Originally posted by krazny I am sort of curious how you came to the conclusion that your lenses were K-mount. None of my K-mount lenses has the letter K on it except for my Tamron 17-50 has KPR written on the rear lens cap.
I searched up the lens and the Pentax forums lists it as such

Overall, it has been a headache trying to find these lenses listed accurately at all, even when searching for the exact lens. I'm not super familiar with older lenses and the fact that they all just kind of came in a plastic basket with no paperwork or ID aside from what is on the lens hasnt helped identify what I need to be able to use them
