The full-frame image sensor in the α9 employs a stacked structure designed specifically for high speed. The combination of advanced sensor and evolved BIONZ X processing enable continuous shooting at up to 20 fps, blackout-free shooting, up to 60 AF/AE tracking calculations per second, silent vibration-free electronic shutter speeds up to 1/32000 sec., Anti-Distortion Shutter operation that minimizes distortion of moving subjects, and other capabilities that add up to unprecedented speed from a full-frame camera without interference from mechanical devices.
