LENS CARE
• Clean lens surface 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 and not to touch the other lens parts.
• Never use thinner or benzine to clean the lens.
• To protect the lens surface from dirt or damage, use of an NC filter is
recommended at all times. The lens hood also helps protect the lens.
• Cover lens with lens cap when lens is not in use.
• Attach both front and rear caps when the lens is stored separately.
• If you will not use the lens for a long time, protect it from rust and mold by
storing it in a cool, dry place. Also, do not store in direct sunlight, and keep it
away from naphthalene or camphor.
• Be careful not to get the lens wet or drop it in water. Water on the lens may
cause malfunction.
• Reinforced plastic is used on the exterior of the lens unit; to avoid damage,
take extra care to never leave the lens in an excessively hot place.
