Flash Sync Modes
The following fl ash sync settings are available in P, S, A, and M modes:
DescriptionFlash sync mode
This mode is recommended for most situations. In P and
A modes, shutter speed will au to mat i cal ly be set to values
between
1
/
60 and
1
/
500 s.
Red-eye reduction lamp lights for approximately 1 s before
main fl ash, causing pupils in subject’s eyes to contract and
reducing “red-eye” effect sometimes caused by fl ash. Ow-
ing to 1 s shutter-release delay, red-eye reduction is not
recommended with moving subjects or in other situations
in which quick shutter response is required. Do not move
camera while red-eye reduction lamp is lit.
In S and M modes, fl ash fi res just before shutter closes, creat-
ing effect of stream of light following moving subjects. In P
and A modes, slow-rear curtain sync is used to capture both
subject and background. Use of tripod is recommended to
prevent blurring caused by camera shake.
Rear-curtain sync
Slow rear-curtain sync
Combines red-eye reduction with slow sync. Available only
in P and A modes. Use of tripod is recommended to prevent
blur ring caused by camera shake.
Slow sync with red-
eye reduction
Flash is combined with shutter speeds as slow as 30 s to
cap ture both subject and background at night or under dim
light. Available only in P and A modes. Use of tripod is rec-
ommended to prevent blur ring caused by camera shake.
Slow sync
Red-eye reduction
Front-curtain sync
Flash Angle
The fl ash angle of the built-in Speedlight can cover the fi eld of view of a 20 mm lens. It
may not be able to light the entire subject with some lenses or apertures ( 101).
ISO Auto
When On is selected for Custom Setting 5 (ISO auto; 142), sensitivity will automati-
cally be adjusted as required for optimal fl ash output. If a high sensitivity is required,
this may result in the background being overexposed when the fl ash is used at slow
shutter speeds (slow sync), in bright daylight (daylight sync), or when the background
is brightly lit.
