Mamiya RB67

Mamiya RB 67 (Japan): first 67 medium format system SLR. Took ten exposures of 2¼×2¾ inch (6×7 cm) nominal frames (56×69.5 mm actual frames) on 120 film. Also had "revolving" rotatable interchangeable film backs to easily take vertical photographs with the normally horizontal format and standard interchangeable waist level viewfinder.
