8. Lens care
•Clean the lens surfaces with a blower brush. To remove dirt and
smudges, use a soft, clean cotton cloth or lens tissue moistened with
ethanol (alcohol) or lens cleaner. Wipe in a circular motion from center
to outer edge, taking care not to leave traces or touch other parts of
the lens.
•Never use thinner or benzene to clean the lens as this might damage
it, result in a fire, or cause health problems.
• To protect the front lens element, an NC filter is recommended at all
times. A lens hood also helps protect the front of the lens.
•When storing the lens in its lens case, attach both front and rear caps.
•When the lens will not be used for a long time, store it in a cool, dry
place to prevent mold. Also store the lens away from direct sunlight or
chemicals such as camphor or naphthalene.
•Do not get water on the lens or drop it in water as this will cause it to
rust and malfunction.
•Reinforced plastic is used for certain parts of the lens. To avoid
damage, never leave the lens in an excessively hot place.
