Yes. Cheap. It's a lousy lens. LNIB Samyang 500mm F8 "T" mount mirror lens with Pentax K mount and a LN M43 mount. The lens box is a little banged up but the rest is very nice. Lens carry strap is still in its little poly bag and the two accessory ND filters are in theirs. I bought this lens locally on CraigsList then dropped another $30 into an adapter. What I found is that the lens is very soft. Fun to play around with but not for serious photos. I also discovered that 1000mm equivalent focal length almost requires a tripod, at least on a Panny body. An Olympus body might do better. I don't think the softness is a mechanical issue with my camera, though I might be wrong. Just looking at the lens it seems to be perfect, no clouding, fungus, scratches, etc. No rattles. It just isn't sharp. So ... for $45 + shipping you can play around with a 500mm lens. Just don't come back to me and complain that it's not a very good one!
