camera/asthma

[pattonxl]

I am off to the antarctic pennisula in march and i was wondering my slr camera will hold up with the temperature. I work in a freezer warehouse most of the days, and the scanners have to be replaced every hour or so as they frezze up.
Also anyone have any difficulty breathing? I have asthma, and the docs don't know how it will effect me being in the cold for extended periods of time.

thanks
