Contrast-Control-Sync Flash

Using AF330FTZ/AF500FTZ with AF360FGZ or 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.157)

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.

• For contrast control synch flash photography when using two external flashes, the flash set as the contrast control flash is flash 2, and the other external flash is flash 1. When using an external flash with the built-in flash, the built-in flash is flash 1, and the external flash is flash 2.

When using two AF360FGZ units or an AF360FGZ unit with the built-in flash, P-TTL is used for flash control. Other flash combinations use TTL.

The fastest flash synchronization speed is 1/90 second in the Contrast- Control-Synch mode.
