61.0MP1 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 61.0MP1.

The latest image processing engine

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-stop2 dynamic range at low ISO sensitivity.

Wide standard ISO 100-32000 range

Regardless of increased pixels, the α7R IV delivers highest standard ISO 320003, and reduces noise in the low- and mid-sensitivity ranges, achieving high-quality imagery.

In-body 5-axis image stabilisation

The in-body 5-axis image stabiliser algorithm is optimised to maximise high-resolution 61.0-megapixel1 image sensor performance. This fully supports your handheld shooting for reliability as effective as 5.5-stop4 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 maximises 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 stabiliser 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 maximises the image sensor’s high resolution.

Useful 26.2MP 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 into APS-C size. This means the α7R IV 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.

Wide AF coverage

New image sensor supplies wide and high-density AF coverage with 567 phase-detection AF points (approx. 99.7% height and 74.0% width). 425-point contrast-detection AF supports precision focusing.

Fast AF despite higher resolution

Thanks to responsive enhanced Fast Hybrid AF, despite its large data handling, the α7R IV delivers swift AF even under dim lighting conditions, with remarkable ability to capture an aimed subject.

Steadfast AF tracking further improved

Increased AF points, widened coverage of AF sensor, and improved AF algorithm have further enhanced subject-tracking performance for consistent shooting, even of complex or sudden movements.

High-precision AF in underlit conditions

Advanced AF algorithms contribute to AF precision at light levels as low as EV-38. ‘Focus Priority in Aperture Drive’ option is for more accurate focusing in dim lighting and when aperture is stopped down.

Shoot up to 68 images continuously

Because buffer memory size is 1.5 times larger9, the camera maintains burst shooting speed of up to approx. 68 images10. With APS-C shooting mode, you can shoot approximately three times more photos than with full-frame shooting mode.

Dual media slots, both supporting UHS-II

Both SLOT 1 and SLOT 2 are compatible with UHS-I and UHS-II for fast mass-volume data writing. The α7R IV can simultaneously or relay record, separate RAW/JPEG data and stills/movies, and copy data between cards.

Extend shooting to professional length

The α7R IV uses a high-capacity NP-FZ100 battery. For longer hours of shooting, combine this with optional VG-C4EM Vertical Grip holding up to two NP-FZ100 batteries, which allows you to shoot two times more shots than with α7R IV.
