The AF500FTZ can be connected directly to the Extension cord F5P without the off-camera shoe adapter F.

Contrast-Control-Sync Flash

Using the dedicated external flash 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. Contrast control synch flash is possible with the combination of following flash units:

AF360FGZ, AF330FTZ, AF500FTZ and the built-in flash

1Refer to page 97 for connecting the external flash off-camera.

2Set the synch mode for AF360FGZ, AF330FTZ / AF500FTZ to the Contrast-Control-Synch mode.

3Confirm 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.

Do not combine an accessory with a different number of contacts such as a “Hot Shoe Grip”, as a malfunction may occur.

The fastest flash synchronization speed is 1/60 second in the Contrast- Control-Synch mode.

Combining with flashes from other manufacturers may cause equipment breakdown. We recommend using the PENTAX dedicated automatic flashes.
