Nikon AI-S AF DC-NIKKOR 135mm f-2 - Manual (Page 15)

LENS CARE
• Although you should always keep lens surfaces clean, rough cleaning must be
avoided. To remove grease or fingerprints from the lens surfaces, wipe with a soft,
clean cotton cloth moistened with alcohol.
• Never use thinner or benzine to clean the lens.
• To protect the lens surface from dirt or damage, use of an L37C filter is recom­
mended at all times. The lens hood also helps protect the lens.
• Cover lens with lens cap when lens is not in use.
• Attach both front and rear caps when the lens is stored separately.
• If you will not use the lens for a long time, store it in a cool, dry place away from
direct sunlight.
• Reinforced plastic is used for some parts in the lens unit; to avoid damage, take
extra care to never leave the lens in an excessively hot place.
