Sony Alpha a7R III A Full-Frame Mirrorless Camera Body (ILCE7RM3A/B, New Version)

The Sony a7R III A achieves outstanding resolution, sensitivity, dynamic range, and provides the technical capability you need to let your imagination soar and fulfill your vision with breathtaking reality. The full-frame, mirrorless a7R III A will up your photography game without breaking the bank, and has a variety of connectivity features that offers the potential you need to explore worlds that have previously been beyond reach.

42.4 Effective Megapixel Full-Frame Exmor R CMOS Sensor

The Sony a7R III A features a back illumination for high sensitivity, gapless on-chip lenses, antireflective seal glass coating, no optical low-pass filter, and other unique features. The high resolution, high sensitivity with low noise and wide dynamic range add up to vastly expanded shooting potential.

High-Speed BIONZ X Image Processor

The BIONZ X image processing engine offers an increase in system speed, plus an impressive 15-stop dynamic range at low-sensitivity settings. Sony’s Detail Reproduction Technology has been updated with advances along with the Area-Specific Noise Reduction feature which can reduce noise by as much as a full stop in the mid sensitivity range. The combination of high resolution and low noise is ensured over a wide sensitivity range, for excellent image quality and color accuracy that is ideal for portraits and landscape photography.

Up to 10 fps with AF/AE Tracking

Thanks to the new shutter unit and image processing system refinements, the a7R III A is capable of shooting continuously at up to 10fps with AF/AE for easy, stable shooting of even intensely active subjects. An electronic shutter allows silent, vibration-free shooting when even slight noise can mean missing an ideal shot.

Advanced Autofocus

The a7R III A also autofocuses reliably down to EV-3 brightness. AF algorithms optimized for the a7R III A improve AF speed, precision, and tracking performance. 399 phase-detection AF points and 425 contrast-detection provide high-density wide-area coverage. The a7R III A also features Eye AF's enhanced precision, plus two times greater AF speed and AF tracking performance further assists you to easily shoot a portrait of a moving subject using AF-C even during continuous shooting. Focus information from the lens keeps AE control and image brightness consistent even when subject position or background brightness changes. The a7R III's E-mount body supports Eye AF for A-mount lenses mounted via an adaptor.

High-Resolution 4K HDR

The camera features a Hybrid Log-Gamma picture profile, supporting instant HDR workflow, that provides a wide dynamic range for highly precise and lifelike movie images without color grading.

Versatile Viewing

This high-resolution Quad-VGA OLED Tru-Finder has approximately 3.69 million dots. It provides outstanding details and high contrast for accurate black reproduction. The high luminance brings viewfinder brightness closer to that of the actual scene. The high quality of the viewfinder image and features like focus magnification make it easier to achieve perfect focus with just about any subject in any situation.

Wi-Fi and NFC Functionality

The Sony a7R III A offers a variety of controls and functions. With the one-touch remote, a smartphone or tablet functions as a viewfinder/remote control. You can easily share transfers photos/videos to the device with One-touch. Install the PlayMemories Mobile app on an NFC-enabled Android device via Wi-Fi. The Sony a7R III A provides features that will perfect and enhance your images. All of this comes in a compact package that is easy to use while seamlessly supporting professional workflows.
