Quoting "Koch, Gerald" <gkoch02@xxxxxxxxxx>: > It > is extremely important not to leave a shutter cocked for long periods of > time. The manufacturers of the older leaf shutters generally recommend the shutter be left cocked. From a mechanical point of view, the cocked state will result in less chance of the shutter misbehaving (going sticky) as the driving spring is much stronger than the return spring, so there is more force available to 'break free' any sticky parts.
