Copal Press 0 vs. Copal 0

[Glenn Kroeger]

I have been using Copal 0 and 1 shutters for many decades, but I have a chance to buy a recently manufactured Rodenstock lens that is in a Copal Press 0 shutter. I am in for any mean surprises? Any significant difference in accuracy or reliability?

Top speed 1/125, otherwise no significant differences. And, of course, self-cocking, so handy for multiple pops.

Cheers,

Dan

I to have been curious about this as i just had a 240mm G-Claron mounted in a copal press#1 and was wondering if there were any drawbacks. Top speed on mine is 1/150th which considering most exposures,if not all, will be much longer than that isn't a drawback. I did wonder if anyone has ever experienced increased vibration problems though considering the power and long stroke of the cable release to cock and fire one of these beasts.

Personally, I prefer self-cocking shutters for cameras which will never be hand-held. I don't think vibration is much of a problem, but shake may be. You can reduce the possibility by using a rubber bulb with a deGroff piston.
