I typically don't have problems. I just make sure not to bring a cold camera into a warm, humid environment. If I can't help doing that, I let the camera come up to room temperature before using it again. Most of the time, I'm just getting back into a cold car, so it's not really an issue.
Also, I make sure to have at least one if not two backup batteries in my coat, next to my body.

That's some pretty severe weather for electronics, do or did you ever have any problems with the camera shutting down, battery drain, lens frosting etc. Just wondering in case I ever get to see snow or ice, and what do you do to prevent equipment failure?
