Rectus
Rectus is the name of a shutter found on some Japanese cameras from the 1950s. There are at least two variants, with B, 1–200 and B, 1–300 speeds. According to a post in the Classic Camera Repair Forum it was a copy of the Prontor II. According to this page at Japan Family Camera, it was made by a company called Fuji Seimitsu (富士精密), together with a shutter called Ceres. The maker of the Ceres is confirmed by an advertisement dated September 1955.[1] (Today there is a company called Fuji Seimitsu, but its website says that it was founded in 1962.)
The following lists are incomplete. That a particular model is listed should not be taken to mean that all examples were fitted with the particular model of shutter.
