Variable maximum apertures
Zooming the lens changes the maximum aperture by
up to 11/3 stop.
However, the camera will compensate for any change
in aperture by adjusting the shutter speed so as to
maintain the correct exposure value.
The built-in flash and vignetting
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 1, or lens barrel,
depending on the focal length or shooting distance.
• To prevent vignetting, do not use the lens hood 1.
• The built-in flash cannot be used over distances of
less than 0.6 m (2.0 ft.).
The built-in flash on the D100 and D70 is compatible
with focal lengths of 20mm or greater.
Vignetting occurs at a focal length of 18mm.
Lens care
• Be careful not to allow the CPU contac ts 0 to
become dirty or damaged.
• 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.
• NC filters are available to protect the front lens
element. The lens hood 1 also helps to protect the
front of the lens.
• When s toring the lens in its flexible lens pouch, attach
both the front and rear lens caps. The lens can also be
stored with the lens hood 1 attached in the reverse
position.
• When the lens is mounted on a camera, do not pick
up or hold the camera and lens by the lens hood 1.
• When the lens will not be used for a n 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 plast ic is used for certain parts of the lens.
To avoid damage, never leave the lens in an
excessively hot place.
