Say an APS-C DSLR fitted with a 200mm lens vs a FF DSLR with the same 200mm lens.
Assuming that both camera's AF has similar performance and sensitivity.
Will it be easier for the APS-C DSLR to focus on far targets compared to the FF? Since the subject will appear 50% bigger on the APS-C, does this help the AF of the camera? Or is there no difference at all?
