Never thought I’d be watching so many Sony camera videos! So much still to learn.
Who would have thought you would buy a Sony camera?!?
Thank you taking the time to explain all this! It's much easier to understand than simply reading or hearing it explained without examples.
You are very welcome. Thanks for watching!
Josh, you really know your stuff man. Thank you. What I love about videos like this is, they provide answers which then allow me to think about other (preferably creative) things. In other words, while I'm shooting, instead of going back-and-forth on what I THINK are the tradeoffs associated with a given setup, I can move forward KNOWING the tradeoffs. Thanks again.
You are very welcome. Glad the video was helpful for you. Thanks for watching!
Been traversing all of your A74 content now that I finally got one in hand! Loving all of it! I've been playing with using the digital zoom mode in camera instead of clear image zoom. I feel like digital zoom gives you a similar result to just cropping in post, which is nice because you retain the noise performance of the full-frame image. The clear image zoom is downsampling whatever portion of the sensor you're using, which is excellent, but you're oversampling a lot less than 7k as you zoom in, so the noise removal seems to deprecate. Another benefit to using digital zoom is you can go up to 4x in 4k. Because of the 7k oversample, 4k at 4x digital zoom looks surprisingly excellent, and the noise seems less than with clear image zoom. Have you messed with the digital zoom at all? I know it sounds like the worse option, but I'm really impressed!
Excellent. Thanks for answering some of the questions I’ve never asked :)
You're welcome. Thanks for watching!
But! If you crop in post you'll be stretching 4K footage to fit a 4K timeline eventually losing sharpness, or benefit a little from oversampling when fitting an FHD timeline. On the other hand if you shoot in crop mode you get 4K footage out of camera, which you dont have to stretch further to fit the 4K timeline, and you benefit immensely if you downscale to 2K or FHD timeline! So Id say cropping in camera allows more flexibility in post... this approach works well for anamorphic footage.
Surprised to see that clear zoom is acually useful and not just a marketing term for variable crop factor XDD
Great job of comparing all the modes! Thank you!
Useful tutorial. Thx brother‼️
You’re welcome. Thanks for watching!
You've made a lot of great videos.Thank you very much for explaining the details I want to know in detail
You are very welcome. Thanks for watching the videos!
.
Tons of great info! Thank you! 🙌🏻🙏🏻
On the new firmware update for the FX6 Clear Image Zoom has AF and AF Tracking and I love it. It's the first camera that has this and i hope Sony puts it in all of the cameras. Great video
I hope so too. I don't see why they can't add it.
Nice research, this helped out a lot, thanks Josh
What a great video. Thank you so much. I am shooting the A7Rv and have been experimenting with the Clear Image Zoom. I noted that you can't use Clear Image Zoom with RAW in stills so I was forced to go to Jpeg. This is not a problem if your product will go to the internet, but is not (for me) acceptable for print production. I do like having the Clear Image Zoom option available to me but with your video, I have a better understanding of the advantages and disadvantages of using it and using crop mode. Thanks again!
Great video! Sometimes subject too far for eye detection, that is where I am turning ON crop mode where the eye is closer for focus system to recognize it.
Great comparison & summary, thanks.
You're welcome. Thanks for watching!
This is really well done. Answered all my questions, and then some. L&S Thanks.
You're welcome. Thanks for watching and for the support!
Very interesting. Great video. Thanks for sharing.
Cheers from LA
You're welcome. Thanks for watching!
It's precious! Thanks bro!
You're welcome. Thanks for watching!
Thanks for the detailed comparison
You're welcome. Thanks for watching!
Great video explaining this, to me it has always been black magic too but it’s good to know what we can do with it!
Thanks for a really helpful video
You're welcome. Thanks for watching!
Face/eye auto focus works with clear image zoom in the latest FX6 firmware update, so hopefully that will come to other Sony cameras soon! Thanks for putting this video together. Very helpful and interesting 😉👍
Oh nice! That new FX6 firmware update looks awesome! I am hoping that the autofocus stuff and focus breathing compensation gets added to the FX3/A7SIII ASAP.
