Good morning fellows!

I have recently purchased a Widelux F8 and I immediately noticed the weird shutter release button assembly, with that sort of crown that can be unscrewed. I wonder how one could adapt a standard cable realease. Does it have the same thread as old Leica/Canon cable releases perhaps?

While we're on the matter, I experienced much resistance rewinding the film with the small knob on the left. It's extremely hard. Not so hard you can't do it, but hard enough to wonder if you could break something by twisting the tiny knob with that momentum. Is this "normal"? Or does some clutch/friction device need some maintenance?

Thanks for reading - M.
