Dust getting inside the camera can affect image quality. Here are some ways to deal with it:
Use an air blow: This is the most commonly used cleanup method. Use an air blower to aim at the lens to blow a powerful airflow that blows dust out. Be careful not to blow directly with your mouth, as your mouth may contain moisture and oil, which may cause damage to the lens.
Use a lens cleaning pen: The lens cleaning pen has a brush on one end and a toner sponge on the other, which can effectively clean dust and stains on the surface of the lens. When using, dust it off with a brush and then wipe the surface of the lens with a toner sponge.
Use damp cleaning paper or cleaning solution: This method is suitable for cleaning more serious stains. Dust is first swept away with an air blow or cleaning pen, and then the lens surface is wiped with a special lens cleaning solution and damp cleaning paper. Be careful not to drop the cleaning solution directly onto the lens, but on the cleaning paper.
If dust gets inside the camera, rather than just on the surface of the lens, more specialized equipment and techniques are needed to clean it up. Unless you have the appropriate expertise and skills, it is not recommended to turn on the camera yourself to clean it up, as this may damage the camera. In this case, it is recommended to send the camera to a professional repair service center for cleaning.
Regardless of the cleaning method, care needs to be taken to avoid scratches or other damage to the lens. At the same time, when using the camera, it is also necessary to avoid dust ingress as much as possible, such as using lens caps and avoiding changing lenses in dusty environments.
