Contrast-Control-Sync Flash

Combining two or more AF360FGZ or using AF360FGZ in combination with the built-in flash allows twin flash photography (contrast-control-synch flash photography). This is based on the difference between the amounts of light discharged from two units.

• 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 PENTAX dedicated automatic flashes.

1Connect the external flash to the camera indirectly. (p.159)

2Set the sync mode for AF360FGZ to the Contrast-Control-Synch mode.

3Turn the mode dial and set the exposure mode to e, b, c or a.

4Confirm that both the external flash and built-in flash are fully charged and then take the picture.

• When using two or more external flashes and the Contrast-Control-Synch mode is set on the external master flash unit, the flash output ratio is 2 (master unit) : 1 (slave units). When 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 two AF360FGZ units or an AF360FGZ unit with the built-in flash, P-TTL is used for flash control.

•The fastest flash synchronization speed is 1/180 second in the Contrast- Control-Synch mode.
