Had mine out on top of a mountain in Val D'Isare last week with temps of -36. Camera will be fine provided......
Leave it in the bag when you first go out so the sudden shif in temperature doesn't cause ctoomuch condensation on the len, likewise when you get back indoors.
Try and keep the batteries warm, keep them in an inside pocket till you need them, the cold eats battery power and you'll find they last a lot less time than usual.
Don't drop the camera in the snow !!
Otherwise you should be fine - Enjoy.
