[QUOTE="Horoscope Fish, post: 730121, member: 13090"] Ultimately only you can decide that for yourself. Personally, I check all my lenses for front/back focus. Some have needed adjusting, others have not. My personal opinion is that calibrating focus is definitely worth the effort. Specifics always depend on the lens in question. Nikon camera bodies only allow for a single, global adjustment for a particular lens, be it prime or zoom, so you have to use an averaged adjustment. Many (but not all) Tamron and Sigma lenses are able to use their respective "docks" which allow for correcting front/back focus at various distances and focal lengths. [/QUOTE]
