I picked up on this too. It was just badly worded - the S2 can definitely record 1080p in full frame mode. Rather than saying it can only record 1080 in APSC, they meant - in APSC it can only record 1080p - ie, no 4K In APSC.

Thanks

+Salman Anik, the A7S II can record full HD video using the full pixel readout of the sensor.

+Markisen Marco - Unfortunately, Chase Kubasiak from Zacuto doesn’t mention what picture profile they shot the test shots in. As for noise reduction, I don’t know if they used any in post, though one would think for a comparison they would want to touch the files as little as possible in order to display an accurate account of what the video looks like out of the camera. The test with the girl sitting on the porch would be comparing the low light performance of the a7R II when shot in APS-C mode and the a7S II shot full frame both with 1080 video. *Christina* AskPhoto@bhphoto.com

When you switch to movie mode or start recording a movie with [ File Format] set to [XAVC S 4K], [APS-C/Super 35mm] is locked to [Off]. If an APS-C size dedicated lens is attached, the edges of the screen may appear dark. When shooting 4K movies with this camera, we recommend using a lens compatible with the 35 mm full-frame format. bit.ly/2cDQIGB Video Format: 4K XAVC S 3840 x 2160p / 29.97 fps (100 Mbps) 3840 x 2160p / 29.97 fps (60 Mbps) 3840 x 2160p / 23.98 fps (100 Mbps) 3840 x 2160p / 23.98 fps (60 Mbps) 3840 x 2160p / 25 fps (100 Mbps) 3840 x 2160p / 25 fps (60 Mbps) High Definition XAVC S 1920 x 1080p / 120 fps (100 Mbps) 1920 x 1080p / 100 fps (100 Mbps) 1920 x 1080p / 120 fps (60 Mbps) 1920 x 1080p / 100 fps (60 Mbps) 1920 x 1080p / 59.94 fps (50 Mbps) 1920 x 1080p / 29.97 fps (50 Mbps) 1920 x 1080p / 23.98 fps (50 Mbps) 1920 x 1080p / 50 fps (50 Mbps) 1920 x 1080p / 25 fps (50 Mbps) High Definition AVCHD 1920 x 1080p / 59.94 fps (28 Mbps) 1920 x 1080i / 59.94 fps (24 Mbps) 1920 x 1080i / 59.94 fps (17 Mbps) 1920 x 1080p / 23.98 fps (24 Mbps) 1920 x 1080p / 23.98 fps (17 Mbps) 1920 x 1080p / 50 fps (28 Mbps) 1920 x 1080i / 50 fps (24 Mbps) 1920 x 1080i / 50 fps (17 Mbps) 1920 x 1080p / 25 fps (24 Mbps) 1920 x 1080p / 25 fps (17 Mbps) High Definition MP4 1920 x 1080p / 60 fps (28 Mbps) 1920 x 1080p / 29.97 fps (16 Mbps) 1280 x 720p / 29.97 fps (6 Mbps) 1920 x 1080p / 50 fps (28 Mbps) 1920 x 1080p / 25 fps (16 Mbps) 1280 x 720p / 25 fps (6 Mbps) >Mark

Both are great options and it really will be a matter of which way you want to go. You have laid out the heart of the differences between these cameras. The GH5s offers 10-Bit recording, it also offers 4K at up to 60fps and higher bit rates for the files. While the A7SII is a full frame camera that works exceptionally in low light conditions. Which of these features is most important to you will determine the right choice for you. Thanks! -Joey P

Slog 3 is a higher gamma curve and will provide better shadows with a contrast. Slog 3 would be better for cinematic editing and color correction , and would be closer to a cinema camcorder than a DSLR. *Andrea

Doug Guerra, from B&H, breaks down the key similarities and differences between the a7R II and the a7S II. Both cameras share the updated body design, five-axis in-body image stabilization that was first introduced by the a7 II, as well as offering advanced video features such as internal 4K recording and S-Log gamma settings. However, each camera offers its own distinct advantages for photographers and videographers. The a7R II, with its 42MP back side illuminated sensor and 399-point phase-detection autofocus, delivers high-resolution still images, while the a7S II features a 12.2MP sensor that’s optimized for low-light sensitivity and full-frame 4K quality, while also adding additional video-specific features. Which camera is right for you? Watch the video to find out! bit.ly/28MKwbu >Mark

While the Sony Alpha a7S II has a much higher ISO range and can shoot video in much lower light, if you are using the camera for still astrophotography usage needs, the Sony a7R II Mirrorless Digital Camera has better low-light performance with less image noise, and as such, would be my recommendation between these two cameras for astrophotography usage needs. The a7R II also has about 2/3 stop more dynamic range and sees more colors with a wider color depth.

Same Here :D

Only for 1080p at 120fps it is. If you shoot at even 1080p 60 fps its full frame.

With the a7R II, shooting in the APS-C mode (super 35) has several advantages: it allows for full-pixel readout, which can result in sharper video; it has less noise at higher ISO; and one can use more lenses. *Christina* AskKZfaq@bhphoto.com

get the a7s II or the a6500 :D

Agree! ^

All of that was covered towards the end. It's too bad people generally aren't somehow able to watch a whole video before commenting something stupid on it..

+AM679 Hello. There's a part I completely on the photo qualities: kzfaq.info/get/bejne/pJ6gntZ23arDZmg.html​

+AM679 the title reads "Video Comparison" for this particular youtube video.

Yes it does. That's no excuse for not watching the video before asking questions about it.

+Imani kay - Try playing the video at a higher rate. On the bottom right hand of the screen if you click on the "settings" icon, there is an option there to adjust the quality, make sure the speed is set to normal. - Yossi

+B and H it was set to normal and hd, but I think it's just me. Could be KZfaq's compression. It felt as if the video encoding wasn't that good.

+Imani kay The encoding is just fine and it looks great on even the basic monitors I'm using. Mark S

mark=generation=version

+Troll literally it makes sense. But conventionally "mark" is used by Canon as you already know. It is just confusing when people use "mark" for Sony products. It kinda gives an impression that the people who use "mark" for Sony products have used Canon a lot previously and don't want to give up the language for one reason or other.

No, it only gives the impression that this only matters to people very concerned about things that don't matter.
