This is a manual focus lens – NOT auto focus. It has the AI-S lens mount / meter tab. The lens has ED glass and internal focusing. The lens is well used and has a couple of very small marks in the front lens element and some internal dust. Works well – a very sharp optic. Comes with the fitted Nikon hard case and the small internal filter and the lens carry strap. Big lens with a fast f3.5 maximum aperture.
