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 spray-gun 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 pro- tect the lens.

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