Can I run the Pentax AF-540 Flash in wireless optical slave mode ?


I want to use my AF-540 flash in wireless mode (as slave), but trigger it from another flash, the Canon 580 II.

It works great with my built-in flash of my K200D, but doesn't respond to the Canon, even though they are both set to M (so no TTL conflicts should exist) and to the same channel.

I'm not sure, but shouldn't my AF540 fire whenever it sees another flash (like all these cheap "stupid" optical-triggers on ebay) ?
I know he can do even better (P-TTL), but why can't it also just run as a basic optically triggered flash ?

Am I missing something?

Slave 2 mode

  1. Set the flash to wireless.
  2. Set the wireless slider to slave.
  3. Press and hold the light button until Slave 1 appears on the LCD.
  4. Press the S button to set slave 2 mode.
  5. Press the light button to exit the screen.
The flash is now in optical slave mode.

Thank you

Thank You!

Thank you! I needed to test a new trigger, and couldn't find my manual. Thanks!

Does anybody know if it's possible to do the same with the Metz 58?
