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

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

3The 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 HSb (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.

Red-Eye Reduction

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.

• 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.
