Flash photography using cameras with
a built-in flash
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 contacts 8 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 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 1 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. 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 an extended period of
time, store it in a cool, dry place to prevent mold. 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.
