12pm What should I do if there is always dust around the camera?

Blow with a blower.

The correct method should be to first use a blower (also called an ear cleaning ball) to blow off the dust on the surface of the lens. This kind of blower is sold in general photography stores, and the price ranges from a few yuan to a few dollars. The price ranges from ten yuan, but be careful not to use self-service compressed air tanks as the pressure may be too high, which may blow dust into the gaps in the lens. Do not blow directly with your mouth, otherwise there will be a lot of saliva particles. to the surface of the lens, which would be more difficult to deal with. Use an ear blower to blow off the fine dust on the lens.
