Do I need to bring a drying oven when I go out with a SLR?

No, we usually take out the sealed bags. The sealed bag is filled with desiccant.

Sealed bags are sealed plastic bags, which are sold in supermarkets.

Although the humidity in the north is low, due to the large temperature difference between indoor and outdoor, the camera is prone to fog or even condensation, so it is generally necessary to put the camera in a sealed bag with desiccant before entering and leaving the house.

In addition, there will be more dust outdoors in the north, so it is more convenient to change the lens outdoors with a larger drying bag (the lens and camera are changed in sealed bags).

When taking pictures in cold places, be sure to take a spare battery, because when it drops below 0℃, only about 50% of the battery is available. As for Harbin, it is estimated that the situation is even less optimistic. The landlord can buy a 450-purpose handle, or buy more batteries (just like the one with the best product).
