Yes, as far as I know, condensation is going to be your only true enemy. It forms when going from cold to hot. I have found that it’s usually good enough to just make sure all my equipment is in the camera bag before taking it into the house or car (vs putting it into plastic bags like I have in the past). I try to keep it in the bag for at least an hour.
It’s kinda amazing that cameras function so well in the cold! The only problem I’ve experienced with cold was when I was biking with the camera around my neck. It couldn’t have been colder than 10 degrees F. The windchill evidently was enough to make the LCD screens work very slowly and eventually not work at all. I was a little scared at first, but it revived no problem after it got warmed up later.
