Autofocus can play up sometimes or take a few seconds, when it does that just use the manual focus first to then switch back and it sorts itself out. Cosmetic damage as seen in photos but there is no mould or dust in optics as far as I can see and displayed in photos. Comes with tripod foot and a lense cap -that falls apart sometimes but still works- aswell as a rear lense cap. Used for sports photography (with the autofocus) for a while and got some very nice shots so still has some life left in it for sure.
