Follow up on the test result, I did another test and increased the exposure in post processing, and confirmed A7cii s-log3 does have second base ISO at 3200: ua-cam.com/video/A5f0mgegeBg/v-deo.html
did sony fixed this in new firmware update?
This is THE ONLY VIDEO COVERING THIS ON ALL OF UA-cam.
I've been asked many times about this issue. Hope you find it helpful!
Thank you for this video, i have been searching to find a video that will shot the a7cii at night, and you delivered!
I'm glad it helped! Thanks for supporting!
that was the same case with the a7s III and A7 IV (both the same sensors). the special feature of the a7s III/ZV-E1 is the second native iso with 12800 and almost no loss of dynamic range. And of course the noise appears finer on a 33mp sensor.
But I'm still surprised that I don't see any improvement at iso3200
Great, but i would push that iso a little bit harder to see the bigger number 😊😊
Here's a follow-up video, I did another test and increased the exposure in post processing, and confirmed A7cii s-log3 does have second base ISO at 3200: ua-cam.com/video/A5f0mgegeBg/v-deo.html
I was doing similar tests with my A7C II and I totally agree with you, it seems there is no 2nd base ISO at ISO 3200 on SLog3 (despite what other sources say). I did multiple low light tests and I always got more noise at ISO 3200 than all the ISOs that were less than 3200. Thank you for sharing!
It’s really weird but I’m actually assured by what you said. Otherwise I’d keep assuming only I got a problematic a7cii😂
@RelaxingJourneys4u I tried several times the other day, and I found if I increase the exposure in post processing to make the noise more obvious, I can tell a7cii does have the dual base ISO at 800 and 3200. At ISO 3200 it looks cleaner than 2500. I'll make another video to show this
@@ConstantineSPhotography Oh nice! Many thanks for pinging me! Looking forward to see your findings in your new video!
@@dumspyrospero no problem 😉 I will put the video link here once it’s published
Thanks a lot for this comparison. If we use fast prime lenses (f1.4, f 1.8) A7Cii seems to be a better choice.
I agree. zve1 ISO 12800 is very impressive, but I rarely need that kind of extreme low light capacity.
@@ConstantineSPhotography Couldn't you just always use 12,800 in low light and just put on ND filters if needed? If so, then the ZVe1 would be the better camera? Lastly, what I am more curious is the dynamic range, highlight rolloff, and color of the two cameras that will make my decision!
@@jaymills1720 Let's say I only need ISO 8000, it makes sense to use ZVE1 12800 + nd filter, but now the problem is, maybe a7cii iso 8000 looks cleaner than that? Will need another test to find out.
As for dynamic range, I don't really see much difference, some online tests claim zve1 has better dynamic range, but I think they're both great.
@@ConstantineSPhotography thanks. If you could only choose 1 for video which would it be
Thank you for the good test as always! As a ZVE1 user who seldom use SLog3 with 2nd base ISO, I wish the results is opposite, sigh! Do you think you can do one more test: A7CII shoot in 4k60p (cropped) vs ZVE1 4k60p in low light? If take the lens focal length equivalent, even better?:)
Sounds interesting, I'll do a test of 4k 60p in low light, what do you mean take the lens focal length equivalent?
@@ConstantineSPhotography sorry, wrong typed, I meant if take the focal length into consideration:). Say if you use a 24mm on A7CII, in 4k60p is 36mm equivalent? Then it will be great if you use a 35mm on ZVE1? And with the same aperture?? Ha, i request too much:). You already done great!
Don't worry, I'm curious about the result too! I think I'll put this comparison in the complete A7cii vs ZVE1 comparison video, might take a short while😅😅
@@Lost-In-Indonesia the video is out! ua-cam.com/video/A-TtqX-gAec/v-deo.html at around 5'50, hope it's helpful!
@@ConstantineSPhotography Yes, thank you for the good test! :) I watched every video you posted! And I learned a lot from your channel too! 👍
Fantastic video. Thank you!
Thanks for watching! Glad it helps!
Gorgeous @ 0:08 what settings do you use for this this type of walking footage? (ISO, F-Stop, Focus settings). I find that when filming walking footage in low light, the camera has a tendency to pull focus to the people walking by, ruining the video. How did you prevent this?
Thank you. This footage was shot with s-log3, ISO3200, 1/125s, f4, autofocus wide. I think the focus transition speed also matters, I set it to 5/7, and af subject shift sensitivity also to 5. If you still think the focus pulling is obvious, you can set these two to even lower.
@@ConstantineSPhotography Great, thanks!
@@ConstantineSPhotography One more thing, I noticed you said 1/125s. Does that mean this video was 60 fps? Thanks again.
@@WillieFungo no it's 24fps, I set a faster shutter speed because I found that sometimes when you shoot walking videos in low light environment, low shutter speed can lead to jittering movement.
Thank you! I think I'll trade my A7C for A7CII now
I believe you won’t regret it!
A7c i am pretty sure beat the a7cII in low light. Cine1 with custom settings give excellent result. A7cII is better in grip, stabilization and evf, but you can put the a7c on a gimbal and get better result with a7c without any cropping. The grip can be improved with a custom handle. The price is affordable now. The sensor has better low light performance. At the current price a7c is a very good option.
@@CC-gt3ro That's quite surprising. I don't have a chance to compare these two cameras. Have you tested their s-log3 low light performance?
