Rear-curtain
sync
In shutter-priority auto or manual
exposure mode, flash fires just before the
shutter closes. Use to create effect of a
stream of light behind moving objects. In
programmed auto and aperture-priority auto, slow
rear-curtain sync is used to capture both subject and
background. Use of tripod is recommended to
prevent blurring caused by camera shake.

The flash does not fire.

The Built-in Flash
See page 425 for information on the lenses that can be used with the
built-in flash. Remove lens hoods to prevent shadows. The flash has a
minimum range of 0.6 m (2 ft) and can not be used in the macro range
of zoom lenses with a macro function.
i-TTL flash control is available at ISO sensitivities between 64 and
12800; at other sensitivities, the desired results may not be achieved at
some ranges or aperture values.
If the flash fires in continuous release modes (0 102), only one
photograph will be taken each time the shutter-release button is
pressed.
The shutter release may be briefly disabled to protect the flash after it
has been used for several consecutive shots. The flash can be used
again after a short pause.
