i was setting my Canon 100-400mm lens sharpness to suit my camera in the micro-adjustment function at 400mm end.
and i focus on different item at different distance.
most of the time it performs best at around +15.
however,there was an instance that 0 is sharper than the +15.
anybody can explain why is this so?
