about your experience with this problem. I have certainly seen others complain of this on their Canon C300's too. Can you go into more detail? RED Helium too? Hmmm
Seems the M43 GH6 is such junk, confirmed by the streaking issue, it is not worth DP Journeys' time, hence the "THE PROBLEM with GH6 and why I didn’t review it" title.
@@peternavanac9310 As a Lumix S1H and Sony A7-IV, A7S-III and Sony FX6 owner....I can absolutely say the GH6 is not "junk" at all. Not even close. The overall image quality in most cases is literally superb.
@@clifftotten7609 That was the point of my comment. Thanks for your reply. I too find the image quality to be simply superb...with or without the "problem" found by DP Journey.
I never said it was Junk and not worth my time.
I said “It’s an awesome camera” in this episode. And it didn’t make sense to review that awesomeness before I talk about that issue first. Which could be a deal breaker for some people, me being one of them.
So good to see a video from you man! It’s been a while. But it’s been a while since I’ve uploaded one too so I get it. Side note: If you ever need help testing all those cameras let me know 🤣 I can definitely make time for that 😃
Has the latest firmware fixed this issue or does it still exist?
Nope… it’s still there
That streaking looks horrible. As a previous GH5 shooter, I am glad that I went with the S5 instead.
Do you plan to cover the A7IV? It looks interesting but with some flaws.
Same here, I went from the GH5 to the S5 instead of the gh6 and saved 800 bucks. S5 is a beast and I don't need any more than that!
@@looklook5766 Everyday I'm blown away with the quality of image from my S5. Recently in the UK, you could get a brand new S5 + 20-60 + 50 1.8 for £1299.99. Insane! Wish it had a full size HDMI, but you can't have everything I guess :)
Glad you're back. At $2k the Blackmagic 6k (with a polarizer for this "fix") is still killing it for me. Would I like to have the FX3? Of course but that isn't in the cards....yet.
Great Review, this is the stuff we need to know! imagine having those streaks show up in a pro shoot: Not acceptable! I'll keep watching to see if the Panasonic gets this fixed...amazing camera from what I can see, but an issue like that would keep me from using it on a professional shoot.
Yeah, exactly what I thought! Thanks for sharing your opinion
I bought a new GH6 yesterday on the proviso from the store that I could return it if I came across the streaking issue. The cam is loaded with firmware 2.2. I recreated the streak in about 20 seconds. Shooting a light source with a dark background it appeared immediately. I do a lot of event filming so lots of light in dark rooms so there's not a chance I could rely on this camera with client work. Maybe that's why it was so cheap too? I got the cam, the 12-35 f2.8, a spare battery and a 128gb CF express card for £1700. Kinda thought that price was too good to be true. This fault is unfortunately pretty bad rendering this camera poor and useless for client work. Pretty gutted about it. Loved the GH5 so was hoping for this to be another solid workhorse.
Same feeling I got… was so looking forward to it
Did you actually watch my video before you bought it?
@@THEDPJOURNEY I did. It was because of your film I was cautious and got the store to guarantee I could bring it back if I found the issue. I had seen lots of people on the forums saying their's were fine and the firmware had eliminated it so wondered if it could be down to the individual camera but having seen it for myself I think the sensor is compromised and those people that haven't experienced it have just been lucky. It's there and it's pretty bad - completely unusable for my client work. I can't see how firmware can solve it. It looks like a hardware issue to me. My advise to anyone wanting to use this cam for professional work would be to avoid it big time unfortunately.
Technically it is fixable, but this sensor seems to have it at a very high level that it becomes hard to eliminate completely. Or maybe it’ll just take so much resources for them to fix which is not worth it.. who knows… shame since the camera packs so much awesomeness. Like buying a Ferrari with a faulty engine
@@THEDPJOURNEY Absolutely! The specs for anamorphic and raw are amazing and the amount of codec options. It's why I took the gamble even knowing the issue, hoping the firmware had limited the effect but 2.2 is still no better really which is concerning. I would have thought this would be a priority. I took it back today and exchanged it for S5IIX when it comes out. A whole new mount eco system to adjust too but that camera also looks seriously impressive!
Do you feel that this issue is a noticeable deal breaker in the Panasonic S line?
Didn’t check on the S, but it’s a HUGE deal breaker for me personally on the GH
The Question is, who is filming a scene like that? :)
Check all indoor scenes in all Hollywood films. The list is endless.
That’s not the point after all. If you find yourself in this situation with this camera. Then you won’t be happy with the result.
Any Wedding videographer with the bride entering a dark church at 1pm summer wedding...
Exactly.
Great information, thank you.
Cheers
I don’t really understand what you are trying to say here. You’ve reviewed a lot of cameras and they nearly all have them apart from the $30,000 red camera. We’re talking about a very different price point camera here and there are obvious jobs for this camera. Your light streaks will appear if you use no lighting at all in my opinion so I would never shoot the way you’ve shown in this example. The comment about your clients will complain about your shots will not be because of the camera it will be because you didn’t use professional equipment such as lighting. I don’t think this is a very good review and telling people not to buy this camera based on the light streaks.
You can work as cinematographer also with a 2.000$ camera...and if you work as cinematographer, you play a lot with contrasty scenes. You can't deliver material with this big issues to your clients (creative agencies, final deliverables, etc...)
At the launch of the gh6, youtube was full of videos with the problem of the light streakes...if you didn't see them, it doesn't mean that other people will not see the problem.
I kind of thought this too...I mean I want the issue fixed, but no one here can honestly say that the shot as set up would be one they would take.
First: I compared it to the GH5 as well which is cheaper and performed better. I just tossed In the RED literally because Panasonic told me all cameras express this streak, even RED. Because they know I own it.
Second: no idea how will I shoot with no lighting?! Unless you mean not directed into the sensor? In that case when everything is very midtown with very diffused light, then probably you won’t notice the streak. But do you wanna be limited to that? Cameras are here to give you the freedom of shooting whatever you want, not to restrict your creativity.
Third: can you please define professional equipment? That’s so irrelevant man. A light source whether it’s the sun or artificial light, they all fall under “light source” the sensor doesn’t differentiate. It’s just a silicone layer that’s sensitive to photons
Lastly: I never said “telling people not to buy the camera” I said “I will not buy it” you do whatever you like. If you like it, then buy it. I’m not here to tell you what to do, I’m only reporting what I saw and telling you that even Panasonic admit it has light streak… even when using “professional light”
@@THEDPJOURNEY I really appreciate all of your videos and especially this one, even though it’s not awesome for me as a GH6 owner. If anything it may put pressure on Panasonic to fix it. Thank you so much for this.
Yeah I was pretty disappointed as well. But let’s see, maybe they’ll fix it or at least improve it
