An APS-C camera can only resolve so much,

Care to elaborate on that? I was doing the math the other day and came up with about 340 MP to fully resolve f/4 on a DX sensor versus 181 MP to fully resolve f/5.6 on an FX sensor, that is what would be required before a theoretically perfect lens would be diffraction limited.
