Lens Maintenance
• Removing dust is normally sufficient to clean the glass surfaces of the lens.
• When cleaning the fluorine-coated front lens element:
Smudges, fingerprints, and other oily stains can be removed using a soft,
clean cotton cloth or third-party 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 third-party lens cleaner.
Drop-shaped marks may form on fluorine-coated surfaces, which are highly
water- and oil-repellent. Such marks can be removed with a dry cloth.
• When cleaning the rear lens element, which is not fluorine-coated:
Smudges, fingerprints, and other oily stains can be removed using a soft,
clean cotton cloth or third-party lens cleaning tissue lightly dampened with a
small amount of ethanol or third-party lens cleaner; clean from the center
outwards in a circular motion. Be sure to clean evenly and thoroughly without
leaving smears.
• 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.
• Do not store the lens in direct sunlight or with naphtha or camphor moth balls.
If the lens will not be used for an extended period, store it in a cool, dry location
to prevent mold and rust.
