Flash Modes
The flash modes listed on the previous page may combine one or more of the following
settings, as shown by the flash mode icon:
•
AUTO (auto flash)
: When lighting is poor or subject is back lit, flash pops up automatically
when shutter-release button is pressed halfway and fires as required.
• j
(red-eye reduction)
: Use for portraits. Red-eye reduction lamp lights before flash fires,
reducing “red-eye.”
• j (off) : Flash does not fire even when lighting is poor or subject is back-lit.
•
SLOW (slow sync)
: Shutter speed slows automatically to capture background lighting at night
or under low light. Use to include background lighting in portraits.
•
REAR (rear-curtain sync)
: Flash fires just before shutter closes, creating a stream of light behind
moving light sources (below at right). If this icon is not displayed, flash will fire as the
shutter opens (front-curtain sync; the effect this produces with moving light sources is
shown below at left).

The Built-in Flash
For information on the lenses that can be used with the built-in flash, see page 200. 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.
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.
