Mamiya C330 Professional

The Mamiya C330 Professional is a twin-lens reflex (TLR) camera that is unique for its interchangeable lens system. Producing 6x6cm images on 120 film, it employs a bellows focusing system that allows for exceptionally close minimum focusing distances. The C330 features a cocking mechanism that automatically sets the shutter when the film is advanced, a refinement over the earlier C220 series. It is a purely mechanical camera, valued for its reliability and the quality of Mamiya Sekor TLR optics. Key inspection points for the C330 include the bellows condition and the accuracy of the twin-lens alignment. The leaf shutters in the lenses should be tested for consistency, particularly at slow speeds. We check the film advance and automatic shutter-cocking linkage for smooth operation. As with many TLRs of this age, the light seals in the film chamber usually require replacement. The focusing racks should be checked for even movement to ensure the lens board remains parallel to the film plane.
