Spectacular 42.4MP full-frame resolution

The 42.4MP high-resolution, back-illuminated Exmor R® CMOS sensor utilizes a gapless on-chip lens design and AR (anti-reflective) coating on the surface of the sensor’s seal glass to dramatically improve light collection efficiency. This results in high sensitivity with low-noise performance and wide 15-stop4 dynamic range. No optical low pass filter maximizes resolution, while also having the ability to output 14 bit RAW15 format even when shooting in silent or continuous mode. Nothing less than spectacular images.

An evolutionary leap in image processing power

The a7R III features 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 1.8 times compared to the a7R II. These powerful components work together to allow the camera to shoot at faster speeds while also enabling its impressive ISO range of 100 - 32000 (expandable to ISO 50 – 102400 for still images) and massive 15-stop dynamic range at low sensitivity settings. This ensures outstanding overall performance at all settings and in all shooting conditions.

Up to 10fps1 with Silent or Mechanical Shutter

The a7R III is equipped with a refined image processing system that allows it to capture full 42.4MP images at up to 10 fps with continuous and accurate AF/AE (autofocus and auto exposure) tracking for up to 76 JPEG / RAW images or 28 uncompressed RAW images. This high speed 10 fps mode is available with either a mechanical shutter or an electronic shutter for completely silent shooting, adding to the immense flexibility of the camera. The a7R III can also shoot continuously at up to 8 fps in live view mode with minimal lag in the viewfinder or LCD screen. These high-speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail.

More realistic movies

Movies of extraordinary presence result from innovation supporting 4K HDR images of high resolution, broad dynamic range, and wide colour gamut.


Shoot up to 76 images continuously

Shoot up to 76 images continuously

Capture up to 76 compressed RAW or JPEG images in a continuous burst. This allows you to confidently concentrate on burst shooting without distraction.

Dual media slots, UHS-II support

Dual media slots, UHS-II support

With two media slots, including one that’s UHS-II-compatible for fast data writing, the α7R III can simultaneously or relay record, separate RAW/JPEG data and stills/movies, and copy data between cards.

Extend shooting to professional length
