The new Sony A7R III, announced recently, takes the high-resolution 42.4MP Exmor R CMOS image sensor and gives it a speed boost. A new front-end LSI effectively doubles the readout speed of the image sensor, while an updated Bionz X processing engine promises speeds 1.8 times as fast as the A7R II.
Given that it’s also capable of shooting at 10fps with AF tracking, carries an ISO range of 100-32,000 (expandable to 50-102,400) and offers a 15-stop dynamic range at low sensitivity settings, the A7R III should be useful in all situations and in all shooting conditions. If you’re in live view mode, the camera can still manage an impressive 8fps.
The focusing system has been overhauled from the A7R II, with 399 focal-plane phase-detection AF points covering approximately 68% of the image area, complemented by 400 contrast AF points. This advanced system is expected to deliver AF acquisition that’s twice as fast as it was on the A7R II in low-light conditions, and with tracking that’s twice as accurate.
Video hasn’t been neglected – the A7R III shoots 4K (3840×2160 pixels) video recording across the full width of the image sensor, and uses full pixel readout without pixel binning in Super 35mm format to produce oversampled 4K footage. There’s a new Hybrid Log-Gamma supporting instant HDR footage, and S-Log2 and S-Log3 have been added. The camera also records super-slow-motion at 120fps.
