New Sony A7r III Announced – Faster & More Powerful, 4K/30p, 1080p/120fps and Hybrid Log Gamma

Well, we kind of got some big news today! After weeks of speculation, rumors, and he said/she said, Sony officially announced the new A7r III earlier today. The new Sony A7R III camera features the same body as the a7r II and the same massive full-frame 42.2 megapixel CMOS sensor, however adds plenty of new features such as dual SD card slots, a new battery (the one from the Sony a9), new processor and faster AF.

And if the new Sony A7r III is to be a measuring stick for what is about to come (mainly the Sony a7s III, which my guess is will be launched before the end of the year or at least by March 2018), you can bet your bottom dollar, that you’ll see the majority of these improvements in future models in the lineup – mainly the a7s III, which many of us are eagerly expecting, given its predecessors’ more “video oriented” approach.

So, what is new in the new Sony A7r III? Well, quite a lot actually. Sony have implemented a new front-end LSI that effectively doubles the readout speed of the image sensor, as well as an updated BIONZ X processing-engine that boosts processing speed by approximately 1.8x compared to the a7R II predecessor. These powerful components allow the camera to shoot at faster speeds while also enabling its impressive ISO range of 100 to 32,000 (expandable to ISO 50 – 102,400 for still images).

Equipped with a refined image processing system, the a7R III can shoot 42.4MP images at up to 10 fps with continuous, accurate AF/AE tracking for up to 76 JPEG / RAW images or 28 uncompressed RAW images; 10 fps mode is available with either a mechanical shutter or a completely silent shooting, adding to the immense flexibility of the camera.

The camera can also shoot continuously at up to 8 fps in live view mode with minimal lag in the viewfinder or LCD screen. There is no optical low-pass filter for maximum resolution – something that photographers would love.

The a7r III also gets 399 focal-plane phase-detection AF points that cover approximately 68% of the image area in both the horizontal and vertical directions. There is also 425 contrast AF points, an increase of 400 points compared to the a7R II. This advanced system delivers AF acquisition in about half the time as the a7R II in low-light conditions, with tracking that is approximately 2x more accurate as well.

The big new features in the video department are the addition of HLG (Hybrid Log Gamma), S-log3 gamma, and a new 120fps super slow-motion option in 1080p. The new a7r III shoots in UHD 4K (3840×2160 pixels) at a maximum of 30p across the full width of the full-frame image sensor. In Super 35mm mode, the a7r III uses a full pixel readout without pixel binning oversampling a roughly 5K image it to produce high quality 4K footage with exceptional detail and depth.

The video codec is the same 8bit XAVC-S, and the HDMI output is limited to 8bit 422, so don’t expect a GH5-like earth-shattering 10bit specs, however with its new powerful processing and excellent sensor, the A7r III should be able to produce incredible 4K video.
