Despite playing second fiddle to the mighty A7R IV, the A7R III continues to deliver sensational image quality and a performance that’ll exceed most photographer’s expectations. The combination of 42.4MP back-illuminated sensor, hybrid autofocus system, 10fps burst shooting, 5-axis in-body image stabilisation and 4K/30p video using the full width of the sensor was always going to be a recipe for success. It’s the way it’s packaged into such a conveniently sized body that gives it the upper hand over bulky DSLRs. Users will immediately become besotted by the quality of the A7R III’s images and the way it provides perfectly useable images at ISO 12,800.

42.4MP 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 42.4MP.
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 (expandable to ISO 50-102400), and noise has been reduced by as much as a full stop 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 a7R III’s small, light body is robust and rigid enough for rugged use.
3.69-million-dot Quad-VGA OLED Tru-Finder

Tough magnesium alloy chassis
Light, high rigidity magnesium alloy top cover, front cover, internal frame and rear cover help make the body very durable
Low vibration shutter
Front and rear curtain shutter vibration are so subdued that the shutter has been tested to withstand over 500,000 shutter cycles.
Resistance to dust / moisture
All major buttons and dials are sealed to minimise entry of dust and moisture ensuring reliable function in tough shooting conditions.
Seize moments with quick precision
Up to 10fps continuous shooting
Capture an instant action with continuous shooting of up to 10fps with AF/AE tracking. Huge data of 42.4MP 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 a7R 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. 2x
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 a7R III also ensures that you can shoot with far less interruption, because you won’t need to change media and battery as frequently.
Focus control via touchscreen
The A7R III has Touch Focus function, and a Touch Pad function for you to fingertip-drag the focus frame intuitively whilst using the viewfinder.
120/100fps viewfinder display
Setting the viewfinder's frame rate to 120/100fps for smooth display makes it easier to track a dynamic subject.
1.44-million-dot tilting LCD screen
3.0 type 1.44-million-dot high resolution LCD screen tilts upwards and downwards for flexible framing and monitoring of the shot.
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
With two media slots, including one that’s UHS-II-compatible for fast data writing, the a7R III can simultaneously or relay record, separate RAW/JPEG data and stills/movies, and copy data between cards.
Extend shooting to professional length
The a7R 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.
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 customise an optimal menu for your own convenience.
New portraiture potential
Eye AF with doubled performance
With the a7R III, Eye AF evolves with two times more immediate, effective eye detection and tracking, even when shooting a moving portrait subject, if the subject is looking down, the face is partially hidden or in poor quality light.
Enhanced image stabilisation: freer shooting
Thanks to enhanced 5-axis in-camera image stabiliser, whenever you want to move and shoot freely, you can rely on the a7R III’s high-resolution performance and mobility, in order to concentrate on the subject without worrying about various types of camera-shake blur.
New stabilisation 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.
Smooth studio workflow
High connectivity for professional workflow
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.
USB 3.1 Gen 1 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.
Different dimension of resolution
Pixel Shift Multi Shooting
This new Pixel Shift Multi Shooting reproduces still images that contain true-to-life detail, texture, colour, and overall atmosphere.
More realistic movies
High-resolution 4K HDR
In addition to capability to record stunning high-resolution 4K movies through 5K (15MP) 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 movies with oversampling
You can shoot and internally record 4K movies oversampled from 5K (15MP) equivalent data in Super 35mm format. The results are startlingly beautiful in every detail.
Improved Fast Hybrid AF
Fast Hybrid AF for movies now autofocuses on subjects throughout an area as wide as the one that applies to stills, and the AF system is very smooth and quick at capturing fast-moving subjects.
Supporting various needs in HDR production
The a7R III features S-Log for flexible expression of images in post-production and HLG for instantaneous HDR workflow — a combination that fulfils various HDR production requirements.
HLG (Hybrid Log-Gamma) 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 a7R III 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.
