Sony Alpha 7R IV Full-frame Mirrorless Interchangeable-Lens Camera

Thanks to an evolutionary leap in image processing power and efficiency, the Alpha 7R IV combines world’s first1 high-resolution 61MP2 back-illuminated Exmor R CMOS image sensor with impressive shooting speeds at up to 10 fps4 with full AF/AE tracking, as well as beautiful 4K8 HDR video, wide 15-stop3 dynamic range and high sensitivity with area specific noise reduction.

World’s first1 61MP2 pixels full-frame sensor

The Alpha 7R IV features the world’s first1 35mm full-frame back-illuminated CMOS image sensor with 61MP2 effective pixels, delivering depth and dimension that was once only available in medium-format cameras. The back-illuminated structure and effective area specific noise reduction techniques combine to deliver an extraordinary blend of low noise and high sensitivity for enormous imaging potential.

15-stop3 dynamic range

The Alpha 7R IV boasts an impressive 15-stop3 dynamic range at low sensitivities, resulting in smooth natural gradations ranging from deep shadows to highlights, and utilizes algorithms from many of the latest Alpha cameras to maintain outstanding color reproduction.

BIONZ X processing maximizes sensor potential

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

Low noise at High ISO

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, make it possible to achieve optimum image quality in just about any light. Noise is effectively minimized even at high sensitivities, maintaining excellent 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 that have smoother, more natural gradations for higher overall image quality. 14-bit RAW output is available even when shooting in silent or continuous mode11.

Real-time Eye AF

Real-time Eye AF employs artificial intelligence to detect and process eye data in real time, and track the subject’s eye with unprecedented precision. This function can be activated via an assigned custom key, or by simply pressing the AF-ON button or half-pressing the shutter button. When used with the Real-time Tracking function, tracking will continue even if the camera is temporarily unable to locate the subject’s eye, so it is easier than ever to shoot dynamic portraits of moving subjects. 

4D FOCUS – Wide, fast, reliable AF gets the shot

The new image sensor in the Alpha 7R IV 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 works 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.
