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] Compur shutters have a set of speeds like T,B, 1, 1/2, 1/5, 1/10, 1/20, 1/50, 1/100, 1/250 with some having 1/300 instead of 1/250

The Compur-Rapid is a model released in 1935[3], attaining 1/500 in #00 size and 1/400 in #0 size. Some of the late model shutters had a flash terminal but this is for bulbs (M flash sync).

After the war, the Synchro-Compur added a flash sync swith for M or X and flash is connected using a the PC (Prontor-Compur) socket—the "German" style connector, which eventually became the global standard. At some point in the 1950s the speeds were changed to the modern set of speeds: B, 1, 1/2, 1/4, 1/8,1/15,1/30, 1/60, 1/125, 1/250, 1/500

Several variations of the Synchro-Compur can be found with suffxes such as Mx, MXV, with V indicating self time.

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