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.
