Sony Alpha a7R IV Mirrorless Digital Camera Body
Unimagined subtlety
The 61.0-megapixel 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 subjects.
The latest image processing engine
The BIONZ X image processing engine and front-end LSI to maximize high-resolution sensor performance and up to 15-stops
of dynamic range.
Wide standard ISO 100-32000 range
Regardless of increased pixels, the α7R IV delivers the highest standard ISO 32000
and reduces noise in the low- and mid-sensitivity ranges, achieving high-quality imagery.
In-body 5-axis image stabilization
The in-body 5-axis image stabilizer algorithm is optimized to maximize high-resolution 61.0-megapixel
image sensor performance. This fully supports your handheld shooting for reliability as effective as 5.5-stop 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. A vibration-free shutter maximizes the extremely high α7R IV resolution for crisp clear images.
Blur reducing structure
To maximize the incredible resolution available to the α7R IV the tiniest vibrations need to be suppressed — Sony re-engineered the shutter unit assembly with dampened screws to absorb any shutter shock. Combined with an enhanced image stabilizer algorithm, blur is dramatically reduced, and pin-sharp detail is reliably captured.
Shake-free remote shutter release
Remote camera operation using the 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 maintains its shooting speed of up to 10fps with a mechanical shutter (up to 8fps in live-view continuous shooting mode).
This allows you to capture decisive moments—such as motion of wild animals—with subtle details made possible only by the 61.0 MP high-resolution imaging capability.
Useful 26.2 MP with APS-C cropping
Thanks to extraordinary image resolution, you can still maintain remarkable high-resolution images at approximately 26.2 megapixels even after cropping a full-frame image down to APS-C size. This means the α7R IV can help you proactively utilize 61.0-megapixel full-frame shooting, for example, in bird photography that tends to require cropping editing to magnify captured images.
