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-stop dynamic range at low ISO sensitivity.
Wide Standard ISO 100-32000 Range
Regardless of increased pixels, the α7R IV delivers the highest standard ISO 320005 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.
Blur Reducing Structure
A re-examined and redesigned mechanism infixes the shutter unit to suppress subtle camera shake and an 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.
5.76-million-dot UXGA OLED Tru-Finder
This 5.76-million-dot electronic viewfinder reproduces fine detail with approximately 1.6 times higher resolution than α7R III. You can select "High" quality mode for high-precision yet natural realism while suppressing moiré and jaggies for better concentration. Smoother image with a 120/100fps frame rate makes it easy to track moving subjects
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).9 This allows you to capture decisive moments—such as the 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.
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 Low-light Conditions
Advanced AF algorithms contribute to AF precision at light levels as low as EV-310. The ‘Focus Priority in Aperture Drive’ option is for more accurate focusing in dim lighting and when the aperture is stopped down.
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 the 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.
