Hi guys, I've got a question. My pal will be travelling to Europe and I'll be lending him my gears. I haven't got any experience using a camera in European countries where there's difference in weather compared to here. So, I'd like to ask for some tips on taking care of the camera, i.e. to avoid water vapour and stuffs (I mean, do they even need to since everywhere is cold over there?). My friend is not a camera person and he'll be there for about 2-3 weeks.
