Both on the inside on the back element and correspondingly on the inside of the moving focusing lens group. It's almost certainly damage to the multicoating due to colliding elements. The focusing group physically stop in the glass of the back element. The lens is obviously out of alignment. - This message is from the Pentax-Discuss Mail List.
