Super 35mm 4K with clean low light up to 12,800 and EOSHD Pro Color, as well as S-LOG 2 and 3
Superb autofocus for stills
1D X Mark II style ergonomics but with an EVF and articulated screen making it much nicer to shoot video with
Much smaller 4K file sizes than the 1D X Mark II and 5D Mark IV
Superior resolution stills at 42MP vs 12MP (A7S II) and 24MP (A9)
5 axis image stabilisation vs none on the Canon 1D X Mark II
Make use of the lovely Sony A-mount range of lenses
