Mamiya Prismat CPH image by David Sides (Image rights)

The Prismat model CPH from Mamiya revises the earlier Prismat PH by replacing its selenium meter with a new CdS cell just under the rewind crank. This remains a behind-the-lens leaf shutter SLR with a proprietary mount, allowing optional 38mm or 100mm lenses to replace the standard 48mm f/1.9 Mamiya/Sekor.

A match-needle indicator is visible in the viewfinder, requiring a 1.35v mercury battery (no longer available) to operate. Film ASA sensitivity is set on a small front-facing dial, and the leaf shutter permits speeds from 1 to 1/500 sec. to be selected.

This model is evidently uncommon enough to be absent from McKeown's 12th edition.
