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'...
