Hmm, haven't had my Pentax K-m for even a mont and I've already had to satisfy my LBA by buying a Pentax-M 50mm f/1.7.

Got it from a guy that had bought a N**** D60 because the salesperson told him that he couldn't use his old lenses on a new Pentax DSLR that he had originally wanted to buy.

Oh well, at least I got a fast fifty for a good price.
Just came back and it's dark outside, so I've only shot some test pictures.

Taken using my DA L 18-55 f/3.5-5.6
