When it comes to APS-C cameras things ‘seem’ to be going rather well. Newer APS-C cameras like the Sony a6400, and Fujifilm’s X-T3 are doing things that photographers never thought APS-C cameras would be able to do, but after four years, the Samsung NX500 still occupies the number two spot on DXOMark’s list of best performing (from an image quality stand point) APS-C cameras. Above it sits the Nikon D7200 which was also released back in 2015. How can this be? One has to wonder just what on earth is going on with APS-C sensors, and why haven’t things improved for four years when it comes to their overall image quality?
