I\'ve spent some time in extended cold, equipment always suffers in one way or another. If you expect to be in temps between 0 (F) and +32 (F) you should really be quite come once you acclimate. My batteries worked better than any I have used in the past. I use the D3s and they lasted 2+ days being exposed 8 to 10 hrs a day. BTW temps were 0 to -25 F. My zoom lens ring rotated very slow after a few hours, many times I just shot at what it was as I didn\'t want to damage anything.
Primes had no problem. You need some way to control potential moisture however if you are staying below 32 F 95% of the time it may not be an issue. I use larger resealable bags from a company called Uline. They come in various sizes. Several days I would levee the lens & body outside over night, remove the battery & cards, I take enough cards so I do not need to download until I am in reasonable temps.
I\'d test my equipment on your next trip, my main concern was camera batteries, I took 3 for each body on my last trip and never had an issue there. If possible next month you should be able to get a good idea of how your batteries hold up.
It goes without saying if you get your equipment wet outside while in the conditions you describe it\'s going to freeze up. You can PM me if you have any further questions I might be able to help you with.
Cheers
