Welcome, David. As Akiva said, participate and enjoy yourself.
Your KP has the KAF2 mount, which means you can buy for peanuts some excellent full frame film cameras to use with your lenses. I have the MZ-5 which I bought for the princely sum of USD$4 at a thrift store, and it's a fine camera, very compact, supporting manual and auto-focus lenses and Manual, Shutter-priority and Aperture-priority exposure, with a large exposure compensation dial on the top deck. So if you want to play with film, you can do so for effectively zero upfront cost. Just sayin'...
just give me good light and a roll of film
