Sony announces a7R III with faster AF, more fps and longer battery life

Sony’s new high-res full frame mirrorless camera is here. The a7R III brings the same 42.4MP backside-illuminated sensor with no aliasing filter as its predecessor, but adds a focus point selection joystick, AF-On button, twin SD card slots. We also get flash sync socket as well as the higher-capacity battery and the higher resolution electronic viewfinder of the flagship Sony α9.

The Sony a7R III gets a faster Bionz X processor, which combined with a redesigned low-vibration shutter allows for 10 frames per second shooting with full autofocus in both mechanical or electronic shutter mode. The a7R III can capture a total of 87 compressed or 28 uncompressed RAW files in a sequence.

The in-body 5-axis stabilization has been updated to receive a 5.5 steop rating, by CIPA standards.

The new battery is the NP-FZ100 unit from the a9, which doubles the longevity of the previous a7R II – it has a CIPA rating of 650 shots with the LCD and 530 shots with EVF.

The new Sony a7R III can still capture 3840 x 2160 UHD 4K video in either full frame or Super 35 mode – which uses essentially an APS-C crop of the sensor.

Like last year’s a7R II there is a difference in quality. Full frame mode produced the noisier footage and had noticeably less sharpness and dynamic range. Super 35 mode will produce the sharper video but Sony promises quality improvement to both modes.
