Flash the Using

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 test flash (relays the flash mode of the camera).

2The wireless flash unit connected to another flash unit emits a test flash (relays confirmation of subject).

3The flash unit directly connected to the camera emits a test flash (relays flash output to the wireless flash unit not directly connected to the camera).

* The flash unit directly connected to the camera will emit a test flash one more time after this to relay the flash duration time when HS b (Highspeed sync) is set.

4The wireless flash unit connected to another flash unit discharges as main flash.

When the wireless mode of the external flash on the camera is set to [MASTER] or [29. Flash in Wireless Mode] (p.146) 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.143.

• The red-eye reduction feature works even when only an external flash is used. (p.64)

•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.

Trailing Curtain Sync

When using the built-in flash with an external flash (AF540FGZ or AF360FGZ) that is set to the Trailing curtain sync function, the built-in flash will also use this mode. Confirm that both flash units are fully charged before shooting.
