![]() ![]() 4k recording is still available in full-frame or Super-35 modes (the latter still delivering better quality thanks to its oversampling of 5k data), but there’s now the option of S-Log 3 and Hybrid Log Gamma HDR, as well as 1080 at 120p. The Mark III can also shoot bursts at up to 10fps (or 8fps with live feedback) using the mechanical or silent electronic shutter, both with full AF and AE. The sensor offers the same 399-point embedded phase-detect AF system, but complements it with a new 425 area contrast-based system (up from 25 on the A7r II), with Sony claiming AF speed, subject tracking and eye AF all operating twice as fast as before, and at light levels down to -3EV. The built-in stabilisation has also improved to offer 5.5 stops of compensation and support a new Pixel Shift Multi Shooting mode which captures four frames (shifted up, down, left and right by one pixel each) that can be later composited in software to eliminate de-mosaic / false colour artefacts. Starting with image quality, the A7r III may share the same sensor as the Mark II, but couples it with improved circuit design and image processing to deliver a higher dynamic range: Sony claims 15 stops to the 14 on the A7r II, and 14-bit RAW is now available in both the mechanical and electronic shutter modes, including bursts of uncompressed RAWs. The new Mark III shares the same 42.4 Megapixel Back-Illuminated CMOS sensor as its predecessor as well as the same body shape, but inside there’s a number of important differences, not to mention a few on the outside too. Announced in October 2017, it’s the successor to the A7r Mark II launched just over two years earlier. Sony’s Alpha A7r Mark III is a full-frame mirrorless camera with 42.4 Megapixels, 4k HDR video and 10fps continuous shooting with autofocus.

But on the whole, shooting with the A7r Mark III is an overwhelmingly positive and impressive experience that will satisfy a broad array of photographers. ![]() The removal of downloadable apps means Sony needs to find a way to implement interval and bulb timers, the touchscreen is underused, it would have been nice to have 4k at 60p, and only one of the SD slots will exploit the speed of UHS-II cards. The Wifi control also works well, complemented by Bluetooth for seamless location tagging. Earlier concerns over battery life have been banished, and the camera sports improved controls, a more detailed viewfinder, twin card slots and even a touchscreen. ![]() Movie shooters will enjoy good quality 4k along with 1080 / 120p for slow motion. The ability to shoot at 10fps with confident autofocus makes the A7r Mark III surprisingly good at sports, and great for events or wildlife shooting too with its silent shutter. The 42 Megapixel full-frame sensor may be inherited from the Mark II but Sony's improved the processing to deliver superb quality. Summary Sony's Alpha A7r Mark III is a highly capable camera that's equally at home shooting high resolution stills as it is handling fast action or filming quality video. ![]()