@@ConstantineSPhotography in slog 3 , the a7cII will be better as it is 10 bit 4:2:2 but in sun light only. Cine1 will beat it with less color noise and accurate color. But my point is a7cII has definitely improved some of the specs but a7c is still a very good option for the price today. PP standard is very good. Its 1080p60 and 120 are very high quality and can be upscaled to 4k with Davinci Resolve, without cropping. A7c + weebill 3s beat any camera in stabilization. Cine1 is better than slog2 and slog3 in 8 bit camera, i would not use slog in low light anyway even with 10 bit camera. The 24Mp sensor has one of the best low light performance on any camera. (See dpreviews)
@CC-gt3ro yea...I was thinking the 24mp on the A7C will let in more light because the pixels will be bigger tha than pixels on the A7CII.
That's why the A7S3 is so good in low light. It's only 12mp but those 12mp are bigger on a full frame sensor
Ill tell you more! A7Siii has less noise and more dynamic range at the same setting with the same lenses as the ZVE1 !!!! Wouldnt have believed it, but I did the test myself!
Any update on this..Im thinking about an A7CII but not having a daul based iso like most of sony cameras might not get it🤷♂️
Sadly, I tried several times but still can't see any noise reduction from ISO 2500 to 3200. But nobody seems to be talking about this. Most information on the internet only says it has the same sensor as a74 so assumes they have the same base ISO.
@therealdeal4492
I tried several times the other day, and I found if I increase the exposure in post processing, I can see the obvious noise, this way I can tell a7cii does have the dual base ISO at 800 and 3200. At ISO 3200 it looks cleaner than 2500
Here’s the new test result: ua-cam.com/video/A5f0mgegeBg/v-deo.htmlsi=yIIZHw7o-gI7Jajt
In the case of Zv-E1 vs A7sIII and A7cII vs A7iv, there were test done showing that even when same sensors were used, there are differences in Luminance noise and Color noise characteristics at high ISO
I've always assumed they would have the same results (or at least very similar)
@@ConstantineSPhotography Thats what i would expect as well. At max ISO51200 , A7iv Exhibits more Color Noise, A7Cii more Luminance Noise. You can refer to "tabinotomo"'s test vid "SONYα7CIIで夜景撮影！デュアルベースISO検証" for references. In his a7cii slog3 test, the A7cII does clean up at 2nd base 3200. Regarding your query why the a7cii did not clean up at 2nd base 3200, you might want to check if profile was set for slog3. Not sure if you are aware, different profiles - Different dual base isos. S-Cinetone , Slog3 etc. Stills and Video mode have different base isos as well. Stills 100 and 400.
I'm very sure it's slog3 and I did several tests to double check, still the same. But I'll look into it, thanks for sharing!
Hi which image do you think is better for photos and videos in terms of sharpness and colors?
For photos definitely A7cii, for videos it depends on what ISO number you mostly need. ZVe1 would have better performance at extreme low light.
@@ConstantineSPhotography Ok, I usually film in rooms with normal light? Flexible ISO 100-3200?
Which camera do you think is generally better in terms of colors and sharpness?
@@neveoney7865 If you take more photos than videos or if the need of both photos and videos is equal, go for a7cii. I think color and sharpness depend more on the lens than on the camera, since both zve1 and a7cii are already very good.
Can you tell me the ISO values for the Sony 7C ii for SLOG3, Base ISO and Cinetone?
Base ISO for s-log3 is 800 and 3200 (but according to my tests I doubt the effect of iso3200)
For s-cinetone it's 100 and 2000
last iso 128 000?
yes the lest scene is shot with iso 12800
Yeah it’s weird that the ZVE1 has different results at different ISO 😅
ZVE1 has 2 base ISOs in s-log3 at 640 and 12800, which means at these 2 numbers the footage will look the cleanest.
Its not weird. Its the same sensor at the A7S3 and FX3.... it would be weird if it didn't.
支持你,加油
感謝你！
The ZVE1 outperforms the A7 at 12800 and above so you need to shoot at a base ISO. However, if you are run and gunning in dark environs, and not setting ISO, the A7 would be better for SLOG but not necessarily other profiles. But I can’t be bothered with SLOG and instead use S Cinetone with a lower second base ISO, and so the ZVE1 performs better than the A7C in that scenario at sub 12800 more 'normal' ISO levels.
So the tests isnt really which performs better at low light, theres no question the sensor on the ZVE1 performs better at low light, but which one is better at lower ISOs in SLOG.
I’d be v interested to see the test again using S Cinetone.
I agree, but aren't both cameras have the base iso of 2000 in s-cinetone?
@@ConstantineSPhotography yes 100 and 2000 but between those figures and above 2000 the ZVE1 should have less noise due to its much larger light gathering pixels. I shoot S Cinetone and it’s very clean in extremely dark environs, even though it pushes above 2000.
Really you can’t use the ZVE1 without ND filters in S log as you need it sub 640 in the day or 12800 really at night. It’s a better low light performer than the A7Cii at Slog as it’s cleaner at 12800, but it comes with hassle. If you want to shoot Slog and run and gun and not set ISO, because the camera would pick usually a lower iso even when it’s quite dark, then A7Cii is easier. The 12800 is almost overkill, and it results in noisier image at lower ISO. I’d have preferred it to be 6400 personally. But it will shoot clean in very, very dark environments.
ZVE1 is a low light wonder, it’s just its dual gain is set at extremely high levels in Slog, I am not sure why Sony set it up as they did, whether it was a choice, or there’s a physics reason behind it.
I don’t have the A7Cii so would be very interested to see both cameras pushed way up high in SCinetone to see which is best, and I’d expect that to be ZVE1.
Sounds interesting, I think I can do a test about that. Will put the link here once the video is published!
yeah that's weird a7cii didn't clear up at the second base ISO... we've been lied to by Sony. haha jkjk
At first I thought the setting is wrong, but I checked many times and did several more test, still the same
