A few weeks ago I was looking for a fast 50mm to play with on my K100D, and it turned out that the cheapest way to get one was attached to an old film body. I bought a Ricoh KR-5 Super II primarily for the 50mm f/2 attached, but ended up putting a roll of film in just to try it. Fast forward a few rolls and the K100D spends most of its time in the bag while I am having more fun that I've had in a long time with cameras with the Ricoh. I really enjoy the mechanical action and the way that I am in no way limited by the capabilities of my camera. That said, the Ricoh feels a little plasticky and I would love a power grip option and depth of field preview. I have looked back through the Pentax manual SLRs and it seems an MX might be the perfect camera. I can't decide if the MX will really heighten my zen hippie retro photo experience or if I'm just GASsy- what do you guys think? Will the MX be more satisfying?
