Using the Flash
5
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.
Red-Eye Reduction
• 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.
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.
↓
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 control 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 flash 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 [31. Flash in Wireless Mode] (p.177) is set
to [On] for the built-in flash, all the flashes will discharge simultaneously.
