Product description
Announced Oct 25, 2017

The Sony a7R Mark III is a full-frame mirrorless camera that uses a 42.4MP stabilized BSI CMOS sensor. The Mark III has numerous improvements over its predecessor, many of which are borrowed from the flagship a9. Faster processing and a redesigned shutter allow for 10 fps bursts (or 8 fps with no viewfinder blackout), and a refined autofocus system promises better subject tracking performance. The design hasn't changed much, with the main additions being a higher resolution EVF, joystick for adjusting the focus point, dual SD card slots and a higher capacity battery. Video can be captured at UHD 4K (30p) using the full-width of the sensor or a Super 35 crop, and 1080/120p option is also available. The a7R III supports S-Log3 and Hybrid Log Gamma profiles, among others.

Our review

It's fair to say that the Sony a7R III is a great option for an incredibly wide variety of photographers. Offering great image quality, fast burst shooting speeds, high quality 4K video and a reasonably compact package, it's an incredibly well-rounded offering. The endless customization options can be daunting at first, but in the end, it's a camera equally at home capturing fast action one moment, and expansive landscapes the next.

Good for: Hybrid stills and video shooters, photographers looking for a versatile tool for a wide range of subjects in a compact package.

Not so good for: Those that need the absolute best in autofocus tracking, those that require even faster burst speeds.
