Mamiya RB67 System

The Mamiya RB67 is an iconic Japanese medium format 6x7 SLR. The name RB67 gets its name one of its defining features; a Rotating Back. This ingenious design allows for portrait or landscape shooting without rotating the camera. The viewfinder is a 7x7 square and has lines to reflect both orientations. The RB is a fully mechanical system that does not require batteries to operate, which is one of its biggest advantages over the newer RZ67.  Mamiya produced many different lenses for the RB67, all of them excellent. Lenses are equipped with leaf shutters with speeds ranging from 1 second to 1/400s. There are also interchangeable finders, grips, film backs, and other accessories that make the RB67 a truly modular camera.
