Safe flash use
When lighting is poor and the flash is set to “Off” ( ) or “Slow Sync”
(
), shutter speed slows and photos may be blurred. If possible, use a
tripod when lighting is poor. At speeds of below
1
/
4
s, the shutter speed
indicator in the LCD monitor turns yellow. Noise may appear in photo-
graphs taken at speeds slower than this value.
The built-in flash will automatically be set to “Off ” ( ) when:
• you use autofocus with a setting of “Infinity” ( )
• you choose a multi-shot setting of Continuous, Multi-shot 16, VGA
Sequence, or Ultra HS (an external flash can still be used with these
settings)
• you choose a multi-shot setting of Movie
• you use best-shot selection (BSS)
• you use lens converter (LENS) settings
• the AE Lock option in the EXPOSURE OPTIONS sub-menu is on
When using the flash, be sure the flash window is unobstructed.

A short pause is required between exposures for the flash system to charge.
While the flash is charging, the red flash lamp next to the viewfinder will
blink when the shutter-release button is pressed halfway. Try again after
briefly removing your finger from the shutter-release button.
