Lens Care
• The lens returns to maximum aperture when removed from the
camera. To protect the interior of the lens, store it out of direct
sunlight or replace the lens caps.
• Do not pick up or hold the lens or camera using only the lens hood.
• Keep the CPU contacts clean.
• Should the rubber lens-mount gasket be damaged, cease use
immediately and take the lens to a Nikon-authorized service center
for repair.
• Use a blower to remove dust and lint from the lens surfaces.
• The fluorine-coated front and rear elements can be cleaned simply
by wiping them with a dry cloth. Smudges and fingerprints can be
removed using a soft, clean cotton cloth or lens cleaning tissue; clean
from the center outwards using a circular motion, taking care not to
leave smears or touch the glass surface with your fingers. To remove
stubborn stains, wipe gently using a soft cloth dampened with a
small amount of distilled water, ethanol, or lens cleaner. Drop-
shaped stains on the water- and oil-repellent fluorine-coated
elements can be removed with a dry cloth.
• Never use organic solvents such as paint thinner or benzene to clean
the lens.
• The lens hood or NC filters can be used to protect the front lens
element.
• Attach the front and rear caps before placing the lens in its flexible
pouch.
• If the lens will not be used for an extended period, store it in a cool,
dry location to prevent mold and rust. Do not store in direct sunlight
or with naphtha or camphor moth balls.
• Keep the lens dry. Rusting of the internal mechanism can cause
irreparable damage.
• Leaving the lens in extremely hot locations could damage or warp
parts made from reinforced plastic.
