■ 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 light emitted by the flash is
obstructed by the lens hood, or by the lens barrel
depending upon the focal length or shooting
distance.
The built-in flash on the D100 has an angle of coverage
suited to focal lengths of 20mm and greater.
Vignetting occurs at a focal length of 18mm.
■ Using the lens hood
The lens hood blocks light rays that have harmful
effects on pictures. It also helps to protect the glass
surface of the lens.
Attaching the hood
• To facilitate attachment or removal of the hood, hold
it by the lens hood attachment index (
A) rather
than its outer edge.
• If the lens hood is not correctly attached, vignetting
may occur.
• The lens can be stored with the lens hood attached in
the reverse position.
