Photonstophotos published their Sony a9 test results with some comparison data from the Canon 1D X Mark II and Nikon D5 cameras:
Photonstophotos updated their Sony a9 results with final data and it performs very well against its competitors up till 3200 ISO, where the Nikon D5 just edges it out. It’s good to see that the electronic shutter of the Sony a9 doesn’t affect the dynamic range of the a9 much according to Photonstophotos’ results. The Sony a9, beats the Canon 1D X Mark II across the board, but falls just behind the Nikon D5 in low light, while besting it in maximum dynamic range. (SonyAddict)
