What should I do if the camera lens is dirty?

1. First, remove the lens and cover the fuselage with the body cover. Remove the lens cap, UV mirror and hood one by one, and then use an air blower to blow away the dust on the mirror surface.

2. Use a lens pen to wipe the lens in a spiral direction from the center to the outside, and then blow it with an air blower.

3. Use a cleaning cloth to clean the UV lens as well. Use the same method to clean.

4. Finally, use dust-free cotton swabs to clean the metal bayonet and the metal contacts.
