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) 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) or c (Aperture
Priority) 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.
