DC-L10 About White spots appearing inside the lens

The lens has a coating treatment to reduce effects such as ghosting and flare. 
Due to this treatment, you may sometimes see white spots inside the lens (Image 1). 
These spots are caused by the coating and are not dust, so they do not affect photography at all.

Note: The appearance of the white spots can vary depending on the light source and the surrounding environment.