@@Josh_Sattin me too! The breathing compensation is awesome.
We need it now!!! I will be able to buy and use all sony lenses for video without worrying of fb
Agreed! I have been enjoying it on the A74.
Very good one! Thanks! Just subscribed
You're welcome. Thanks for watching and for the support!
that was really helpfull, thank you!!
You're welcome. Thanks for watching!
Great video! I was wondering how well crop mode and focus breathing on is doing for bird photography (my main requirement) - sony A7IV combined with the 200-600 lens is the rig I envision. I would say that the auto focus will be still excellent but what about the ISO noise? Up to which ISO crop mode is usable?
Thank you for reminding me of this feature!!
You're welcome. Thanks for watching!
Great work subbed
Thanks!
Thank you extremely helpful❤
You're welcome. Thanks for watching!
This was useful, thank you. Confirms my decision to get the A7CII over the IV since it has all of the AF features intact in CIZ (along with LUT support, AI, etc.). It's also satisfying hearing others talk about hacks for added reach lol. My wonkiest is using 4K30fps mode on the A7III with the APS-C Sigma 16mm in full frame mode because the 1.2x crop is just enough to remove the vignetting, giving you a 19mm lens for video with extra detail over the Super 35mm 24mm lol.
Interesting test, thank you for posting it. I wonder how these modes compare as far as moire and other artifacts go. Do you have any thoughts on that?
Sony Clear Image Zoom is actually a function of the sensor readout. Sony developed a live, "sliding" sensor read crop. It's not exactly a "zoom"...its really a dynamically crop that opens and closes as it does it's sensor readout. The A/D converters are processing the raw RGGB scaling and it outputs the raw sensor data in 4k. This way, the image processor does not have to do any of that work. Using Clear Image Zoom in full frame at 1.5x crops to to an APS-C sensor read. Doing it in APS-C puts the read into MFT sensor territory. So yeah...its a dynamically changing, live moving sensor crop done on chip.
I am more confused. But the it need to have that pixel to work with? A7sIII only have 12mp, but it can still use clear image zoom to simulate apsc mode.. and the result again is similar to full frame mode. But how do sony do that. There is no extra pixel for a7sIII to zoom in while doing clear image zoom.
Thank you!
Respect from Africa 🇿🇦
Is CIZ for movie mode only? Can it be used for RAW stills? Love your teaching style Josh…..
SO helpful dude to a noob (and clearly even experienced owners didn’t know a lot of this). Here’s what I was thinking of doing for my first lens:
For my close up product review videos, I’m going to upgrade from my iPhone 13 Pro but want to keep the perspective the same. My table is only 1 size. Also need this for live streaming and future talking heads. So I’ve decided on Sony a7iv.
I might end up needing 24-28mm range so I was considering the Sigma 16-28 HOWEVER I LOVE the look and focus speed of Sony glass. So I was planning on just getting Sony 20mm G and using clear image zoom to get to 24-28 if needed.
But after watching your video I’m not sure that’s the best route. Although they say zoom lenses are not as sharp. I want the sharpness. I guess it’s just a tug of war between a Sigma zooming in that’s not as sharp to begin with, vs a sharp Sony losing sharpness due to cropping in. I really can’t afford noise though. But if we are only talking 20-28mm would it really add noise? Not to mention I will be in a studio so I can supply lighting as needed.
I dunno man. What do you think of all this? I would love any input. You sound like you really know your stuff.
I was under the impression that since we have a 7k sensor, the camera downsamples to 4k anyway, so it wouldn’t make a single difference if we were cropped or not cuz it’s all going down to 4k. Maybe that’s not quite accurate info though.
Aps-c mode does change the quality in a7r cameras. Edit your clip. Very nice and helpful vid btw ✌🏻
Is there a difference in rolling shutter between CIZ and crop mode?
