Shouldn't a lens be good or bad independently of the camera it is used with?
After seeing these reviews at DxOMark I got confused. By changing the camera where the lenses are tested I get different scores. I'm not talking about DX vs FX, because for sure something must differ from a full-frame to a cropped frame. But a score changing from a D5000 to a D7000 to a D90... why?
What is the influence of the camera on the image quality and performance of a lens?
