Flash Characteristics in Each
Exposure Mode
• When taking a moving subject, you can use the flash to change the blur
effect.
• Any desired shutter speed 1/180 sec. or slower can be set for taking a
flash photograph.
• The aperture value automatically changes according to the ambient
brightness.
• The shutter speed is locked at 1/180 sec. when lens other than DA,
DA L, D FA, FA J, FA, F or A is used.
• You can set the desired aperture to take a flash photograph when you
want to change the depth of field or shoot a subject farther away.
• The shutter speed automatically changes with the ambient brightness.
• The shutter speed shifts automatically anywhere from 1/180 sec. to a
slow shutter speed (p.58) that reduces camera shake. The slowest
shutter speed depends on the focal length of the lens in use.
• The shutter speed is locked at 1/180 sec. when lens other than DA,
DA L, D FA, FA J, FA or F is used.
You can use slow-speed-sync in . (Night Scene Portrait) or b (Shutter
Priority) mode when shooting portraits with the sunset in the background.
Both the portrait and the background are captured beautifully.

Using Slow-Speed-Sync
• Slow-speed-sync slows the shutter speed. Use the Shake Reduction function
or turn off the Shake Reduction function and use a tripod to avoid camera
shake. The picture will also blur if the subject moves.
• Slow-speed-sync shooting can also be performed with an external flash.
