: Use this mode for automatic flash photography. The flash sync speed
and flash aperture will be set automatically as with the <D> (Full Auto)
mode.
Use this mode if you want to set a flash sync speed slower than 1/90
sec. The camera will set the flash aperture automatically to obtain a
correct flash exposure.
Use this mode if you want to set the flash aperture. In this mode, you
can obtain a balanced exposure between the subject and a dark
background (night scene, etc.) with a slow sync speed set automatically
by the camera. The flash illuminates the subject while the background is
exposed with a long shutter speed.
This mode enables you to set both the flash sync speed and flash
aperture. The subject is properly exposed with the flash and the
background is exposed with the flash sync speed and aperture you have
set.
The result will be the same as using the <P> mode.
