Mamiya Mamiyaflex PF (1957)
The Mamiyaflex PF is a medium-format twin-lens reflex camera marketed in 1957 and built for police use. The "PF" reportedly stands for "Police Flex." Mamiya designed it as a forensic and academic tool with reduced magnification, meant to make 1x (life-size) photographs for evidence documentation. In the company's TLR lineup it sits between the Mamiyaflex Automat A II (1954) and the Mamiyaflex C2 Professional (1958).
The record is thin from here. No lens specifications, shutter speed ranges, dimensions, or focusing system details survive in the available documentation. The camera uses a leaf shutter, and one source notes both manual and automatic focus options, though it says nothing about how those worked on this model. Film transport is listed as "internal power drive." That's unusual for a TLR of this era, but details are scarce.
This was a specialized instrument, not a general consumer camera, which likely explains both its obscurity and its collector appeal. Prices vary by condition, running from roughly $500 to $1500 USD. Japanese dealers like Fujiya Camera maintain buyout/appraisal pages for it, which points to steady secondhand trade in its home market.
Known specs, such as they are:
- Medium-format TLR camera, 120 film
- Marketed 1957
- PF = Police Flex; forensic/academic use with reduced magnification for 1x photos
- Leaf shutter mechanism
- Film transport: internal power drive
If you own one and can fill in the lens or shutter details, the archive would be glad to hear from you.
