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 sur-
faces.
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.
• To protect the lens surface from dirt or damage,
the use of the L37C filter is recommended at all
times. The lens hood also helps to protect the lens.
• Keep the lens cap in place whenever the lens is not
in use.
• Attach both the front and rear caps when the lens
is stored separately.
• To ensure proper fit of the lens when stored in the
leather lens case, set the lens' focusing ring to the
infinity (°°) setting.
