Using the Built-in Flash
If the flash is fired multiple times in quick succession, the flash and
shutter may be temporarily disabled to protect the flash. Shooting can
be resumed after a brief pause.
Objects close to the camera may be overexposed in photographs taken
with the flash at high ISO sensitivities.
To avoid vignetting, remove lens hoods and shoot at ranges of at least
0.6 m (2 ft). Some lenses may cause vignetting at greater distances or
obstruct the red-eye reduction lamp, interfering with red-eye reduc-
tion. The following illustrations show the effect of vignetting caused by
shadows cast by the lens when the built-in flash is used.
