Compur is a long-lived series of leaf shutters that were made by the German company F. Deckel, based in München (Munich), Germany. The Compur appeared in 1912[1] and was based on the Compound, but was equipped with a geared slow speed governor instead of a piston and cylinder device.
The first Compur shutters were dial set. This means that the speed setting is by way a rotating dial at the top of the shutter plate. The later models were rim set, with a speed setting rim around the shutter housing. Some Compur shutters were equipped with a self-timer beginning from 1928.[2]
The Compur-Rapid is a model released in 1935[3], attaining 1/500 in #00 size and 1/400 in #0 size.
After the war, the Synchro-Compur added a flash sync terminal using a the PC (Prontor-Compur) socket—the "German" style connector, which eventually became the global standard.
