Sony Alpha ILCE-7RM4A Full-Frame 61.0MP Mirrorless Digital SLR Camera Body

Ever more inspiring

Enter a whole new world of photographic expression with incomparable image quality and processing speed. A powerful new choice joins the α7R series with ever more advanced connectivity and enhanced reliability demanded by pros.

Unimagined subtlety

61.0-megapixel11 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 α7R IV captures the mood of each scene and the texture of aimed subjects.

61.0-MP11 full-frame back-illuminated CMOS sensor

The newly developed Exmor R CMOS image sensor boasts incomparable high resolution. Back-illuminated design exhibits high sensitivity and low noise, despite extremely high pixel count of 61.0 MP

The latest image processing engine

The latest BIONZ X image processing engine works in tandem with front-end LSI to maximize high-resolution sensor performance while achieving up to 15-stop12 dynamic range at low ISO sensitivity.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-stop12 dynamic range at low ISO sensitivity.

Wide standard ISO 100-32000 range

Regardless of increased pixels, the α7R IV full-frame mirrorless interchangeable lens camera delivers highest standard ISO 3200013 and reduces noise in the low- and mid-sensitivity ranges, achieving high-quality imagery.

Factors maximizing superb resolution

In-body 5-axis image stabilization

The in-body 5-axis image stabilizer algorithm is optimized to maximize high-resolution 61.0-megapixel11 image sensor performance. This fully supports your handheld shooting for reliability as effective as 5.5-stop14 higher shutter speed.

Shoot in absolute silence

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 maximizes extremely high α7R IV resolution for crisp clear images.

Blur-reducing structure

A re-examined and redesigned mechanism infixes the shutter unit to suppress subtle camera shake and enhanced image stabilizer algorithm effectively reduces image blur. Overall, the camera's high resolution is successfully maintained.

Shake-free remote shutter release

Remote camera operation using optional wireless remote controller (RMT-P1BT) allows you to shoot effective stills while avoiding camera shake caused by pressing the shutter release. This maximizes the image sensor's high resolution.

The highest-level burst speed in its class

Regardless of remarkable image resolution, the α7R IV full-frame mirrorless interchangeable lens camera maintains its shooting speed of up to 10fps with a mechanical shutter (up to 8fps in live-view continuous shooting mode).17 This allows you to capture decisive moments—such as motion of wild animals—with subtle details m.

Useful 26.2 MP 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 to APS-C size. This means the α7R IV full-frame camera 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.
