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 PENTAX automatic flashes.

1 Connect the external flash to the camera indirectly.

Refer to p.169.

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

4 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.
