By far the most popular announcement of Photo Plus Expo 2017 in New York City last week was the Sony A7R III. For the first time, the Sony skipped the unqualified A7 III to start the latest generation of their full-frame mirrorless cameras.

Sony Alpha A7R III

The Sony A7R III closely follows the highly-acclaimed A7R II with a nearly identical body and a new imaging pipeline. One can only actually see this is a generation III model by looking at the back of the camera since the front simply says A7R which means it is high-resolution model of the 7-series. Inside an all-new 42 megapixels BSI CMOS sensor with built-in 399-Point Phase-Detect system claims to deliver an unprecedented 15 stops of dynamic-range.

The new sensor offers faster read-out of 10 FPS and 4K Ultra-HD video down-scaled from full-width sensor output. A deep buffer allows the A7R III to shoot up to 76 RAW files or JPEG images at full-resolution. The sensor is mounted on an improved 5-axis image-stabilization system which is effective to a best-in-class 5.5 stops. It is also sufficiently precise to move the sensor in single pixel increments, allowing the A7R III to capture super-resolution images with full-color information at each pixel by stacking 4 frames just like the Pentax K-1 does.

Its 399-Point AF system features extremely precise and fast Eye-Tracking as well as traditional subject tracking which it can do even when shooting continuously at 10 FPS. Inside the A7R III, a hybrid shutter makes it possible to shoot completely silently. Continuous AF is also available while recording 4K Ultra-HD video at 30 FPS and full 1080p HD video at an incredible 120 FPS.

The body of the Sony Alpha A7R III offers a huge 3.6 Megapixels 0.5″ EVF with a class-leading 0.78X magnification, 100& coverage, an Eye-Start Sensor and true Live-View capability. As a professional-grade full-frame camera, this one includes triple control-dials, a traditional mode-dial and plenty of customizable controls in a weatherproof body.

The Sony A7R III is expected to ship on November 30 for $3200 USD. Amazon, Adorama and B&H Photo are already accepting pre-orders at these links.
