Reality realized. New worlds.
Refine your sense of reality with α7R III—an ideal partner offering superior speed, high-resolution imaging, pro-class operability, and reliable performance even under harsh conditions.

Animal-eye AF feature now available with software update
A software upgrade is now available to support Sony's new Real-Time Eye AF for Animals. The feature works by automatically detecting and tracking the eyes of animals that you're photographing, for beautiful pet portraits and wildlife shots.

Inspiring maximum creativity
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. 

A portal to unseen worlds
Together, an effective 42.4 MP (approx.) image sensor and enhanced image processor can take imaging as far as adventurous imaginations allow.

Seize moments with quick precision
Doubled AF tracking effectiveness, even during continuous shooting at up to 10fps, advances the evolution of steady, lightning-fast camera performance.

New portraiture potential
Greatly enhanced Eye AF focuses on and tracks an eye with great precision and speed, even when a subject is moving, is looking down and away, or is backlit.

Smooth studio workflow
SuperSpeed USB 5 Gbps (USB 3.2) enabled by a USB Type-C® connector allows high-speed PC Remote data transfer for smooth handling of large RAW data files.

Different dimension of resolution
Pixel Shift Multi Shooting delivers overwhelming resolution, colour fidelity, and texture reproduction, capturing the atmosphere of subject and environment.

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

Depicting scenes in intimate detail
The image processing system has evolved to deliver high resolution and low noise throughout a wider ISO range. The camera depicts the mood of every scene’s surroundings as well as texture of details.

42.4 MP3 full-frame Exmor R™ CMOS sensor
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.

Greatly enhanced image processing
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.

Wide standard ISO 100-32000 range
The standard ISO range has been extended to ISO 100–32000 (expandable4 to ISO 50–102400), and noise has been reduced by as much as a full stop5 in the mid-sensitivity range.

14-bit RAW output for rich gradations
14-bit RAW format output contains rich tonal information from highlights to shadows, and is available even when shooting in silent or continuous mode.

Strong, light, reliable design takes you further
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.

Seize moments with quick precision

Up to 10fpscontinuous shooting

Capture an instant action with continuous shooting of up to 10fps with AF/AE tracking. Huge data of 42.4 MP imaging maintains high image quality that is advantageous for your creative trimming.

Shoot continuously in absolute silence
This camera allows silent shooting at up to 10fps with AF/AE tracking. Silence is critical for shooting wildlife, when even slight noise can mean missing a chance at an ideal shot.

Dramatically evolved AF performance
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 points improve focus that might otherwise be unachievable.

Up to 2x faster (approx.) AF response
Thanks to much more responsive, enhanced Fast Hybrid AF, AF speed is up to approximately two times faster under dim lighting conditions.

AF tracking improved by approx. 2x5
The AF algorithm inherited from the α9 accounts for two times more precise AF tracking for continuous shooting, even of complex or sudden movement.

Reliable AF down to EV-3 brightness
Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-3, for more reliable autofocus in dark scenes.

Never waste a moment
New multi-selector, AF-ON button, and touch focus functions make focus operation quick and intuitive. With built-in dual slots and compatibility with large-capacity rechargeable-battery NP-FZ100, the α7R III also ensures that you can shoot with far less interruption, because you won’t need to change media and battery as frequently.

Shoot up to 76 images continuously
Capture up to 76 compressed RAW16 or JPEG images in a continuous burst.17 This allows you to confidently concentrate on burst shooting without distraction.

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
The α7R III can use a NP-FZ100 battery with approx. 2.2 times as much capacity as a NP-FW50 battery. USB Type-C® and Multi/Micro USB ports allow connection of external batteries for extended shooting.

Rating function
With rating function, you can rate recorded still images from 1 to 5 stars anywhere right on the spot, using the playback screen to perform the function if it is assigned to a custom button.

Grouping display for continuous shots
A series of photos shot in continuous mode can be reviewed as groups, play index display is improved, and continuous groups can be deleted or protected at once.

My Menu: faster to your favourites
Register up to 30 frequently used items on the new My Menu for instant recall. You can create and customize an optimal menu for your own convenience.

Eye AF with doubled performance
With the α7R III, Eye AF evolves with two times5 more immediate, effective eye detection and tracking, even when shooting a moving portrait subject.

Enhanced image stabilization: freer shooting
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.

5-axis optical in-body image stabilization
New stabilization unit/gyro sensors/algorithms effectively raise 5.5 stops. Five types of camera shake—angular shake (pitch/yaw), X/Y shift, and rotational shake (roll)—are compensated.

High connectivity for professional workflow
The α7R III includes SuperSpeed USB 5 Gbps (USB 3.2) 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.

SuperSpeed USB 5 Gbps (USB 3.2) for fast data transfer
This makes PC tethered shooting available for smooth handling of big RAW image files, so you can quickly review images on a PC and continue shooting without much delay for file transfers.

Sync terminal available
A standard sync terminal is provided for convenient synchronisation with studio flash units and other external lighting equipment.

Imaging Edge™ Remote, Viewer and Edit
Elevate your photography with Imaging Edge desktop applications. Use "Remote" to control and monitor shooting live on your PC screen; "Viewer" to quickly preview, rate, and select photos from large image libraries; and "Edit" to develop RAW data into high-quality photos for delivery. Get the best from Sony RAW files, and manage your productions more efficiently

Imaging Edge™ Webcam
The Imaging Edge Webcam application makes it easy to use your Sony camera as a high-quality webcam, with wide compatibility, for impressive live streaming and conferencing.

Pixel Shift Multi Shooting
This new Pixel Shift Multi Shooting21 reproduces still images that contain true-to-life detail, texture, colour, and overall atmosphere.

High-resolution 4K HDR
In addition to capability to record stunning high-resolution 4K movies through 5K (15 MP) oversampling, the camera features a new HLG (Hybrid Log-Gamma) picture profile, supporting instant HDR workflow, that offers wide dynamic range for highly precise and lifelike movie images without colour grading.

Shoot and record 4K movies1 with oversamplin
You can shoot and internally record 4K movies oversampled from 5K (15MP) equivalent data in Super 35 mm format. The results are startlingly beautiful in every detail.

Supporting various needs in HDR production
The α7R III features S-Log for flexible expression of images in post-production and HLG for instantaneous HDR workflow—a combination that fulfills various HDR production requirements.

HLG (Hybrid Log-Gamma)2 for instant HDR workflow
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.

S-Log3 for wide 14-stop dynamic range
In addition to S-Log2, the M41 B41 offers S-Log3 for better gradation from shadows to mid-tones and a wide dynamic range of up to 14 stops. New S-Gamut3/S-Gamut3. Cine wide colour space is also supported.
