The tough, durable and compact Sony a7R III features a 42.4MP full-frame back-illuminated CMOS Sensor along with a faster Bionz X processor and front-end LSI processor to deliver high resolution and low noise throughout a wider ISO range. The a7R III is capable of 10 fps silent shooting with full autofocus and 8fps in Live View. The a7R MKIII inherits the 3.69M-dot OLED viewfinder from the Sony a9 along with the the higher-capacity battery of the a9. 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.
Back-illuminated 42.4MP full-frame sensor
The 35mm full-frame Exmor R CMOS image sensor features 42.4-megapixel resolution, back illumination and gapless on-chip lens design for extraordinary sensitivity and dynamic range, anti-reflection (AR) coating on sensor seal glass, and other innovations that unleash the sensor’s power to make images look realistic.
Image processing engine
The latest front-end LSI makes data readout from the image sensor approximately two times faster and the BIONZ X image processor is now about 1.8 times faster. Enhanced image processing realizes lower noise and further extended dynamic range across a wide sensitivity range of up to ISO 32000 (standard ISO, expandable to ISO 50-102400 for stills). Moreover, upgraded Detail Reproduction and Area-specific Noise Reduction achieves noise reduction — equivalent of approx. one stop — in mid-range ISO settings. Also, reproduction of skin colour has been dramatically improved, which is advantageous for portrait shooting. The α7R III also supports 14-bit RAW output even during silent shooting/continuous shooting.
Highly durable and operable in tough conditions
The a7R III body is fortified by lightweight, high-rigidity magnesium alloy top cover, front cover, internal frame, and rear cover. The number of lens mount screws has been increased to six for enhanced durability. Major buttons and dials are sealed. Sealing is provided throughout the body to minimise entry of dust and moisture.
An evolved image processing system and α9 camera AF algorithms optimised for the α7R III improve AF speed, precision, and tracking performance. 399 phase-detection AF points and 425 contrast-detection AF points provide high-density wide-area coverage. Up to approximately two times faster AF speed and two times more precise AF tracking performance let you capture and maintain focus on nimble wildlife in unpredictable motion. The α7R III also autofocuses reliably down to EV-3 brightness.
Eye AF with doubled tracking performance
Eye AF’s enhanced precision, plus two times greater AF speed and AF tracking performance14 further assist you to easily shoot a portrait of a moving subject using AF-C even during continuous shooting, and even if the subject looks down and away from the camera, or is backlit with face in partial darkness. The α7R III’s E-mount body supports Eye AF for A-mount lenses mounted via an adaptor.
Up to 10fps with AF/AE tracking
With new shutter unit and image processing system refinements, the α7R III can shoot continuously at up to 10fps with AF/AE tracking (up to 8fps with minimal display lag in live-view continuous shooting mode) for easy, stable shooting of even intensely active subjects. An electronic shutter allows silent, vibration-free shooting of wildlife when even slight noise can mean missing an ideal shot.
Up to 76 images in continuous shooting
Greater buffer memory, system speed, and UHS-II support allow the α7R III to capture up to approx. 28 uncompressed RAW, or 76 compressed RAW or JPEG images in a continuous burst at 10fps. Fn menu/menu display access, setting changes and review playback can occur during data writing. A countdown of the number of still images remaining to be written to memory is on display during playback.
In-body 5-axis image stabilisation with up to 5.5-stop shutter speed advantage
Now more effective than ever for the α series, this comprehensive system compensates for five types of camera shake that tend to blur images: pitch/yaw shake when shooting at longer focal lengths; X/Y shake in close-up (including macro) shooting; and roll shake when recording stills at night and movies. It effectively achieves 5.5-stop-faster shutter speed, so the α7R III can take full advantage of its 42.4-megapixel and live-view image performance. Furthermore, it functions with A-mount lenses attached via mount adaptor, as well as E-mount lenses.
Pixel Shift Multi Shooting
Applying mechanisms and control technology of image stabilisation, this new feature composites four separate pixel-shifted images that contain total data equal to approx. 169.6 million, or 42.4 million x 4 (RGGB), pixels to reproduce a single optimal still image of super-high resolution, detailed texture, balanced colour, and realistic atmosphere, with minimal moiré and colour artefacts. Images shot using this feature can be processed with the new Sony imaging software suite. The image sensor is moved in 1-pixel increments while shooting four sequential frames. Each pixel represents R, G, and B information.
3.69-million-dot, high-luminance Quad-VGA OLED Tru-Finder
This approximately 3.69-million-dot Quad-VGA OLED Tru-Finder provides accurate detail, contrast, and black reproduction, while maintaining natural image brightness. High-quality mode, suitable for fine focus adjustment, takes full advantage of rich image data from the image sensor to display more natural high-precision images with minimal moiré and jagginess, so you can concentrate more on shooting. Furthermore, you can choose 120/100fps from the selection of frame rates for the viewfinder to make motion look particularly smooth. Only an EVF such as this one could offer features such as a powerfully enhanced focus magnifier that allows autofocus while a chosen focus area is magnified in the viewfinder.
Touch screen LCD for intuitive focus operations
A 3.0-type LCD touch screen with 1.44 million dots makes focus operation intuitive and instant. You can simply touch the monitor screen to specify a desired focus point with Touch Focus. Also, Touch Pad function lets you drag the focus frame to another point with a fingertip on the LCD screen as you monitor the shot through the viewfinder.
Enhanced flash compatibility
The α7R III has new sync terminals, so non-dedicated flash units and cables with standard sync terminals can be connected for convenient synchronisation with studio flash units, etc. Release time lag when shooting with flash is minimised for smooth, responsive flash photography. Continuous flash shooting at up to 10fps offers advanced capture capability. To enhance versatility further, slow sync and rear curtain sync can be selected when shooting with wireless off-camera flash.
Clear, natural, realistic 4K movies
For high-resolution 4K movies33 with minimal moiré and jaggies, Super 35mm mode with full-pixel readout without pixel binning condenses approximately 1.8 times the amount of data required for 4K movies (QFHD: 3840 x 2160). Advanced image processing makes it possible to record full-frame 4K movies with dramatically improved image quality in the mid-to-high ISO range, so you make the most of the 4K movie format’s unique potential in every shot.
One-touch remote & One-touch sharing
One-touch remote can turn a smartphone or tablet into a viewfinder/remote control. One-touch sharing transfers photos/videos to your device for SNS sharing. Just install a PlayMemories Mobile app via Wi-Fi to your NFC-enabled Android device, and then touch the device to the camera to connect them. If you don’t have NFC, use QR code compatibility to pair the devices.
