Lens Care
• Removing dust is normally sufficient to clean the glass surfaces
of the lens.
• Smudges and fingerprints can be removed from fluorine-
coated lens elements using a soft, clean cotton cloth or lens
cleaning tissue; clean from the center outwards using a circular
motion. To remove stubborn stains, wipe gently using a soft
cloth lightly dampened with a small amount of distilled water,
ethanol, or lens cleaner. Any drop-shaped marks left from this
process on the water- and oil-repellent surface can
subsequently be removed with a dry cloth.
• When cleaning lens elements that are not fluorine-coated,
remove smudges and fingerprints using a soft, clean cotton
cloth or lens cleaning tissue lightly dampened with a small
amount of ethanol or lens cleaner. Wipe gently from the center
outwards in a circular motion, taking care not to leave smears
or touch the lens with your fingers.
• Never use organic solvents such as paint thinner or benzene to
clean the lens.
• Neutral Color (NC) filters (available separately) and the like can
be used to protect the front lens element.
• 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.
