The Mamiya RB67 Pro-SD, introduced around 1990, is the last member of the RB67 family and the definitive version of Mamiya's all-mechanical rotating-back 6x7 cm medium-format SLR. The Pro-SD designation signals compatibility with Mamiya's K/L series lenses (also used on the RZ67), which feature a larger throat diameter and improved optical designs over the earlier RB lenses. The camera retains the core RB67 architecture: a bellows-focus body with no mirror pre-fire mechanism, a leaf shutter in each lens (allowing full-speed flash sync at all shutter speeds), and the signature 90-degree rotating film back that lets photographers switch between portrait and landscape orientation without turning the camera body. It runs entirely without batteries, making it immune to cold-weather battery failure and requiring no electronics for basic operation.

The RB67 family traces its origins to 1970, when Mamiya introduced the original RB67 as a direct competitor to Hasselblad in the professional studio market. The rotating back - allowing the film plane to rotate rather than the photographer having to cant the entire heavy camera body - was the system's defining innovation. The Pro (1974) and Pro-S (1974/1975) followed with incremental refinements to the film advance and shutter coupling. The Pro-SD arrived as Mamiya was also developing the electronically controlled RZ67, and its K/L lens throat was partly a rationalization move to share optics across both systems. K/L lenses fitted the Pro-SD natively; older RB C and KL lenses required an adapter ring but remained functionally compatible. The Pro-SD was produced into the 2000s and remained a popular studio rental camera well after digital medium format began displacing film in commercial work.
The RB67 Pro-SD represents the apex of a design philosophy that prioritized mechanical reliability and optical quality over electronic sophistication. The full-speed flash sync at 1/400s - a direct consequence of using leaf shutters in each lens - made the system uniquely suited to high-powered strobe lighting in studio portraiture and commercial still-life work. This kept the RB67 in active professional use long after cameras with faster top shutter speeds but focal-plane shutters had overtaken it in other genres. The format itself - 6x7 cm, nicknamed the "ideal format" for its close approximation to an 8x10 print aspect ratio - meant minimal cropping for standard print sizes. The all-mechanical construction made it a trusted camera in rental houses, where repairability and resistance to electronic failure outweighed the inconvenience of its considerable size and weight.
Native mount: Mamiya RB bayonet. K/L lenses were purpose-designed with improved multi-coating and larger elements suited to the 6x7 image circle. Key focal lengths include the 90mm f/3.8 KL (standard for portraits), 127mm f/3.8 KL, 65mm f/4.5 KL (moderate wide), and 250mm f/4.5 KL (long portrait). Earlier C and KL lenses mount with an adapter ring and remain optically excellent, though older coating designs show more flare with backlight. The rotating 120 film back is the system's most important accessory; Polaroid backs and 220 backs were also available. Prism finders with and without built-in meters allow eye-level use. A motorized film advance was available but battery-dependent.
