Sony Releases the a7R III With 42MP, 10fps, 15-stop DR, 5.5-stop IS and 4K Video

Sony has pulled all the stops with the release of the a7R III, an update to the highly successful and highly-acclaimed a7R II. It probably has everything you could ask for—a resolution of 42MP, 15-stop Dynamic Rage (DR) and shoots at up to 10fps with full AE/AF tracking. This is twice as fast as the 5fps offered by the a7R II Additionally, the in-body image stabilisation provides 5.5 stops of stabilisation—the world’s highest for a full-frame camera. The buffer is able to store up to 76 JPEG/RAW photos and 28 uncompressed RAW files, and the updated BIONZ X processing engine is able to process them at 1.8 times faster than the a7R II. This means that you can still use many of the camera’s key features while a batch of photos are still being written to the memory card.

The a7R II features a ISO range of 100-32,000, expandable to 50-10,2400, and at the low ISOs, the camera is able to achieve an extremely high dynamic range of 15-stops. There’s also a Pixel Shift Multi Shooting mode, similar to what Olympus have on their OM-D E-M5 II, which captures 4 separate photos shifted by 1 pixel to produce a 169.2MP image.

The AF system has been substantially improved, with 399 phase-detection AF points spanning 68% of the image area, in addition to 425 contrast-detect AF points. With this improvement, the a7R III can lock focus twice as fast as the a7R II in low light. Eye AF is also twice as accurate as the a7R II.

At the back of the a7R III is a 3.686M dot OLE EVF with coatings that reduce reflections, and dirt resistance. The refresh rate can be toggled between 60 and 120fps. Below the EVF is a 1.44M dot tilting LCD screen.

On the video side of things, the a7R III can record 4K video using the full width of the sensor, and also shoot in super 35mm without pixel binning. There’s Hybrid Log-Gamma (HLG), S-Log2, S-Log3 and full HD recording at 120fps at up to 100Mbps.

The Sony a7R III will be available from November at US$3,200.
