The new Alpha 9 from Sony is the first mirrorless digital camera featuring a full-frame stacked CMOS sensor.

Working in conjunction with the stacked CMOS sensor of 24.2MP is an apt BIONZ X image processor that ensures quick processing speeds to keep up with fast-paced shooting applications. Continuous shooting up to 20 fps is supported for up to 362 consecutive JPEGs, or 241 raw frames, along with a top electronic shutter speed of 1/32,000 for freezing fast-moving subjects or working in bright lighting conditions.

Benefitting the fast recording capabilities is an equally quick AF/AE metering system that functions at 60 times per second to continuously evaluate the scene in order to lock onto and track moving subjects. Additionally, due to the use of an electronic shutter, totally blackout-free monitoring is possible with the electronic viewfinder for more accurate compositions of moving subjects.

Covering 93% of the image area, a focal-plane phase-detection autofocus system incorporates 693 points along with 25 contrast-detection areas for quick and precise focusing in in a variety of lighting conditions with sensitivity down to -3 EV.
