Sony A9

Sony A9 was announced on 19th April 2017. This full-frame mirrorless camera comes with a 24.2 MP 35.6 × 23.8mm Exmor RS CMOS sensor. Sony A9 is considered as the first flagship mirrorless camera of Sony that can compete with Nikon and Canon flagship DSLRs like Nikon D5 and the Canon EOS-1D X Mark II. The camera is intended for professional photographers and obviously, it comes with a high price tag.
