@@cineffect Then it would be correct to say that MFT is more than enough for you. Other users will prefer cameras with a larger sensor or limit themselves to the iPhone. But to categorically claim that the sensor size does not matter is not true and does not correspond to the situation that has developed in the camera market.
We went through a lot of versions of MFT to get to the GH7. I’ve traded up since shooting multiple GH5 for Events. You are correct I moved to FF due to lowlight issues when shooting Weddings Venues. Once you move to Full Frame the MFT lens collection has to move with it. I wish I could buy the GH7 but it wouldn’t make sense with my Full Frame Investment. I just commend LUMIX for having both tracks for us.

Aperture on an MFT is correct double the Aperture of a FF in relation to debt of field. Not in relation to light. So an MFT 1.4 lens let in as much as light as an FF 1.4 lens.
This is correct, but a full-frame sensor does gather more *total* light due to its larger area. This leads to lower total noise and therefore better low-light performance, I think mostly due to the fact that for a given resolution, the individual pixels would be physically larger, and have a larger “full-well capacity” of photons/electrons, which improves signal to noise ratio.
@@johngwheelersensor light gathering ability has many factors affecting its performance and could be the same for different size sensors but it has nothing to do with the amount of light a lens lets in.
Exactly Joost, so many people think "smaller sensor so less light", which is factually true but that doesn't mean you have to multiply the aperture by 2 as well.
The G9 II and GH7 are excellent. The lenses available are amazing and second hand can be very cheap. I have mainly primes (seven) with f1.7 and f1.8 apertures which I bought for an average of US$100. I got luck at an auction. But even at $200 they are a fraction of the cost new FF lenses.
Loved this. I went from GH4 & 5Dii (couldn’t decide so this was my “hybrid” setup to Sony A7S, currently and for last few years on a A7Riii. I still have a huge soft spot for LUMIX and the GH range, so I find myself thinking about heading back, but as I film either landscape/birdlife and then on the road musician stuff involving low light at times, I’m torn as whether to be sensible given my glass investment and stay with Sony or go LUMIX full frame or M43 with all the reacquisition that will entail. Nice problem to have, I suppose, given what you say about how great cameras are right now. Thanks for this video.
As a very long time MFT user, Panasonic to be exact, I love micro 4/3. I recently purchased one of Panasonic full frame cameras, and I would like to respectfully disagree. Sensor size does matter if even just a little bit. There’s a major difference in depth of field control and low light capability. I think a more fitting title for this video should’ve been sensor size doesn’t matter as much as people make it sound. That having been said, your video is beautiful and I’m a proud new subscriber.
Sensor size only matters when it matters. Honestly I could get comparable results on any of the 3 major sensor size formats but each has their own unique strengths and weaknesses. For wildlife photography there isn't one sensor size that can achieve everything I want - they are all flawed in a few ways so I just chose what was less flawed for me.
Yeah agreed, sensor size does matter but not in a negative way, it matters in a way that they all have pros and cons and understanding them is key. I love my m4/3 for wildlife due to the shooting experience, which as more of a hobbiest wildlife photographer that is so much more important to me than the final image quality, which on M4/3 can still be stellar. I also love my M4/3 for more travel/ adventure photography. However for wedding and client work I stick to full frame because of the ease of use in uncontrollable lighting scenarios FF is just more versatile. I still occasionally use M4/3 for client work, such as when I do truck and car related videos as it has less rolling shutter than my 4/3 camera and sometimes Ff for personal work when I feel like that slight bump on image quality. They’re all have flaws and it’s using them in their best scenarios that’s the secret.
Speaking about low light, I would like to shed some light on the "old" GH5s (basically a GH5 for low light). What still sets the GH5s apart from many other cameras (no matter if MFT or FF) is that it keeps its dynamic range across the full ISO range. Might be helpful for someone, who knows. Check out the review on digital camera world for more info.
« If you are shooting at f4 you were effectively shooting at f8 on a full frame equivalent » : in fact, F4 is f4 on both systems. The equivalent is **only** about DOF. Light measuring remains the same.
The deeper depth of field is an advantage in many situations. And one huge feature of micro 4/3 is the availability of the Lumix / Leica 10-25mm and 25-50mm f/1.7 zoom lenses. No other lenses for any format can match their capabilities.
