Purchased new one year ago. This is an adapter for using Pentax K-mount lenses on L-mount bodies. I think I've used it about 10 times. There are no major scratches or stains on the exterior, but there are fine scratches and signs of use on the mount contact surface. From the time of purchase, there are several marks from a marker (like a Sharpie) inside the adapter, though it's unclear if this was for inspection purposes. There is no aperture ring, so aperture adjustment is required on the lens side. Also, AF is not available, only MF. Will ship in 2-3 days.
