See also the Convex Reflex SLR camera.

The name Convex or Convex-Rapid is found on some Japanese leaf shutters of the 1940s and 1950s. All these shutters are linked to the company Motodori, later Tōkyō Seiki, which was certainly the owner of the "Convex" brand. In 1951, the Convex-Rapid was announced as "made by Tōkyō Seiki".[1]
