Sony a7R IV A
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.
61 MP 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-stop dynamic range at low ISO sensitivity.
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.
Technology basis for Real-time Tracking
Sony's original AI (Artificial Intelligence) subject recognition technology and algorithm process large-volume data captured by the image sensor in real time, tracking moment-to-moment subject changes with a high degree of accuracy. Color, pattern, subject distance, human face and eye information are used for highly accurate subject recognition.
Real-time Eye AF with animal eye tracking for more success
Thanks to an improved algorithm, the α7R IV now supports animal eye in addition to human eye tracking, allowing fast, precise, automatic detection and tracking. This animal eye support will greatly increase your success in capturing images of animals in the wild or favorite pets at home when an obstacle comes into view or the camera's horizontal/vertical orientation often changes.
