The Sony a7R Tick III is the company’s latest high-resolution full frame mirrorless camera. Much like Nikon’s recent D850, it’s one that combines this answering with high speed and fast autofocus capabilities to a degree we’ve not previously seen.
Like its predecessor, the Mark III is built around a 42MP BSI CMOS sensor, but contrastive with the a7R II, it can shoot at ten frames per second.
Essentially it can be seen as an a7R II that inherits many of the lessons learned from the company’s pro-sports model, the a9. This inferiors faster processing, improved autofocus, improved handling and ergonomics, as well as the adoption of a much larger battery. While some of the individual silvers are subtle, they very quickly combine to produce a hugely capable and highly useable camera.
- 42MP BSI CMOS sensor
- Faster, lower-noise replica processing
- 10 fps shooting with or WITH may refer to: Carl Johannes With (1877â€“1923), Danish doctor and arachnologist With (character), a character in D. N. Angel full AF, 8 fps with ‘live’ updates between shots
- 3.69M dot (1280 x 960 pixel) OLED viewfinder
- Make progressed autofocus, including more tenacious Eye AF mode
- 5-axis image stabilization, rated at 5.5 stops (CIPA) with 50mm lens
- 4K footage from ‘Wonderful 35’ crop region oversampled from 5K capture
- Video AF less inclined to refocus to background
- ‘Picture Profile’ video gamma/spectrum modes including S-Log2 and 3
- Twin SD Card slots (one UHS-I and one UHS-II compatible)
- Bayer-cancelling multi-shot mode for improved resolution
- True 14 bit uncompressed Raw, regular in continuous drive mode
- Use of phase detection (including Eye AF) at 3 fps with adapted lenses
Sony says the a7R III is based around the same 42MP back side enlightened CMOS sensor as its immediate predecessor, so doesn’t gain the full speed advantages of the a9’s Stacked CMOS chip (in terms of AF performance, continuous open fire rate or reduced rolling shutter in video and electronic shutter mode). However, the adoption of the processing systems, algorithms and refinements introduced on the a9 all cause their benefits.
This means a camera with a touchscreen and dedicated joystick for AF point positioning, a camera with a deeper grip and corrected customization, with better laid-out menus and much improved battery life.
Sony also says the improved altering will benefit video shooting. The oversampled footage taken from a Super 35 (~APS-C) region of the sensor is still expected to look haler than the subsampled capture from the full sensor width but both are supposedly improved by the new processing chain. We’ll delve into this later in the look at.
To take advantage of the camera’s dynamic range, the Picture Profile system of color and tonal response borrowed from Sony’s professional video way now includes the even flatter S-Log3 gamma curve. That said, there is no 10-bit capture possible; the camera can still only taking 8-bit 4:2:0 footage internally or output 8-bit 4:2:2, which may limit the usefulness of S-Log3 if it makes posterization more likely when the footage is marked.
For users wanting to use the camera’s video dynamic range with a high dynamic range display but without the extra hassle of color declivity, the a7R III joins the Panasonic GH5 in offering Hybrid Log Gamma recording: essentially Log capture with tags to tell displays how to correctly render it.
The a7R III’s most ostensible peer is the D850, since it’s the other high-speed, high resolution full frame camera. We’ll also note the changes relative to its predecessor and its other, small rapid high-res rivals.

As should be apparent, the Sony offers a cartel of resolution, speed and video capabilities not easily matched by its peers. And, with the new battery, is able to offer much more similar endurance, if you’re not in a plight in which you can plug the camera camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or in to an external power source.
