The Copal Press shutters, available in the #0 and #1 size, are high performance, durable self-cocking shutters designed for professional photographers. Their shutter release lever exposes film or digital sensors as fast as you can reload a holder or download an image.
Originally designed for press photographers who neededed to shoot quickly, they feature two unique advantages versus the conventional "cock and release" Copal shutters supplied with large format lenses: they are always cocked (because the act of firing the shutter readies the springs for another exposure), and the shutter can be quickly opened to its maximum aperture via a lever or a cable release (there are two cable relase sockets on Copal Press shutters).
The click-stop lever controls shutter speeds from 1 second to 1/125th second, plus "Bulb". The flash sync terminal is the standard "PC" type.
Note! f/stops are not calibrated, and their positioning depends on the lens that is to be coupled with the shutter.
