How and when should I clean the lens?

• Clean the lens whenever you notice dirt or dust on the surface.
  • To remove dirt or smears on the lens, use lens-cleaning paper. If necessary, moisten a soft, lint-free cloth with lens cleaner and gently wipe the lens surface.
  Caution: Do not use glass cleaner to clean the lens or rub the lens with abrasive materials. Avoid touching the lens with your bare hands to prevent fingerprints or damage to the lens surface.
