LENS CARE
• Although you should always keep the lens surfaces clean, rough cleaning must be avoided. Wipe with a
soft, clean cotton cloth moistened with alcohol to remove grease or fingerprints from the lens surfaces.
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 do not intend to 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.
