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. (p.146)
2 Set the sync mode for the external flash to the contrast-control-sync
mode.

3 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 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 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 an external flash with the built-in
flash, P-TTL is used for flash control.
