The Prontor is a long-lived series of leaf shutters made by the German company Gauthier based in Calmbach.
The Prontor II exists with the following speed ranges:
- T, B, 175, 100, 50, 25, 10, 5, 2, 1, not synchronized
- 200, 100, 50, 25, 10, 5, 2, 1, B, T, synchronized
The Prontor-S is synchronized.
The Prontor-SV has dual M/X synchronization and exists with 1, 2, 5, 10, 25, 50, 100, 250, B speed range.
The Prontor-SVS has a common mechanism for the M/X synchronization and the self-timer.

The Prontor-Press is a so-called "press shutter". That means that it is a self-cocking flash synchronized large format leaf shutter. It has five shutter leaves and an additional five-leaves aperture. Its speed range is 1 sec. to 1/125 sec. and includes T and B mode. Speeds can easily be set stepwise by means of the setting ring around its front. It has a screw mount in either the front and the back since it's a shutter for lens kits with separate barrels for front and rear elements. The shutter's release lever can alternately be operated with a common remote cable.
