Sony Alpha a7R IV A Full-Frame Mirrorless Camera Body (ILCE7RM4A/B)

The a7R IV A Full-Frame Mirrorless Camera features a 60MP full-frame back-illuminated CMOS sensor that offers a remarkable resolution and outstanding details. The Sony Alpha a7R IV A has a powerful, high-speed BIONZ X image processing engine that offers sharp, high-contrast images with accurate color reproduction even in low-light conditions. It also includes a built-in 5-axis image stabilizer for minimized vibration, Superb AF coverage, speed, and tracking, Real-time Eye AF, up to 10 fps burst shooting for capturing decisive moments, and much more.

61MP Full-Frame Sensor

The a7R IV features a 35mm full-frame back-illuminated CMOS image sensor with 61MP effective pixels that deliver sharp details and accurate colors. The back-illuminated structure and effective area-specific noise reduction techniques combine to produce an excellent blend of low noise and high sensitivity for enormous imaging potential.

15-Stop Dynamic Range

The Alpha 7R IV A has a 15-stop dynamic range at low sensitivities, which results in smooth natural gradations ranging from deep shadows to highlights, and uses algorithms from several Alpha cameras to maintain outstanding color reproduction.

BIONZ X Processing

Sony’s BIONZ X image processing engine features Advanced Detail Reproduction Technology and Area-specific Noise Reduction. They have been tuned to maximize the performance of a sensor. The sensor offers approximately 1.5 times more resolution than the highly acclaimed Alpha 7R III, producing extremely fine, realistic reproduction of textures and details.

Low Noise at High ISO

Achieve optimum image quality in just about any light, a standard ISO range that extends from ISO 100 up to ISO 32000 with undiminished quality is expandable to ISO 50 to ISO 102400 for still images. Noise is effectively reduced even at high sensitivities, maintaining outstanding image quality even with this sensor’s high pixel count.

16-Bit Processing and 14-Bit RAW Output

Image sensor output is processed in 16-bit form by the front-end LSI and BIONZ X image processing engine before being output as compressed or uncompressed 14-bit RAW files for overall high image quality. 14-bit RAW output is available even when shooting in silent or continuous mode.

Speed Up to 10fps with AF/AE Tracking

Thanks to the advanced mechanical shutter unit and updated image processing algorithms, you can now shoot full 61MP resolution images at up to 10 fps with continuous and accurate autofocus and auto exposure (AF/AE) tracking for up to approximately seven seconds in JPEG and RAW, and approx. three times as long in 26.2MPii APS-C crop mode. These high-speed options ensure that fast-moving subjects can be captured with accuracy image detail.

4D FOCUS

The Alpha 7R IV A's new image sensor features 567 phase detection points in a high-density focal plane phase-detection AF system, covering approximately 99.7% of the image area vertically and 74.0% horizontally. High-density focal plane phase-detection operates with 425 contrast AF points in a Fast Hybrid AF system that can handle a huge volume of data at high speed, snapping rapidly into focus with just about any subject and situation. Tracking performance has been improved to capture fast-moving objects.

Real-Time Autofocus Tracking

Track moving subjects when shooting stills or movies, with the Real-time Tracking that employs artificial intelligence to tenaciously track moving subjects.
