    Changing shutter speed when cocked

    Title says it all really! Can you change the shutter speed after you have cocked the shutter - I'm sure you can, but I just wanted to confirm that changing the shutter doesn't cause any damage.

    Cheers

    I think it depends on the shutter.

    It should not cause any damage, it would cause a little extra friction, but yes you can !
    At least with Copal and Compur shutters.

    it is not a problem with modern Copal and Compur shutters. I've not had any problems with this with the Wollensak Rapax (a.k.a Graphex) shutters either.

    It's a modern Copal shutter.

    Older rimset Compur's can't be moved to or from the highest speeds if the shutter is cocked, forcing them will damage the shutter.

    While it is not a LF camera, Hasselblad V cameras have lens shutters and Hasselblad recommends advancing the film [which cocks the shutter] before storing. Obviously, if the shutter is stored cocked, then the shuttle speed can be changed after cocking.

    I hope this helps.

    Warning!! Handling a Hasselblad can be harmful to your financial well being!

    I know the question has been answered but for the record (and anyone contemplating a Zorki-4,) the shutter needs to be cocked first on a Zorki.
