So, I'm thinking about maybe buying a Mamiya RB67. I've read some stuff but I'd like to hear from some of you who have one or did what you think I should be looking out for in the used market. I don't want to put too much money into the camera so I'm looking for the body, one lens, a WLF, and back. I'll shoot mostly in landscape orientation so the rotating back isn't necessary unless the price doesn't increase too much by having it. Lens-wise, Maybe 35mm equivalent, or something mid-tele--85-100 equivalent. If I can find one here in the states that would be great, but I don't mind buying from Japan--I often do. Oh, I like to shoot polaroids so a polaroid back would be cool--how much of the film is exposed? Anyway, LMK what you think. Thanks!
