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.
