Flash Sync Modes
The camera supports the following fl ash sync modes:
Flash sync mode Description
Front-curtain sync
Recommended for most situations. In programmed auto and ap-
erture-priority auto modes, shutter speed will au to mat i cal ly be set
to values between / and / s (/ to /, s when using optional
Speedlight with Auto FP High-Speed Sync;
160).
Red-eye reduction
Red-eye reduction pre-fl ash lights for approximately one second
before main fl ash. Pupils in subject’s eyes to contract, reducing
“red-eye” eff ect sometimes caused by fl ash.
Red-eye reduction
with slow sync
Combines red-eye reduction with slow sync. This mode is only
available in programmed auto and aperture-priority auto ex po -
sure modes. Use of a tripod is recommended to prevent blur ring
caused by camera shake.
Slow sync
Flash is combined with speeds as slow as 30 s to cap ture both
subject and background at night or under dim light. This mode
is only available in programmed auto and aperture-priority auto
ex po sure modes. Use of tripod is recommended to prevent blur-
ring caused by camera shake.
Rear-curtain sync
In shutter-priority auto or manual exposure mode, fl ash fi res just
before the shutter closes, creating eff ect of a stream of light be-
hind moving objects. In programmed auto and ap er ture-pri or i ty
auto, slow rear-curtain sync is used to capture both sub ject and
background. Use of tripod is rec om mend ed to pre vent blurring
caused by camera shake.
Red-Eye Reduction
Some lenses may block the red-eye reduction lamp, preventing the subject from seeing
the lamp and interfering with red-eye reduction.
Studio Flash Systems
Rear-curtain sync can not be used with studio fl ash systems, as the correct syn chro ni za tion
can not be obtained.
Compatible Lenses
See the Appendix for information on the lenses that can be used with the built-in fl ash.
e3—Built-in Flash ( 161)
Flash mode can be selected from TTL, Manual, Repeating Flash, and Commander
mode. When fi red at full power in Manual mode, the built-in fl ash has a Guide Number
of 13/42 (ISO 100, m/ft). In Repeating Flash mode, the fl ash fi res repeatedly while the
shutter is open. The fl ash output, number of fl ashes, and interval between fl ashes can
be selected from a menu. Commander mode can be used for wireless off -camera fl ash
photography with optional SB-800, SB-600, or SB-R200 Speedlights.
