Sony α7R III Full-frame Camera
SONY Alpha a7R III Body
Sony says the a7R III is based around the same 42MP back side illuminated 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 shooting rate or reduced rolling shutter in video and electronic shutter
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 42.4MP (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.
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.
42.4MP 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.

3.69-million-dot Quad-VGA OLED Tru-Finder
This high-resolution twice-as-bright electronic viewfinder reproduces fine detail. “Hi” quality mode provides extra-fine views of natural realism on brilliant display.
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.
Conventional autofocus (AF) deals with space alone. 4D FOCUS goes one step further with an innovative image sensor that picks up both space and time to capture moving subjects with new clarity, allowing you to take crisper photos than ever. Plain-old AF is a thing of the past. The future of photography is in motion.
WIDE – Area (2D)
Capture your subject anywhere in the frame. 4D FOCUS activates AF points across a wide area, so the camera can detect subjects throughout the entire frame, instead of just the center.
FAST – Depth (3D)
4D FOCUS instantly detects the distance to your subject and focuses quickly and accurately with advanced AF algorithm, so you never miss decisive moments.
STEADFAST – Time (4D)
Never lose sight of your subject. Our AF algorithm stays focused on the action, and even predicts your subject’s next move, without getting distracted by any obstacles in the frame.
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 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 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.
My Menu: faster to your favorites
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.
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.
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.
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.
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.
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 color grading.
