Minolta's subminiature camera — the Minolta 16 for 16mm cartridge film.
The Minolta 16 is a subminiature 16mm film camera from Minolta, Japan's entry into the compact spy camera market of the 1950s–1970s. The Minolta 16 series produced multiple variants including the 16, 16P, 16PS, and 16MG over its production run.
The Minolta 16 uses dedicated 16mm Minolta cartridge film producing 10x14mm negatives, features a fixed or limited-aperture lens, and provides simple shutter operation in a very compact metal body. Specific lens and shutter specifications depend on the production variant.
Minolta's 16mm cameras represented Japan's quality-conscious approach to the subminiature format, competing with Western products like the Minox. The specific variant determines lens quality and feature set. Minolta 16 film cassettes are available from specialty suppliers though production has long ceased.
Identify the specific variant from physical markings (16, 16P, 16PS, 16MG). Test shutter and film advance. Inspect lens clarity. Film cartridges are available from specialty subminiature film suppliers.
