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.

During WWII the Japanese shutter maker Bikōdō probably made Compur variants named Tokyo Compur and Rapid Compur for the Rollekonter TLR cameras.
