Can I use a camera in winter in Northeast China?

Hello, my friend, please allow me to answer seriously: First of all, I am from Heilongjiang, and I know the winter in Northeast China very well. But I'm not a professional photographer. My hobby is photography. My Canon 7D camera also has a high-definition camera function, which is certainly not as good as a professional camera. But I shot the world of ice and snow in Harbin on a winter night, and it took me more than three hours to use the camera. There is no protection, and there is nothing wrong with the camera. I'm freezing anyway. I also know some people who work in TV stations. It is said that their cameras have no special protection when shooting outdoors in winter, but it seems that few people work outdoors for more than five hours in a row. As far as I know, general professional photographic equipment has certain low temperature resistance. Low temperature will have no effect on the equipment, and the LCD screen may have the greatest impact. The LCD screen will have reaction delay and partial condensation at low temperature, but it will recover quickly after returning to normal temperature without causing permanent damage. Generally, we should pay attention to two points: the first is the battery problem mentioned by a "carefree" friend. Low temperature will greatly reduce the activity of lithium-ion batteries, that is, power, which will generally be reduced to less than half of normal temperature. Therefore, when working outdoors in low temperature, you must prepare more spare batteries and keep them warm in a warm place when not in use, such as clothes near your pocket or in your car. The second "carefree" also said that what digital products are most afraid of is not low temperature, but condensation caused by water vapor at low temperature, which will seriously affect the reliability of electronic equipment. The correct way is not to use the camera from low temperature to high temperature immediately, but to seal it with airtight plastic bag or put it in a camera bag with moisture-proof equipment, and then take it out when the temperature of the equipment is close to the ambient temperature. In a word, the low temperature has little effect on the short-term use of professional equipment (within a few hours) and does not need special protection. Instead, we should pay attention to the influence of low temperature on battery capacity, especially moisture-proof, and must not be careless. Please continue the discussion if you have any questions. If it helps you, please accept it as a satisfactory answer. Despise people who maliciously evaluate other people's answers!
