I just purchased this lens to replace my kit lens over a week... I've played around with it a lot, but I've gotten much more missed focus photos then I did with my kit lens, some photos look perfect and some look totally missed focused.
Is there any way I can test the lens b4 I return the lens other then keep shooting? I just started shooting with DSLR for 2 months, so it's hard for me to tell that it's my skills or it's the lens that missed focus the photos.
(I don't think it's the camera because it's focusing great with kit lens) I am wondering if there is any testing technique that I can confirm that the lens is defective? Because I only have 2 weeks if I want to get my money back... @_@
