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.
• To protect the lens surface from dirt or damage, the use of an L37C filter is recom-
mended 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.
