SMC PENTAX-M 40-80mm ZOOM ASAHI OPT CO JAPAN Macro Zoom Lens Thank you for viewing. This is a used item I purchased on Yahoo Auctions. I used it with a PENTAX K1. It's a 40-80mm manual zoom lens that can switch to macro from 80mm. It's an interesting lens because the focus ring moves up and down from the side when shooting in macro mode. I liked it, but I'm selling this lens because I'm getting rid of my Pentax body. The exterior has no major scratches, but there are signs of use and fine scratches typical of an old lens. There's no tab to rest your finger on when attaching the lens (it's not essential). I noticed this after using it for a while. It was missing from the time of purchase. The lens has some dust and particles. I don't think there's any mold, at least to my untrained eye. Size... Pentax K mount
