There are a couple of things you do need to consider when it's cold out though. First of all, batteries don't like cold, so you may want to keep a second camera battery in an inside pocket, even a cold battery when it's brought into a warm place, can regain some power. If your camera and batteries are older, than you may want to replace the batteries with new ones. I always put the date on a battery when it enters service, as I can have several batteries that look the same, and not remember which one is the oldest.
Second of all, cameras don't like wet, cold air holds less moisture than warm air, a cold surface will chill the air immediately next to it, so don't open your camera bag until it has had time to warm up. This will keep moisture from condensing on the camera and lenses, it will condense on the outside of the bag instead. The best cold weather camera hat I ever had, was the old Konica TC, the mechanical parts didn't seem to mind the cold, and it worked fine using Sunny 16 type exposure, even with colour negative film. The FC-1 hated the cold, the 300D didn't seem to mind it, except when the batteries were old, they tended to go flat fairly quickly. LCD screens are okay to about -20℃ or about -4℉, although, you can keep a chemical hand warmer in your bag, and just take the camera out, make your shots, and back into the bag, or keep the camera inside clothing.
The image this time, is from the great ice storm of December 2013, when most of southern Ontario was covered in ice, which led to wide scale power outages, although the storm occurred on December 20th, it was New Years before the power was on everywhere. About a week before we moved, the new house had a total outage of maybe 10 minutes, the old one was out for over a week. This little twig got a coating of ice.
I hope to get another posting in, this month, will see you then. Not sure about December yet, December can be brutally busy, I will try to get in two, but may only get in one.
See you then, W.
