When shooting in low temperatures, the camera's lithium battery may fail due to prolonged exposure to cold environments, so it's crucial to maintain a comfortable camera body temperature. Therefore, extra care must be taken to keep the camera warm. Due to the low outdoor temperatures, keep the camera tucked inside your clothing and only take it out when needed. Otherwise, a sudden transition from a cold environment to a warm indoor environment may cause condensation on the lens and CMOS sensor. It is recommended that the camera not be exposed outdoors for more than half an hour continuously.

      Generally speaking, camera batteries usually have no problem shooting at -10 degrees Celsius; most medium-sized cameras are fine at -20 degrees Celsius; however, at -30 degrees Celsius, whether or not there are any problems depends entirely on luck. This is because lithium batteries deplete very quickly in low temperatures, retaining only about 70% of their capacity at room temperature. Therefore, it's essential to carry several spare lithium batteries when shooting outdoors, and remember to turn off the power when not shooting to conserve energy. Similarly, if you have an external battery compartment as a backup power source, you can place it inside your clothing and power the camera via a cable, or you can sew or buy a battery cover.
