Urgent! ! ! Excuse me, photographers, can Fuji digital camera F85 work normally at minus five degrees?

Of course. There are some precautions:

When you go out, you should put your camera in your bag before going out. There is a surplus.

When you go back, you should put the camera in your bag, zip it up and go back. Also note that don't take out the camera right away. It's better to wait for three to five hours, and then take it out when the temperature of the camera and the room are not much different. Especially in the north, there is warm steam indoors, and the air temperature is high, so it is easy for water vapor to enter the camera, which affects the service life of the camera. It doesn't matter if your camera is old. Just in time to buy a new one. Pay special attention to a good camera.
