i'm not really sure where to post this... but it had to do with my lens, so i guess i should post here. So today i was walking down the street with my camera in hand and saw a bird i wanted to take a picture of. i held the camera up to my eye and peered through the view finder. i pressed the shutter half way down and noticed the whole image shifted diagonally in my view finder when the lens autofocused. I reattched my lens and everything was fine (i missed the bird D:!!). Probably shouldn't have done so but ilightly shook the camera with the lens on it sounded like something was loose. maybe it always made that noise and i'm just being paranoid, but is there anythign wrong with my lens or camera? D60 + 18-55mm VR kit lens btw.
