Contrast-Control-Sync Flash

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.

•Do not combine with accessories that have a different number of contacts, such as a Hot Shoe Grip, as a malfunction may occur.

•Combining with flashes from other manufacturers may cause equipment breakdown. We recommend using the AF540FGZ, AF360FGZ or AF200FG.

Connect the external flash to the camera indirectly.

Refer to p.194 for details.

Set the sync mode for the external flash to contrast- control-sync mode.

Confirm that both the external flash and built-in flash are fully charged and then take a picture.

•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.
