Long time collector disposing of surplus and unwanted items from collection. Up for offer is a SMC Pentax-A f/2.8 / 28mm Wide Angle Lens. PLEASE NOTE: This is a manual focus lens. It works on AF cameras, but you must focus manually. Compatible with all Pentax DSLRs. Another K-mount lens, the Pentax-A series of lenses saw the introduction of "automatic" aperture settings. The lenses had an aperture ring (unlike the later DA series), and thus the aperture could be set manually, but they also had an "A" mode, which allowed the camera to control the aperture automatically.
