A7S III is Sony's new, video-centric full-frame mirrorless camera. It can shoot 4K video at 120fps (yes, still at 10-bit) and it is divine. Unlike the older A7S cameras, the Mark III uses the newer, larger Sony NP-FZ100 batteries, which should be good for 500-600 stills.
This rundown provides our analysis on 8 third-party reviews. The sentiment scores, summaries, and key takeaways that we select are based on these reviews and may differ from the original publication.

In addition to RAW and JPG, the A7Siii can also shoot in the newer HEIF format, which you might think of as an HDR still photo. The only thing that's keeping me from running out and selling my organs to buy this $3,500 camera is that I have dreams of one day blowing up my nature photos and seeing them on a gallery wall.

Reviewers from cameralabs have found the following[***]:
Sony’s dumped the half hour limit of some rivals and designed the internals to better dissipate heat without the need for active cooling. Sony claims the A7S III can record an hour of 4k uninterrupted, but I found it could do much better in most modes. In 4k 60p, I managed a single 107 minute clip before I filled my 128GB card, with 25% battery remaining and the camera happy to continue filming.

  • Superb 4k video quality

Sentiment Score[*] 87%
Reviewers from pcmag have found the following[***]:
The Sony a7S III is the only current-generation mirrorless camera with a relatively low pixel count sensor. Its 12MP BSI sensor offers cleaner high- ISO imaging and video than more typical 24MP cameras. The ability to record in 4K at up to 120fps can add slow motion to projects without having to drop back to HD resolution.

Reviewers from techradar have found the following[***]:
The Sony A7S III is a fantastic camera for video and stills. It has an ultra-fast, ultra-expensive memory card format, but it does support it nonetheless. There's support for the new HEIF photo format, H.265 video capture, and clean 16-bit raw output at 4K 60fps. With ISO settings ranging from ISO 2000-4000 it is a liberating camera to use.
