just keep it on an inside pocket or use silica gel. whenever I film i put my camera in a bag and under my coat right before i take my skis off, then go inside, let it slowly warm up (like a few min) then take it out. used silica gel if you are really worried, but i've never had problems. also i go all the time with an ipod, and same thing, just keep it on an inside pocket, its the drastic and quick change in temp that causes condensation
