Includes Sony Real-Time Tracking technology, winner of Best Photo Innovation in the TIPA Awards 2020.
Once locked on with a half-shutter press, Sony's Real-Time Tracking AF Technology tracks the subject wherever it moves within the frame.
With Real-time EyeAF (for humans and animals) the camera will automatically pick up and lock onto the eye of the subject, when visible in the shot. It's speed and accuracy helped it to be awarded with the Best Photo Innovation certification at the 2020 TIPA (Technical Image Press Association) World Awards 2020.
61.0-megapixel full-frame sensor
61.0-megapixel full-frame Exmor R CMOS sensor combined with BIONZ X imaging engine delivers unprecedented resolution, fine gradation, and low noise to open entirely new dimensions of detail just as pro photographers expect. The A7R IV A captures the mood of each scene and the texture of aimed subjects.
15-stop dynamic range
The latest BIONZ X image processing engine works in tandem with front-end LSI to maximise high-resolution sensor performance while achieving up to 15-stop dynamic range at low ISO sensitivity.
Useful 26.2MP with APS-C cropping
Thanks to extraordinary image resolution, you can still maintain remarkable high-resolution images as approximately 26.2 megapixels even after cropping a full-frame image down into APS-C size. This means the A7R IV can help you proactively utilise 61.0-megapixel full-frame shooting, for example, in bird photography that tends to require cropping editing to magnify captured images.
Real-time Eye AF
Real-time Eye AF represents the evolution of portrait shooting. This AI-aided technology provides immediate, accurate eye detection and tracking for crisp, clear focus on the subject’s face, even when capturing a fast-moving model in a photo session. The photographer can concentrate on composition — for smoother workflow that counts with pros.
4K movie recording
Full frame and Super 35 formats can be selected for 4K movie recording. Super 35mm mode can condense approx. 2.4 times the amount of data required for 4K movies (QFHD: 3840 x 2160), resulting in high-detail 4K with minimal moiré and jaggies. In either mode, the advanced image processing system delivers more accurate skin tones as well as smoother highlight gradations.
Dual card slots
Both SLOT 1 and SLOT 2 are compatible with UHS-I and UHS-II for fast mass-volume data writing. The A7R IV A can simultaneously or relay record, separate RAW/JPEG data and stills/movies, and copy data between cards. A slide lock structure prevents the memory card cover from being opened unintentionally.
Silent shooting not only provides a useful advantage in venues where quiet is required but avoids vibration that can cause camera-shake blur. Vibration-free shutter maximises extremely high A7R IV A resolution for crisp clear images.
5-axis in-body image stabilisation
The in-body 5-axis image stabiliser algorithm is optimised to maximise high-resolution 61.0-megapixel image sensor performance. This fully supports your handheld shooting for reliability as effective as 5.5-stop higher shutter speed.
