Using the Flash

5

As with the built-in flash, red-eye reduction is available with an external
flash. This may not be available on some flashes or may have restrictions
for usage conditions. See the chart on p.134.

Red-Eye Reduction

• The red-eye reduction feature works even when only an external flash is

used. (p.66)

• If red-eye reduction of the built-in flash is used when the external flash is set

as the slave unit or with the wireless function, the preflash for red-eye
reduction will trigger the external flash. Do not use red-eye reduction when
using a slave unit.

Wireless Flash Control (P-TTL Flash Mode)

When using external flash units (AF540FGZ or AF360FGZ) for
wireless shooting, the following information is exchanged between
the flash units before the flash is discharged.

Press the shutter release button fully.

1 The flash unit directly connected to the camera emits a control

flash (relays the flash mode of the camera).

2 The wireless remote flash unit emits a test flash (relays

confirmation of subject).

3 The flash unit directly connected to the camera emits a control

flash (relays flash output to the wireless remote flash unit).

* The flash unit directly connected to the camera will emit a control

flash one more time after this to relay the flash duration time when
HS

b (High-speed sync) is set.

4 The wireless remote flash unit discharge as main flash.

When the wireless mode of the external flash directly connected to the
camera is set to [MASTER] or [16. Flash in Wireless Mode] (p.138) is set
to [On] for the built-in flash, all the flash units will discharge
simultaneously.
