Welcome to a new world of imaging with resolution, sensitivity, dynamic range, processing speed, and shooting response further enhanced. The α7R III packs pro-style operability into a strong, compact body to give you greater flexibility to take brilliant shots in any situation. With such high power, precision, and potential at your command, you can capture once-in-a-lifetime experiences.
The Exmor R® sensor’s back-illuminated, gapless on-chip lens design increases light sensitivity and provides wide dynamic range, despite its high resolution of 42.4 MP.
A new front-end LSI and BIONZ X™ boost processing speed and are teamed with the Exmor R® sensor to deliver up to 15-stop dynamic range at low ISO sensitivity for stills, enabling richer tonal expression.
The standard ISO range has been extended to ISO 100-32000 (expandable5 to ISO 50-102400), and noise has been reduced by as much as a full stop6 in the mid sensitivity range.
14-bit RAW format output contains rich tonal information from highlights to shadows, and is available even when shooting in silent or continuous mode.

 16-bit image processing
High-resolution Quad-VGA OLED Tru-Finder provides natural, high-precision viewfinder image. The functional advantages of an EVF, such as high visibility in darkness and AF capability when using magnified display, is further enhanced for powerful shooting support. For even greater versatility, the α7R III’s small, light body is robust and rigid enough for rugged use.
This camera allows silent shooting at up to 10fps12 with AF/AE tracking. Silence is critical for shooting wildlife, when even slight noise can mean missing a chance at an ideal shot.
AF performance is improved by inheriting the AF performance used in the α9 and applying it optimally, so once the α7R III captures a wild animal that moves unpredictably, it won’t easily let it go.
Comprehensive Fast Hybrid AF coverage 399 phase-detection AF points covering approx. 68% of image area width and height plus 425 densely positioned contrast-detection AF points13 improve focus that might otherwise be unachievable.
Thanks to much more responsive, enhanced Fast Hybrid AF, AF speed is up to approximately two times faster14 under dim lighting conditions.
The AF algorithm inherited from the α9 accounts for two times more precise6 AF tracking for continuous shooting, even of complex or sudden movement.
Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-315, for more reliable autofocus in dark scenes.
Thanks to enhanced 5-axis in-camera image stabilizer, whenever you want to move and shoot freely, you can rely on the α7R III’s high-resolution performance and mobility, in order to concentrate on the subject without worrying about various types of camera-shake blur.
Pitch and yaw compensation
Horizontal/vertical shift compensation
New stabilization unit/gyro sensors/algorithms effectively raise 5.5 stops20. Five types of camera shake—angular shake (pitch/yaw), X/Y shift, and rotational shake (roll)—are compensated.
The α7R III includes USB 3.1 Gen 1 compatible USB Type-C™ port and sync terminals that enable the camera to be connected directly to external devices without delay. These connections make workflow more seamless and stress-free, even for studio shooting that makes use of PC tethered shooting or flash.
A new suite of imaging apps provides top-quality RAW development, convenient PC tethering, and efficient viewing/management.
Capture One Express (for Sony)23 is free software for high-quality finishing of RAW data. Capture One Pro (for Sony) can be bought for such compatible functions as local adjustment and PC tethered shooting.
This new Pixel Shift Multi Shooting24 reproduces still images that contain true-to-life detail, texture, colour, and overall atmosphere.
In addition to capability to record stunning high-resolution 4K movies2 through 5K (15 MP) oversampling, the camera features a new HLG (Hybrid Log-Gamma)3 picture profile, supporting instant HDR workflow, that offers wide dynamic range for highly precise and lifelike movie images without colour grading.
The α7R III features S-Log for flexible expression of images in post-production and HLG3 for instantaneous HDR workflow—a combination that fulfills various HDR production requirements.
A new HLG picture profile supports instantaneous HDR workflow. Movies recorded in HLG picture mode will appear true-to-life with suppressed blocked shadows or blown highlights, without colour grading.
