■The built-in flash and vignetting
• T he built-in flash cannot be used over distances of
less than 0.6 m (2.0 ft.).
• To pr event 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 focal length or shooting distance.
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

Attaching the hood

Align the lens hood attachment index (A, either of
two indexes) 2 on the hood with the lens hood
mounting index 4 on the lens, and turn the hood
counterclockwise (as viewed when holding the camera
with the lens facing away from you) until it clicks into
place (Fig. B).
• Be sure that the lens hood mounting index is aligned
with the lens hood setting index (B) 3.
• If the len s hood is not correctly attached, vignetting
may occur.
• To facilitate attachment or removal of the hood, hold
it by the base (near the lens hood attachment index)
rather than its outer edge.
• T o store the lens hood, attach it in the reverse
position.

Detaching the hood

Hold the lens hood by the base (near the lens hood
attachment index) and turn clockwise, as viewed when
holding the camera with the lens facing away from you,
to detach.
