Contrast-Control-Sync Flash

5
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.
The AF200FG must be combined with the AF540FGZ or AF360FGZ.
1
Connect the external flash to the camera indirectly.
Refer to p.173 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.