Sorry for all the questions you just seem very knowledgeable but I wanted to ask ur opinion on something. So I have canon Sigma Aspc Glass (18-35f1.8 & 50-100 f1.8. And I’m looking to get an A7IV Do you think I would be able to use my aspc glass with an MC-11 adapter On the A7IV for a brief time until I can sell the aspc glass to put down on proper 24-70f2.8 sony glass? Mainly for hybrid shooting. Would love to hear ur thoughts
After a long session with Sony help people, finally did a factory reset and all came good with all my lenses. We are not sure why, as all firmware was up to date. Just have the pain of rebuilding all my customisation. Pleased to have the feature working though.🤗
Would you know if I am using a Sony a1 - with the Sony 200-600 with a 1.4 TC, in crop mode, in clear image zoom mode - why I can take photos but not video?
did the clear image zoom only available for all sony lens or only for some type sony lens ?
i should watch this video before, because when i shoot a video with my sony lens 28mm f 2.0 and use apsc mode its loosing much quality.
I think clear image zoom maybe changes position of sensor? Not sure
Very thorough, strait the point and informative. Thanks for the video!
You’re welcome. Thanks for watching!
Amazing video! Finally something clear about this matter. Only need to know if you can use clear image zoom in 4K@60fps which uses crop mode by default?
Yes a clear image zoom of 1.5x is possible on 4k60, just tested it on my A7IV. Not a 2x like in photo mode but at least 1.5x.
@@NaturMV Thanks!🙏
@@Bo_Hazem You‘re welcome 😊
Hi Josh, just discovered your hints on button setting, as I wanted to map Clear Image Zoom. I have the 24-70, but it is the new GM ii version. When selecting CIZ, I get a message 'invalid with this lens'!! A new lens, but it loses that feature? Will contact Sony.
Interesting, when use clear image zoom on a6700 or fx30 the video looks very noisy, it looked ok on the tiny screen but when throw it into editing it was full of noise specially the darker and night scenes I shot. It’s a good feature but I would say for emergency or home use not for professional work. Thanks for the results I taught there was something wrong my cameras lol
I have the sony 85mm f1.8 and it says this is invalid with this lens..is there a way u can find out which lenses can do it thanks
Excellent, informative video.
Sadly, the most important takeaway is that the A7IV produces severely degraded quality in 4K60 / 4K50, where crop mode is enabled.
Does 1080 60 look better?
Haha I was about to do a video on this this afternoon!
Interesting about the noise, I wonder if there's just more noise reduction going on with clear image zoom v crop.
One thing I was going to test was rolling shutter, and whether it's better in crop. Also if HD is better quality in crop v full frame which I found was quite soft.
The noise in crop mode has to do with it reading out from a small sensor. Please check out my video that I mentioned about crop sensors. I don't think there is any additional noise reduction going on with clear image zoom because the noise looks similar when using clear image zoom vs zooming in post.

will this be the same for a7s2, a7iii ?
Did you not turn up the responsiveness of the AF? It was unusually slow in your example.
Thank you sir... my 35mm turns 50mm hehe! It is ok in photos in events some clients only posted their pics in social medias and 4r to 8r size printing even inbig size prints God Bless!
Hi, thanks for the comparison. Can you use crop/apsc mode while shooting 4k60 or is this only for 4k24/30? . On my A7iii I have a custom button set to apsc/full frame switch so i could quickly tap it for extra reach. I wanted to know if I could do thesame on an A7iv while its in 4k60. Thank you
In case you haven't figured it out already, you cannot use crop mode when doing 4k60 since shooting 4k60 already requires a 1.5 crop. If you try, you get an error that says "This operation or setting is not available" and lists 60fps as the reason
If i shoot in 1080p on crop mode then will the resolution be 720p???
does clear image zoom work at 4k 120 fps ?
Mine doesn’t work with AF continuous mode, do u know why ?