I have a A7R5 that I use for social media content. I do like the idea of buying a S9 just for some stabilised clips. I'd love it if Panasonic put a M4/3 sensor in a S9 body just for the stabilisation. It wouldn't need to be full spec, as I only shoot 1080 vertical at 50 or 100 FPS. I'd definitely buy that just as a second camera. Your comments on gimbal are exactly my feelings, so anything that can get me a bit of smooth movement would be e big help.
I think the colors from the GH7 and G9II are better than the S5II, but not as good as the GH6. And about the GH7 feeling softer than the S5II, if the GH7 has the same image than the G9II, the GH7 has significantly better details than the S5II (at least in good light) with less edge sharpening. But you should shoot in 5,7k on the GH7 and 6k on the S5II only if you want the best image because in 4k, both cameras seem to have slightly lower resolution than 4K and slightly more sharpening.
Every single UA-camr reviewing the G9ii/GH7: "M4/3 isn't dead, it's amazing, sensor size doesn't matter." Also every single UA-camr reviewing the G9ii/GH7: "In the end, I'm sticking with the full frame S5ii/S5iix." I'm going to go with what people use instead of what they try to sell you. 😜
Sensor size has always mattered, whether or not a given person feel that isn't important or not to them, well that's an entirely different discussion. That hardly does not mean the GH7 isn't going to be a great camera for those that need what it delivers on.
It's not true that camera for video and low light doesn't truly matter, because scenes most of the time will be well lit. You're assuming directed movies, but it's only a fraction of creation, when often videography includes art in spaces where you have no control over light, many kinds of documentary where light creates less informal atmosphere therefore you loose natural way of human behavior, or weddings which you mentioned, or festival/concerts/events recording, where you have no control over light too (me shooting concerts), just to mention a few. So I think saying that for videography low light performance is not crucial just misses the point in my opinion, because there are many kinds of videography where control over lights is either limited or nonexistent entirely. I'd really prefer to have GH7 with all of its functionality, but chosen s5iix just because of low light performance.
@@michaelbell75 I know but smartphones usually have a ton of post processing and over sharpening. MFT cameras still have a much bigger sensor. Though, Apple Log can look pretty impressive.
I don't believe your presumption is accurate, in thinking GH7 would be inadequate for low light shooting, in environments where lighting control is impossible such as wedding events. The new Micro Four-thirds sensors are quite sensitive in low light compared to those from 5 years or more ago. I'm finding GH6 beautifully performing with truly negligible noise in this regard. Moreover, you'll get shockingly good handheld results with Lumix GH6, GH7 while filming a passing car or shooting real estate videos. Seriously -- with the appropriate settings [and perhaps with E-stabilization for additional steadiness (at the expense of some cropping) you could indeed get away with no use of a gimbal. Another advantage of MFT worthy of mentioning is GH6/GH7's huge array of professional ultra high bitrate CODEC options even up to 800MBPS easily provided the user, over comparably priced FF cameras -- and shooting video therewith, confidently with virtually no worry of overheating. Really decent video notwithstanding those little technical discrepancies. Subbed!
Say this more often, so Panasonic could make MFT for 4000 USD and call it better than full frame.....say this often too so iPhone could charge 2000 USD for 1 inch sensor 😂😂😂😂
s5iix - full frame with better low light n better image quality but with shitty rolling shutter n crazy 1.5x cropping for 4k60 video, add e-stablization and u end up with 1.65 & 2.1x crop. Other than low light and image quality, GH7 wins in almost every aspect. GH7 is too big for a m43, personally i will be waiting for a full frame version of GH7.
Sadly it does 😢 the saddest thing is that everyone stopped making mft lenses. Ff glass is also super affordable where some are even more affordable than mft glasses if you are going for something comparable in terms of fov and aperture 😊 also physics can't be hacked. Talking as a former mft user, i think if you are shooting a narrative, you can go with mft but if you shoot in all kinds of situations ff is the way. Even in your test, we can see how mft is more contrasty vs ff as we have less light in the shadows. Seriously the new s1h ii will be insane as it will surely have all these features
The sensor is different or at least modified to accommodate PDAF. Reviewers observe that: the colours out of the GH6 are more appealing (warmer mid tones); and the dynamic range and noise much better on the GH7 and G9II especially at lower ISOs as the dynamic boost is basically always ‘on’. The GH6 is still very good and if you don’t need PDAF then it can be had for a bargain in some countries as it is being priced to clear the remaining stock (about US$1200).
