Sony’s α7R III delivers the ultimate combination of resolution and speed with a 35mm full-frame 42.4 megapixel back-illuminated Exmor R CMOS image sensor, with no optical low pass filter, 10fps continuous shooting, and fast and precise AF performance. A gapless on-chip lens design and AR (anti-reflective) coating on the surface of the sensor’s seal glass dramatically improves light collection efficiency, resulting in high sensitivity with low-noise performance and wide dynamic range (15 stops).

The updated BIONZ X processing-engine boosts processing speed by approximately 1.8 times compared to the α7R II, while the ISO range of 100–32,000 is expandable to ISO 50–102,400 for still images. The camera boasts 399 phase-detection AF points covering 68% of image area and 425 contrast AF points – an increase of 400 points compared to the α7R II. The α7R III features 5-axis optical in-body image stabilisation with a 5 shutter speed advantage. The camera captures video in 4K (3840x2160) and data is stored with dual SD card slots.

The α7R III features an upgraded high-resolution, high-luminance Quad-VGA OLED Tru-Finder with approximately 3,686k dots, and is the same one found in the Sony α9 camera. It utilises a ZEISS T* coating to greatly reduce reflections, and has a fluorine coating on the outer lens that repels dirt. It also has a customisable frame rate, with options of either 60fps or 120fps. The batteries for the α7R III offer approximately 2.2 times the capacity of those used in its predecessor.
