High-Speed Sync (FP Flash)
When the flash mode is set to high-speed sync (FP flash), the flash can
synchronize with shutter speeds faster than the camera's fastest sync
speed. When high-speed sync is set, the <V
h
> icon lights in the viewfinder.
• High-speed sync can be used in the <p>, <Tv>, <Av>, and <M> modes.
• High-speed sync is effective when you want to:
(1) Blur the background for a daylight portrait.
(2) Create a catchlight in the subject's eyes.
(3) Soften harsh shadows on the subject's face.
