Sony A7SIII features a 12MP full-frame sensor just like its predecessor but there’s a good reason for it. This allows for best-in-class low-light performance (maximum sensitivity ISO 409.60) while still delivering high-quality 4K video files. Speaking of 4K, you can now record at up to 60 fps with no crop or at 120 fps with a small crop (1.1x). Full HD (1080p) video recording is also available at up to 240 fps and, according to Sony, the A7SIII will not suffer from overheating.

There are also new codecs to choose from including the XAVC-S-I with a bitrate of up to 600 Mbit/s (75 MB/s) and less data hungry XAVC-HS ( up to 200 Mbit/s or 25 MB/s). The brand new Sony camera can record in 10-bit 4:2:2 internally, but it also comes with a full HDMI 2.1 port that’s capable of outputting 16-bit 4K at up to 60 fps. Quite impressive!

Many of the new features are available thanks to the brand new BIONZ XR processor, which has eight times as much computing power as the previous model. Autofocus also received a huge upgrade compared to the A7SII. The camera now has 759 phase detection points and 425 contrast detection points that cover 92% of the image sensor. Of course, it also packs all new AF algorithms including human and animal Eye AF and real-time tracking.

The Sony A7SIII is a bit thicker than its predecessor but that’s understandable considering the number of new features we’re getting. Videographers will be happy to hear that the camera finally comes with a fully articulating screen, which was a hugely requested feature in the past. The A7SIII also sports a class-leading OLED viewfinder with 9.44 million dots!

Finally, let’s discuss memory cards. Sony A7SIII features two card slots that are slightly wider than your average SD card slots. The reason is that the camera can use both CFexpress Type A cards and UHS-II SD cards. Sony will launch their first CFexpress Type A cards along with the camera.

Sony A7SIII will retail for approximately $3,500 and should start shipping in September.
