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.
