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.
