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.

If you use ether in cleaning the lens, a smudge sometimes appears on the surface of a multi-coated lens. If this happens, wipe it again with a cotton cloth moistened with alcohol.

•Take care in cleaning the rear part of the lens with a spraygun-type blower because its strong stream of air may damage the lens diaphragm blades. To avoid damage, set the lens at full aperture and use the blower far enough away.

•Always protect the lens surface from dirt or damage. The lens hood also helps to protect the lens.

•Keep the lens cap in place whenever the lens is not in use.

•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.
