The Gemflex or Gem Flex is a subminiature twin-lens reflex camera made by Shōwa Kōgaku Seiki (昭和光学精機)[1] in November 1949. (It was advertised in Japanese camera magazines dated February to June 1950.)

The Gemflex uses paper-backed 16mm film, for a frame size of 14×14mm. It has the same layout as that of a conventional 6×6 TLR, with the viewing lens above the taking lens. It is a genuine TLR, with the viewing and taking lens moving together. The taking lens is a 25mm f/3.5 "Gem". The shutter has three speeds (25, 50, 100) as well as bulb. Film wind and focusing knobs are on the right.

The nameplate reads GEMFLEX with the "G" and "F" larger than the other letters. At the center of the outer cover of the viewing screen (visible from the front when the cover is open for use) is a stylized "SK" monogram.

A 1950 advertisement[2] does not mention the manufacturer but describes the camera as being distributed by Miura Shōji (三浦商事), of Ginza.