The comparison, I needed...great video! I have been thinking what 20mm-ish budget lens should I buy for Vlogging and Travel videos on my FX3 and A7IV. This video just kind of take the APSC lens ideas I have completely out go my list... I was originally thinking to get either a Sony 11mm f1.8 or a Viltrox 13mm f1.4 and use it in crop mode for video. Unfortunately none of these lenses would be good for photos (astro) since the crop mode in photo drops the quality to 14mp (A7IV). So now I am back where I started my shopping cart and I am looking at the Sony 20mm f1.8 or the Viltrox 24mm F1.8 for only $379!!! I own the Sony GM 16-35 f2.8 which is one of my favorite, but its more like a video project beast not a vlogging/walk around lens on a trip since its heavy. What would be your suggestion Josh for 20-24mm? I also own the Sony GM 35 f1.4 so I don't think so I would get a 24 GM.
I personally like 20mm on a full frame camera a lot for vlogging and filming myself. I tend to just use a wide zoom (16-35) most of the time, but if I were to get a smaller, lighter, wide prime lens for Sony full frame, I would get the 20mm 1.8.
still No eye tracking while clear image zoom? no updated?
My takeaway is Clear Image Zoom > Crop Mode. Easily. Also, CIZ = Zoom in Post. Wow. Didn't expect that.
Clear image zoom only works in jpeg & not in raw?
Hey Josh, thanks a lot to share your spectacular video. I hope I can ask you a question. I have to buy a new camera to make documentaries in 4K. I will always use it when traveling to document the traditions of indigenous peoples around the world. I like shooting in 4K 50p. Honestly I don't do slow motion, in your opinion is it better that I change method and shoot my documentaries in 4K 25p, or is it better to change this Sony camera with another one? I will use only one lens, that is Sony 24-105mm f/4 G OSS. What is your thought? I don't want to spend more money than what I pay for the Sony camera. I thank you.
Hey there. I have responded to your questions about camera gear in the comments of other videos. If you are set on filming it 4K50 and want a mirrorless camera then I would recommend the Sony FX3 or A7SIII. The 24-105mm is a very versatile lens in terms of focal length and having OSS.
@@Josh_Sattin yes, I remember, but maybe you missed reading my last line of my post. Anyway I thank you.
Can you set a shortcut to a specific number using clear image zoom? For example, if I want C3 to be set at 1.2 could I do that? Or do I always have to use the zoom scale.
you can
Not available in photography mode if set to raw.
🙏
So, basically you are shooting still images while you on movie mode? To take advantage of the clear image zoom? Would love to understand that from your vid (a suggestion)
The images that I show in this video are video clips, not photos.
Very interesting video. However as all the images in this test were jpg....... In your opinion is there any difference to image quality to be had showing in RAW? While crop mode is possible in RAW clear image zoom is not....which is a real pity, How would a jpg shot with CIZ and crop mode compare to a RAW shot in crop mode and resized using some AI method in post.It may be splitting hair but it would be interesting to know your thoughts.
Everything I showed was video, not photos.
I need a table to show all the pros/cons for each of these. too much info :P
Although crop-mode and CIZ might not affect exposure when the exposure triangle is locked-off in manual mode, wouldn't crop-mode, at least, affect the light metering if, say, I were to be shooting photos in Aperture priority with crop mode? 🤔
Sensor size does not effect exposure. Exposure is determined by aperture, ISO and shutter speed. Check out this video where I cover everything about crop sensors: ua-cam.com/video/Qcdtq3N6yQI/v-deo.html
@@Josh_Sattin To clarify, in my original comment, I did not say that sensor size/crop affected exposure. My question was about metering calculations
Sensor size or crop mode will not effect the exposure. When you use crop mode, the things that effect the exposure (ISO, shutter speed and aperture) do not change. The camera will still meter the exposure the same way. Please check out this video. It will answer your questions: ua-cam.com/video/Qcdtq3N6yQI/v-deo.html
Thanks for watching!
on my sony a9ii I've been trying to figure out how to enable the zoom settings via custom key assignment but the zoom function is disabled. any hints on how to enable the clear image zoom?
I have the same on my A7Cii. Did you figure it out?
I got "Invalid with this lens" error when use CIZ for both Tamron 28-75 G2 and Tamron 50-400 on A7iv body ( latest firmware on both body and lens )
Any idea to resolve it evr1 ?
You might need to use a Sony brand lens. Not sure though.
