Pentax K70 - optical trigger AF360FGZ in dumb slave mode

[andrewk]

Hi folks,

Partly for my own amusement, I have been trying to get my K70 (in manual flash and manual exposure mode) to optically trigger a remote AF360FGZ (in dumb slave mode - SL2) - but am having no success at all.

The AF360FGZ works fine in every mode when mounted on the camera's hot shoe. The flash will trigger fine when using a K30's pop up flash on P-TTL (but obviously not a K70, as it does not support a master/slave P-TTL mode), As far as I can tell, I have set everything as I should - but the remote flash just will not fire using a K70.

I have also tried this with a Yongnuo 560 iii (manual flash), with the K70 set on manual exposure and manual flash and the Yongnuo set on slave 1 (fire on first optical flash received) - and it works first time, every time.

I have read in a number of places that a K70 on manual flash should optically trigger a Pentax flash that is in slave mode 2. Has anyone else tried this and actually got it to work? If you did, can you explain how - in words on one syllable? I have already tried the RTFM bit - and it didn't work.

Help!!
Andrew

I've had another play with the K70 and AF360FGZ. It will flash, triggered by the K70 pop-up, in manual, slave, slave mode 2 - but only if the K70 is set to normal flash - not manual. Weird ........
