I have a few lenses with modern Copal shutters that work well except that the tension for the aperture control varies a lot. Some feel tight which I prefer. Others are loose and prone to drift with minor brushes of the hand.


Why the difference?
Is this something I can adjust myself?
What is the cure?


Thanks.
