Maintenance Precautions

PERCAUTIONS

Avoid touching the lens surface. Remove the dust on the lens 
surface with a lens cloth or a blower. Keep the lens cap attached.

Using a circular motion with a lens tissue or cleaning cloth, gently 
remove oil, fingerprints, and grime from the lens surface, working 
from the center outward. 

If the lens is taken from a cold environment into a warm one, 
condensation may develop on the lens surface and internal parts. To 
prevent condensation in this case, please take measures to protect 
against moisture before moving the lens.
