I bought two lenses, one for the d60 and the other for the d7000. What is interesting is that on the d60 all instances were focused normally. On the d7000, all of these instances were in back focus. From which we can conclude that it is not the lenses but the camera that are probably to blame for the back and front focus. but everything was decided well, on the d7000 there is a focus correction in the menu. I really liked the spam lens, you can shoot in the dark with ISO 1600, no flash is needed. Chromatic aberrations are drastically reduced at f2.0 and sharpness is excellent at the same aperture.
