Hi I have posted a similar question a few days ago on the Medium FOrmat Forum, with no success so here I am giving a try here in this probably more appropriate forum. I have unwillingly left my P67ii with the shutter open and the mirror raised for about 3 hours, in the time exposure mode, with the main switch set to off. I wonder if this unusual long exposure might have caused damage on any part of the body (like springs, shutter curtain etc).

Thanks in advance
