Sony Alpha a7R IIIA Mirrorless Digital Camera Body Only

Product Highlights

• Back-illuminated 42.4MP full-frame sensor : The 35mm full-frame Exmor R CMOS image sensor features 42.4-megapixel12 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 faster13 and the BIONZ X image processor is now about 1.8 times faster14. 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 output15 even during silent shooting/continuous shooting.
• A quantum leap in AF performance : 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 faster16 AF speed and two times more precise13 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 brightness17.
• 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 images21 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.
• Eye AF with doubled13 tracking performance : Eye AF’s enhanced precision, plus two times greater AF speed and AF tracking performance13 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 lenses18 mounted via an adaptor.
