I recently bought a Rollei Sl35ME and I had been looking for some time for a Rollei 35mm SLR. Now that I have one, finding lenses for it is proving to be hard. So I thought, Ok I'll be a Leica R3 or R4 - but there are no lenses to be found from KEH and the like (not a fan of EvilBAY). I want to log in to a site, do a search and buy a camera and lens - it seems suddenly a lot of gear has disappeared.

Where are all the Rollei, Contax and Leica bodies and lenses?
