Maintenance Precautions
PERCAUTIONS
Avoid touching the lens surface and apply lens cloth or air blow to
remove dust from it, you can also install UV lens for protection
purpose. Close the lens cap when it is not in use.
Gently remove any dirt and fingerprints by rubbing the lens surface
in spiral motions (from center to the periphery) with lens tissue or
cleaning cloth.
When the lens is taken from a cold environment into a warm one,
condensation may develop on the surface and internal parts of the
lens, so moisture protection should be taken when transferring.
