Mamiya RB67 Professional SD (1990)
A modular medium format SLR film camera with a 6x7cm image format. Introduced in 1990, fully mechanical, built for studio and field use.
Overview
The Mamiya RB67 Professional SD is a medium format single-lens reflex (SLR) film camera body made by Mamiya. It was announced in 1990. It is fully mechanical and built for durability and precision, and it was commonly used in studio and field photography where reliability and image quality are critical. The camera produces 6x7cm images and is modular, with interchangeable film backs and viewfinders. It has a new, larger lens throat compared to earlier RB67 models, so older lenses need an adapter.

Design

The catch is that older RB67 lenses need an adapter to mount. The camera is built for stability and precision in professional studio and field work.
Context
Announced in 1990, the RB67 Professional SD is a later evolution of the RB67 series, following earlier models like the RB67 and RB67 Pro. It was developed to improve usability and compatibility within a modular system, and it kept the series' reputation for sturdy construction and high image quality. The larger lens throat sets it apart from its predecessors and is the key update in the product line.
Market
A pre-owned Mamiya RB67 Professional SD body-only unit was listed for EUR 473.00, with EUR 20.00 for postage and packing. Based on owner estimates, a complete setup with a 90mm f/3.5 lens could fetch between $800 and $1,000 depending on condition. Some users note the camera's size and weight, and say it often needs a tripod for stable operation.
