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.

1The flash directly connected to the camera emits a control flash (relays the flash mode of the camera).

2The wireless remote flash emits a control flash (relays confirmation of subject).

3The flash directly connected to the camera emits a control flash (relays flash output to the wireless remote flash).

*The flash directly connected to the camera will emit a control flash one more time after this to relay the flash duration time when HSb(High- speed flash sync) is set.

4The wireless remote flash discharges at the same time as the main flash.

When the wireless mode of the external flash directly connected to the camera is set to [MASTER] or [31. Flash in Wireless Mode] (p.177) is set to [On] for the built-in flash, all the flashes will discharge simultaneously.

Red-Eye Reduction

As with the built-in flash, red-eye reduction is available with an external flash. However, depending on the type of the flash, this function may not be available or may have some restrictions for usage conditions. See the chart on p.173.

• The red-eye reduction function works by discharging the flash twice even when only an external flash is used. (p.75)

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.
