■ Setting the aperture
Use the camera to adjust the aperture setting.
■ The built-in flash and vignetting
• The built-in flash cannot be used over distances of
less than 0.6 m (2.0 ft.).
• To prevent vignetting, do not use the lens hood.
* Vignetting is the darkening of the corners around the
image that occurs when the light emitted by the flash
is obstructed by the lens hood, or lens barrel,
depending on the shooting distance.
■ Lens care
• Be careful not to allow the CPU contacts 8 to
become dirty or damaged.
• If the lens mount rubber gasket 7 is damaged, be
sure to visit the nearest Nikon-authorized service
representative for repair.
• Clean lens surfaces with a blower brush. To remove
dirt and smudges, use a soft, clean cotton cloth or
lens tissue moistened with ethanol (alcohol) or lens
cleaner. Wipe in a circular motion from the center to
the outer edge, taking care not to leave traces or
touch other parts of the lens.
• Never use organic solvent such as thinner or benzene
to clean the lens, as this could cause damage, result in
a fire, or cause health problems.
• NC filters are available to protect the front lens
element. The lens hood also helps to protect the front
of the lens.
• When storing the lens in its flexible lens pouch, attach
both the front and rear lens caps.
• When the lens is mounted on a camera, do not pick
up or hold the camera and lens by the lens hood.
• When the lens will not be used for an extended
period of time, store it in a cool, dry place to prevent
mold and rust. Be sure to store the lens away from
direct sunlight or chemicals such as camphor or
naphthalene.
• Do not get water on the lens or drop it in water as this
will cause it to rust and malfunction.
• Reinforced plastic is used for certain parts of the lens.
To avoid damage, never leave the lens in an
excessively hot place.
