(It requires a Nikon body with a built in motor not the D D, D unfortunately its manual focus only with these) Live view auto-focus is not available only manual.The auto focus is fast for this type of lens and the optics are excellent, being a prime lens you haven't got loads of elements collecting dust. There will be the odd speck of dust but nothing significant. The optics are free from scratches. The rubber coating has some marks these do not effect the operation of the lens in any way and there are some scratches near the tripod mount screw (see pictures).You can remove the tripod mount if not required for hand holding. Auto focus is speeded up with the focus limiter (see picts)The length of the lens doesnt increase when focusing and the close focusing is excellent.This lens gets loads of mentions on the internet for its image quality (have a look)Specifications:Get close-up shots even when you're physically distant.
