Seikosha Rapid on Mamiya SIX IV image by Dirk HR Spennemann (Image rights) |
The Seikosha-Rapid is a Japanese leaf shutter, inspired by the German Compur-Rapid and made by Seikōsha, the manufacturing branch of Hattori Tokei-ten.
Some sources say that the Seikosha-Rapid was developed in 1941 and sold from 1946 in #00 size, with 1/500 top speed.[1]
However the oldest occurrence of the Seikosha-Rapid found so far is an advertisement for the First Reflex placed in a book dated February 1940.[2] It is not sure if the camera was actually sold with that shutter. The Minion III is mentioned with a "Rapid Seiko" shutter in the "Kokusan shashinki no genjōchōsa" ("Inquiry into Japanese cameras") of early 1943, and it was perhaps already available at the time.[3]
The Seikosha-Rapid was also developed in #0 size in 1952 with 1/400 top speed.[4] The Seikosha-Rapid was followed by the Seikosha-MX.
