The Sony Alpha 9 (a9) is a new digital 35mm full-frame camera from Sony, boasting a 24.2MP CMOS sensor. The mirrorless camera offers 4K (3840 x 2160p) video recording across its full sensor.
Approximately 25% faster performance when compared with the α7R II.
The camera uses full pixel readout without any pixel binning to snag 6K of information. This means that Sony is oversampling to produce its 4K footage to provide more detail and depth to the image. You can also record in the popular Super 35mm size, and, as you might expect, the a9 can record full HD at 120 fps at up to 100 Mbps.
The 24.2 MP full-frame CMOS sensor is back-illuminated, allowing it to capture maximum light. Its ISO range is 100 – 51200, expandable to 50 – 204800, while its enhanced BIONZ X processor plays a large part in image quality to minimize noise in the higher sensitivity range. What's more impressive, the a9 now supports uncompressed 14-bit RAW, so we can now get the most out of its wide dynamic range.
