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 test 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 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 [17. Flash in Wireless Mode] (p.166) is set to [On] for the built-in flash, all the flashes will discharge simultaneously.

Red-Eye Reduction

As with the built-in flash, the red-eye reduction function is available with an external flash. This may not be available on some flashes or may have restrictions for usage conditions. Refer to the chart on p.162.

•The red-eye reduction function works even when only an external flash is used. (p.71)

•If the red-eye reduction function of the built-in flash is used when the external flash is set as the slave unit or with the wireless function, the pre-flash for red- eye reduction will trigger the external flash. Do not use the red-eye reduction function when using a slave unit.
