Instruction Manual

1. High-Speed Sync (FP Flash)

When you set the synchronization mode to high-speed sync (FP flash), the

camera can synchronize with the 550EX at all shutter speeds. When high

speed sync has been set, iiH is displayed in the viewfinder.

• High-speed sync can be used in the E-TTL and M Hash modes.

• High-speed sync is especially effective for fill-flash portraits in daylight since you can:

(1) Obtain belter background blur with a larger aperture.

(2) Create a catchlight in the subject's eyes.

(3) Soften shadows on the subject's face.
