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 flash 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 125 is a self-cocking shutter, named after its maximum speed 1/125 sec. .
The Prontor 300 is also named after its max. speed, but needs cocking.
The Prontor 300 LK, Prontor 500 LK and Prontor 1000 LK are meter-coupled Prontors.
The Prontor-SLK is a fast flash synchronized meter-coupled shutter.
The Prontor-Mat-S was a shutter for early cameras with automatic exposure setting control.
Prontor-Press with JML lens |
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-leaf aperture iris. Its speed range is 1 sec. to 1/125 sec. and includes T and B modes. Speeds can easily be set stepwise by means of the speed 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.
The Prontor Press Electronic is an electronically controlled shutter, the Prontor magnetic another electrically-driven one.
The Prontor Professional is a large format shutter with speeds from 1 to 1/125 sec. plus B. It has an additional cable release thread for an aperture release, a lever to switch from stepless to stepwise aperture setting, and facilities to connect its aperture levers to a mechanical aperture remote control on the camera back.
