Hi,

I have an issue with wireless flash. I have two external pentax flashes (AF 540FGZ & AF 360FGZ). I can successfully trigger either (or both) of them as wireless slaves using the K-5 built-in flash (as master or control). I've been doing this for some time with no problems.

However when I mount one of the external flashes ON THE CAMERA & set it to master or control, it will not trigger the other flash in wireless mode.

I feel like I'm banging my head against a wall. I've checked & double-checked the manual and as far as I can see, this is supposed to work (and it should also allow me to use HSS mode, which is the main reason I want to do this). But I can't get it to work at all even at low shutter speeds.

I thought at first that one flash may be faulty, but both of them behave in the same way - i.e. it doesn't matter which one I mount on the camera, it won't trigger the other one wirelessly...

Anyone have any ideas about this?

P.S. I should add that I checked they are both using the same channel...
