Using the Built-in Flash
When taking a moving subject, you can use the flash to change the blur
effect.
The aperture value automatically changes according to the ambient
brightness.
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.
You can use Slow-speed Sync in . (Night Scene Portrait) of H (Scene)
mode or b (Shutter Priority Automatic Exposure) mode when shooting
portraits with the sunset in the background. Both the portrait and the
background are captured beautifully. G and H can be used in e
(Program Automatic Exposure) or c (Aperture Priority Automatic
Exposure) mode.

Using the Slow-speed Sync
Slow-speed Sync slows down 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 can also be performed with an external flash.
