The Sony α9 (the α is sometimes spelled out as Alpha), Model ILCE-9, is a full-frame mirrorless interchangeable-lens camera. It was Sony's flagship camera as of 2017. The camera is not the successor to the α7 line of digital cameras but supplements it. Announced on 19 April 2017, the α9 is characterized by Sony as a true professional mirrorless camera system.[2] The α9 is being compared with the Nikon D5 and the Canon EOS-1D X Mark II.[3]

The headline feature of the α9 is the 20 frames per second with a buffer of 240 raw or 362 JPEG images. This is accomplished without temporarily blacking out the finder for each exposure, unlike a DSLR.[4]
The Sony α9 II, announced in October 2019, succeeds the α9. The new camera has updated ergonomics, connectivity, and a faster 10 fps burst with the mechanical shutter.[5]
