The Prismat NP is an early interchangeable lens 35mm SLR camera from Mamiya released in 1961. The body does not have any marking for the model name. It has a horizontal traveling cloth focal-plane shutter with speeds from 1 to 1/1000, plus B. It has FP and X synchronisation terminals on the rear, and a self timer. The lens has an Exakta bayonet mount. This has been modified with a sort of "reverse PAD" mechanism where firing the shutter causes a small pin to emerge from the camea body and engage with a stopdown release on a lens outrigger. Some examples come with a Canon OM 50 mm f/1.9 lens with a semi-automatic diaphraphm, as illustrated below.
Versions of this camera were also distributed by Sears as the Sears 32B, Tower 32A, Tower 37A and Tower 32B.
In 1962 this camera would become the basis of the Argus (SLR) (with a different lens mount) and the Nikkorex F (restyled and with a new Copal shutter). The Nikkorex F also had a second life as a rebadged and modified camera sold by various department stores.
