7. 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.

•When the lens is not in use, attach the lens cap to protect the front lens element.

•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.
