Here are the Sony Alpha A7SIII hands-on review round-up. With a full-frame 12mp sensor, the A7SIII offers exceptional low-light performance.

Sony a7SIII Reviews Round-Up
From ePhotozine Verdict:
For videographers who want high-quality 4K video, the A7S III has got to be extremely desirable. Especially as 4K video is far easier to deal with compared to 8K footage, and can be recorded to SD cards. For stills photographers, then you’ve got to be shooting in really dark conditions for the A7S III to be needed.
Sony A7SIII Pros
- 9.4million dot EVF
- Excellent video quality
- 4K 120fps video recording
- FullHD 240fps video recording
- Improved battery life
- Improved menu system
- Improved touch-screen operation
Sony A7SIII Cons
- 12mp resolution will not be enough for many stills photographers
- Lacks in-camera raw processing
- Doesn’t record CINE-4K
These findings were backed up by Hugh Brownstone, who had similar overheating issues with his unit. Something to keep an eye on…
Ted Forbes at The Art of Photography produced a 19-minute hands-on preview of the camera complete with a deep-dive on the menus.
Camera Labs takes a comprehensive look at photo quality, the new autofocus system, the two different IBIS modes built into the camera, and (of course) 4K/120p video quality.
FroKnowsPhoto put together a really solid 30-minute overview that was filmed on Canon EOS R5, the Sony a7S III, and the Nikon Z6.
In addition to covering a lot of features and details, the video alternates between cameras so you can see the difference in video quality for yourself. As a bonus, he compared the Canon EOS R5’s new Eye AF to the Sony’s version.
