The lens most likely was made to work as an autofocus lens with a very specific camera . . . I forgot the model offhand (ME-F?), but know it's mentioned on Boz's site.
This was Pentax's rush into autofocus, and placed the motor in the lens instead of in the camera body . . . . . . Needless to say, the design was short lived and I believe this and a 50mm lens were the only two produced. The lens should work fine as a manual focus lens though.
