What should I pay attention to in the usual maintenance of digital cameras?

Keeping the camera clean is the most important thing.

Common tools are simple: lens paper or fine tools with fiber cloth, lens brush, cleaning suit.

When the lens paper is not used, put the microfiber cleaning cloth in the original container to keep it clean. Microfiber fabrics are very washable. Try not to use cotton T-shirts or other fibers, because coarse gravel may seep in. If you use a brush to clean the dust and debris on the lens, do not touch the hair on the brush with your hands or fingers. The oil on your skin will infect your hair and then stick to the lens.

Another way to clean the dust on the lens is to blow the lens with air frequently. Fingerprints or stains can also be erased with a lens pen.

Hot and cold weather can also affect the camera. If the camera was originally placed in an air-conditioned room and then immediately placed in a hot and humid environment, fog spots would appear on the lens and viewfinder. At this time, it is necessary to clean it with a suitable paper towel or cloth. If you bring the camera into the room from the cold and dry outdoor, you'd better put it in your bag to preheat it, and then take it out and put it in the house. And carefully hold the camera to see if it is "sweating". If you are sweating, you should take action at once. Professional photographer's advice: take a plastic zipper lock bag with you. In very humid or dusty climate, you can dig a small hole in the side to install the camera lens and put the camera in a bag to prevent fog, moisture and dust from entering the camera, which can prolong its service life.

Finally, don't put the camera in the back seat of a hot car. The car is like a stove, which will deform the plastic and damage the wires.

Many manufacturers will suggest that if you don't use the camera for more than two weeks, you'd better take it out, because the battery will leak and rot, sometimes affecting the circuit connection, making the camera unable to work normally.
