Looks like you got the lens for the ME-F (or whatever it was called), the first Pentax AF camera. It was an ME Super with extra contacts that used that lens. While it will mount on current Pentax AF cameras, I believe that it will only function as a manual focus lens.
Other questions about its operation I can't answer, unfortunately, as I've only ever handled that lens once, for five minutes or so, about ten years ago. :) -Aaron - This message is from the Pentax-Discuss Mail List.
