Using the Flash
9
Combining two or more external flashes (AF540FGZ, AF360FGZ or
AF200FG) or using an external flash in combination with the built-in flash
allows multiple flash photography (contrast control sync flash
photography). This is based on the difference between the amounts of
light discharged from multiple units.
1
Connect the external flash to the camera indirectly.
Refer to p.250 for details.
2
Set the sync mode for the external flash to contrast-
control-sync mode.
3
Confirm that both the external flash and built-in flash are
fully charged and then take a picture.
Using the Contrast Control Sync Flash
The AF200FG must be combined with the AF540FGZ or AF360FGZ.
When using two or more external flashes and the contrast control sync mode
is set on the external master flash unit, the flash output ratio is 2 (master unit)
: 1 (slave units). When an external flash is used in combination with the built-
in flash, the flash output ratio is 2 (external flash) : 1 (built-in flash).
When using multiple external flashes or using an external flash with the built-
in flash, P-TTL is used for flash control.
