I think I have 2 of those cameras. (Well not exactly sure about the AF-5 part.) I don't know much about them though, but I do have tons of accessories for them! LOL I do know that some of the Ricoh lenses will work on the newer Pentax DSLR cameras. It has to do with it having a K mount or not. (That's just what I read somewhere when I was trying to decide if I should go with a DSLR that would work with lenses I might already have.) I went with Nikon because I wasn't sure what I was doing. LOL
