Longko,
this lens I think is to be used in Mode K10 d. I don't think there is electrical contact on the lens with K10D. Hence aperture priority or shutter priority cannot be used. The lens is made by Kiron. I think I email him with regards to A lens of pentax. Anyway, it makes no difference to you, if you are a manual man, your skill............
Another one vivitar 105 f2.5 or 2.8 is up for sale by Jim Trader and I paid also 315 us including shipping, this morning. Old inventory but new lens. I think new stock is coming in

By the way, I offered 180 us and he got back to say all four have already been taken and this offer cannot be accepted but thru another email informed me that he has new stock coming in and he will accept 180 from me. I paid thru pal-pal. My second time dealing with Jim Trader.
Dp preview reports does speak positive of this lens.
By the way, anyone want a local store, there is one in people's park center still having one for sale, magnificient photo, the one in a corner but asking 45X net. Can go there and test
