View Full Version : Copal 1 shutter has only one shutter speed

22-Jan-2016, 11:58
I purchased a lens with Copal 1 shutter recently, the T and B work well. The shutter speeds from 1S to 1/400S are similar and are around 1/100-1/150S. I managed to open the front of the shutter, but could not determine what had been wrong (there must be something wrong:)). Does anybody know the reason/answer and could you please point the shutter problems to me? Thanks!