Oh WOW. All these lens reviews and comments you see say “But you can just use Super 35 mode and now you basically have a 50mm lens”. Doesn’t seem to be the case does it? I know we are pixel peeping but I mean when you’re cropping in at parts in post like I do, it’s gonna be important.
So wait, when using 4k 60, its crops then on top of that can u use super 35? plus clear image zoom?
4k60 on Sony A7IV automatically uses Super 35. So u can just add clear image zoom on that. If you use active stabilization it will ad another like 1.1x or 1.2x crop.
I just tried this CIZ on my a7 IV. First it has to be in JPEG. Fine. Switched to JPEG. Then it says it’s incompatible with my sigma 24-70 2.8. Bummer.
Hi. What about Crop mode for still images?. How many mega pixels does shoot in while in Dx mode?.
I think it would be around 14.67 megapixels in crop mode. It is a 1.5x crop so full frame would be 2.25x the area.
33 / 2.25 = 14.67
@@Josh_Sattin Thanks so much ☺️🙏
CIZ is amazing
Dear Josh what is the zoom factor of the Sony A7IV? X 2 or X 1.5?
I'm not Josh, but do you mean Clear Image Zoom? It seems it's 2x for photo and 1.5x for video.
@@NaturMV Yes yes clear image zoom. I bought the camera and find it very useful to zoom, almost without loss of quality (with jpg only)
can I combine clear image zoom with optical zoom? can i use them together? ☺
Yes, one doesnt affect the other.
crop has a bit faster readout speed, if you want to reduce the rolling shutter effect. just as an another factor in favor of crop mode.
also did few tests of my own and concluded that digital zoom is not worth using beyond clear image zoom as opposed to zooming-in in post. that would be at 4k60 crop mode with active stabe on. would you concur?
im trying just get as much reach from my lens as possible. Also i found out that there ar no benefit in using FHD with digital zoom as opposed to 4k+ clear image zoom + zooming-in in post.
I wish sony would just give a "zoom" feature that would go seamlessi from 1x no crop to crop+ clearimage zoom. and also a setting with 1:1 readout at 4k and fhd. that would just eliminate all the questions... and its firmware doable. also raw video at 1:1. lol.
Could you give a number on how much reduced the rolling shutter is when using crop mode? I don't seem to find this info anywhere! Thanks!
Why does crop mode have more noise? I don't know the technical explanation.
ua-cam.com/video/Qcdtq3N6yQI/v-deo.html
@@Josh_Sattin I meant crop mode in the FF matrix
I don't get it. Why would you be using those various "magnifying" options on a wide field of view, when you could just zoom in optically. One USES those options when one needs to "zoom" in further than your longest focal length. For instance Birding/Wildlife with a longer lens, when one needs to get in tighter. There ... since one has to use Jpegs to get Clear zoom ... the big negative is loss of fine detail ... say in Bird feathers. Jpegs typically smear that very fine detail, making the Clear option less than useful. I AM looking forward to trying it out with my 500, in Crop mode, plus Clear Zoom, with my Sony A1 ...
thank u👍
You're welcome. Thanks for watching!
late to the party....can I ask why you chose Slog3?
More dynamic range and control over the image.
Obviously Sony Holding Back on a lot on Tech.....Ie Soft
ware Based!
Alot said, however I do not see any major difference in all of these settings until you start pixel peeping, so I guess your investigation was thorough, however reveals no real objective difference between all of the settings, unless you have microscopic superman vision. In that case alot of these settings being added to the sony menues really adds nothing to the cameras ability to take photos, but would add so many pages to the camera manual that it would be cost prohibitive to add one in the box with the cameras when purchased.... oh, thats right, they don't included physical manuals anymore do they...
Sony calls it a tool box, not a briefcase or suitcase.
4k 60 crop quality made sell this camera.😕
Is that a paper back drop?
Yup!
@@Josh_Sattin looks so good! I’m converting my garage into a studio & gathering ideas. I just bought an A74 & A7C for compact. I have the gear, now I need to learn how to use it lol
