Seikosha (shutter)
The Seikosha is a Japanese leaf shutter in #0 size. It was developed in 1932 by the Japanese Seikosha company, inspired by the German Compur.[1] It is sometimes called "Seikosha S", apparently because it is equipped with a self-timer and by analogy with the Compur-S. In an advertisement for the Lord by Tōkyō Kōgaku[2] it is called S Seiko (Sセイコー).
Variants and cameras equipped (incomplete list, and not all variants are concerned):
- T, B, 1, 2, 5, 10, 25, 50, 100, 250
- Lord (Tōkyō Kōgaku) by Tōkyō Kōgaku (some sources call it "Seikosha S")
