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.
1 Connect the external flash to the camera indirectly. (p.159)
2 Set the sync mode for AF360FGZ to the Contrast-Control-Synch mode.
3 Turn the mode dial and set the exposure mode to e, b, c or a.
4 Confirm 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.
