Likely the biggest issue you'll face during shooting is battery drain, which is fast at low temps. Keep a spare or two in a pocket inside your coat (where your body heat will keep it warm).


When you come back inside, the manual is correct - the idea is to prevent condensation inside the camera, which will occur when you bring the cold camera into the warm (and more humid) indoor environment. You want the camera itself to eitherwarm up unexposed to the humid air, or towarm up slowly,. For the former, put it in a heavy-duty ziploc bag (that was also out in the cold), squeeze out as much air (outside) as you can, then bring it in - in that case, the condensation will form on the outside of the ziploc bag. For the latter, keep your camera in your camera bag, assuming that was also outside in the cold, and when you bring it in, leave it in there for a few hours (this method really does both, since there's not a lot of air movement into the closed bag). One additional approach to the gradual warm up is to first bring the camera bag into an indoor but unheated space (garage, basement), then later bring it into the heated part of the house.
