[Largeformat] Re: Compur and Copal shutter

["Tigershark " <tigershark_001@hotmail.com>]

Also, just for peace of mind, Copal (shutters and large 
commercial lab-size automatic color photo printers), Seiko (watches), 
and Epson are all the same company.

I have several lf lenses Schneider and Nikon (yes Nikon), all modern 
glass and indeed have Copal shutters.  No problems with them so far.  

There is a 3rd kind of shutter, the Prontor, which has models with 
self-cocking shutter mechanisms and some way to set aperture and 
shutterspeed from BEHIND the camera.  I never needed those or looked 
into them, but they are around.
