A flagship in the truest sense, the Sony a1 is the one camera designed to do it all. Built without compromise, this full-frame mirrorless offers high-resolution for stills shooting, impressive 8K video recording, speed and sensitivity, and connectivity for the most demanding professional workflows.
Exmor RS Stacked Sensor and BIONZ XR Processor
50.1MP Full-Frame BSI CMOS Sensor and BIONZ XR
Newly developed 50.1MP Exmor RS full-frame sensor features a stacked back-illuminated design with integrated memory that maintains high image clarity, expandable sensitivity up to ISO 102400, and a 15-stop dynamic range while also enabling fast 30 fps shooting and and phase-detection AF. The sensor also enables recording lossless compressed raw files for flexible editing during post-production while maintaining a relatively lightweight file size. Additionally, the 50.1MP resolution not only benefits stills shooters as it also offers full-frame 8.6K oversampling for 8K video recording.
A revised BIONZ XR engine greatly benefits image processing capabilities throughout the camera system, including up to 8x faster processing, greatly reduced rolling shutter, and more fluent interface and file management handling speeds.

Pixel Shift Multi Shooting
This unique compositing mode allows you to achieve even greater resolution than the 50.1MP sensor affords. Working in conjunction with the sensor-shift image stabilization, this mode shifts the sensor while making 16 consecutive exposures in order to acquire approximately 199MP of information for greater color accuracy and detail than possible with a single exposure. These files can then be merged together during post-production by using the Sony Imaging software suite.
