Hi Mark, Since I don't have a Mz-S, I am just brainstorming. Batteries would surely lose power after 45 minutes in those temperatures. I would guess that could really slow the shutter down a lot. That would account for the overexposure you experienced. I know it did on my old cloth focal-plane shutters in the Colorado mountains. I would keep an extra set of batteries in an inside pocket and switch them out often if I were you. But then again, what do I know about that kind of cold. We cry when it gets down into the 20s here. ;-) Ken
