Sony Alpha a7R III Mirrorless Digital Camera (Body Only)
SKU # son.ILCE7RM3.B
α7R III 35 mm full-frame camera with autofocus
An entirely renewed image processing system further enhances image quality. Up to approximately 2x improved AF speed1, AF tracking2, and Eye AF tracking2 performance and up to 10fps continuous shooting allow more decisive moments to be captured. Reliable pro-style operability packed within a strong, compact body provides superior flexibility and mobility.
Back-illuminated 42.4 MP full-frame sensor
The 35 mm full-frame Exmor R CMOS image sensor features 42.4-megapixel3 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.
Further enhanced image processing engine
The latest front-end LSI makes data readout from the image sensor approximately two times faster2 and the BIONZ X image processor is now about 1.8 times faster4. 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 color has been dramatically improved, which is advantageous for portrait shooting. The α7R III also supports 14-bit RAW output5 even during silent shooting/continuous shooting.
A quantum leap in AF performance
An evolved image processing system and α9 camera. AF algorithms optimized 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 faster1 AF speed and two times more precise2 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 brightness6.
Eye AF with doubled2 tracking performance
Eye AF's enhanced precision, plus two times greater AF speed and AF tracking performance2 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 lenses7 mounted via an adaptor.
Focal-plane phase-detection AF supports A-mount lenses8
Phase-detection AF can operate even when an A-mount lens is mounted to the α7R III via an LA-EA3 adaptor that doesn't include a dedicated phase detection AF sensor. The 399-point focal-plane phase-detection AF system provides wide-area coverage, fast response, and high-performance tracking whether an A-mount or E-mount lens is attached.
Up to 10fps9 with AF/AE tracking
With new shutter unit and image processing system refinements, the α7R III can shoot continuously at up to 10fps9 with AF/AE tracking (up to 8fps9 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 images10, 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.
AF-ON button and multi-selector
The AF-ON button activates autofocus without any half-press-shutter-button focus sequence, so you can concentrate better on exactly when to release the shutter and capture the moment instantly. A multi-selector lets you shift the point of focus quickly and efficiently. You can select and shift the point of focus intuitively, so you won't miss great chances to shoot moving subjects.
Flicker from fluorescent and other artificial lighting is automatically detected and shutter action is timed to minimize the flicker's effect on still images. This suppresses exposure and color anomalies at the top and bottom of images shot at high shutter speeds, as well as exposure and color inconsistency between continuous shots, so you can take images indoors with more confidence.
In-body 5-axis image stabilization with up to 5.5-stop12 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-faster12 shutter speed, so the α7R III can take full advantage of its 42.4-megapixel3 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 Shooting13 opens a new world of resolution
Applying mechanisms and control technology of image stabilization, this new feature composites four separate pixel-shifted images that contain total data14 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 color, and realistic atmosphere, with minimal moiré and color artifacts. 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.
AE precision that's faithful to a photographer's intentions
A 1200-segment live-view exposure analysis makes color analysis and metering precise. Focus information from the lens keeps AE control and image brightness consistent even when subject position or background brightness changes. Highlight and Entire Screen Average metering modes now join the α7R III's Multi, Center, and Spot metering modes. When the Focus Area parameter is set to Flexible Spot or Expand Flexible Spot, the metering spot can be linked to the focus area.
Dual slots with UHS-II compatibility
This camera provides two media slots for SD card (UHS-II-compatible for fast data writing) and SD/MS card, respectively. Two cards in the slots can be used to simultaneously record or relay record data, separate RAW data from JPEG data, or stills from movies, and copy data from one card to the other. The memory card cover is lockable to prevent it from being opened unintentionally.
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 120/100fps15 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, the 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.
