Pentax SMC 67 105mm 2.4 lens made for the Pentax 67 camera, but I'm including the Fotodiox Pro PT67 - PT645 adapter so it can be mounted on a Pentax 645 if you would like.  That adapter is worth around $100.  Also including the PH-SB 67 lens hood with case.  Everything in great shape and this copy of the lens is super sharp.
