Using the Flash
5
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.
Red-Eye Reduction
• 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.
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.
È
1 The flash directly connected to the camera emits a control flash
(relays the flash mode of the camera).
2 The wireless remote flash emits a test flash (relays confirmation
of subject).
3 The 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.
4 The 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.
