Sony Announces a7R Mark III

Sony's latest addition to their full-frame mirrorless line-up, the a7R Mark III, features a full-frame 42.4MP backside illuminated Exmor R CMOS image sensor with Evolved Image Processing and 399 phase-detect autofocus points covering 68% of the image area and 425 contrast autofocus points. 5-axis optical in-body image stabilization now compensates for 5.5 stops..

The a7R III shoots up to 10 frames per second with full AF/AE tracking, which is twice as fast as the a7R II's 5fps, and the buffer captures up to 76 JPEG/RAW and 28 uncompressed RAW. 

ISO range has been expanded to ISO 32000, up from 25600 on the a7R II, and the camera is capable of up to 15 stops of dynamic range. 

The in-body optical image stabilization also enables Sony's new Pixel Shift Multi Shooting mode, which captures 4 separate photos shifted by 1 pixel each which are composited into a single 169.2MP megapixel photo for increased resolution and color accuracy.

On the back is a 3.69 million dot Quad-VGA OLED Tru-Finder EVF with reflection- and dust-resistant coatings and a 60fps or 120fps frame rate. There's also a 1.44 million dot rear tilting LCD.

For more information, see the Sony press release here. The Sony a7R III (body only) will be available in December with an MSRP of $3999.99.
