Exposure Mode
When taking a moving subject, you can use the flash to change the blur
effect.
Any desired shutter speed of 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 a lens other than a DA,
DA L, D FA, FA J, FA, F or A lens is used.
You can set the desired aperture value 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.68) 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 a lens other than a DA,
DA L, D FA, FA J, FA or F lens is used.
You can use Slow-speed Sync in . (Night Scene Portrait) of Picture
mode or b (Shutter Priority) mode when shooting portraits with the sunset
in the background. Both the portrait and the background are captured
beautifully.

Using the 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.
