D Lens Care • When a lens hood is attached, do not pick up or hold the lens or camera using only the 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. To remove smudges and fingerprints, apply a small amount of ethanol or lens cleaner to a soft, clean cotton cloth or lens-cleaning tissue and clean from the center outwards using a circular motion, taking care not to leave smears or touch the glass with your fingers. • 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.
