To obtain a correct flash exposure, the flash output will be set automatically
(autoflash exposure) to match the manually-set aperture. The shutter speed
will be set automatically between 1/250 sec. - 30 sec. to suit the scene's
brightness.
In low light, the main subject is exposed with the automatic flash, and the
background is exposed with a slow shutter speed set automatically. Both the
subject and background look properly exposed (automatic slow-speed flash
sync). If you are handholding the camera, keep it steady to prevent camera
