About the Sony a7R IIIA Mirrorless Camera
The Sony a7R IIIA is a full-frame mirrorless camera featuring a 42.4-megapixel Exmor R back-illuminated CMOS sensor paired with the BIONZ X image processor, delivering high-resolution stills and internal 4K video recording with minimal noise. The camera offers a sophisticated autofocus system with 399 phase-detection points and 425 contrast-detection areas, enabling fast focusing speeds and reliable subject tracking down to -3 EV, along with an enhanced 5-axis image stabilization system that compensates for camera shake during handheld shooting.
The a7R IIIA captures continuous bursts at up to 10 frames per second at full resolution for up to 76 consecutive frames, with an expandable ISO range of 50 to 102,400 and the ability to record UHD 4K video at up to 30 fps using the XAVC S codec with optional S-Log3 and HLG color profiles for professional video work. The camera is constructed with a durable magnesium alloy chassis and weather-sealed design, incorporates dual SD memory card slots with UHS-II support, and includes modern connectivity options including USB 3.2 Type-C, Wi-Fi, NFC, and Bluetooth for enhanced workflow flexibility.
