Remote triggers with the AF-560...

Hey there I'm just playing around with some off camera eBay flashes triggered by remote(ctr-301's) it all works fine except when I use my AF-560 flash they wont sync with a shutter speed of more 1/30th, the flash still fires and the camera fires but no flashgun light is captured!

Anyone know how to fix this issue or what the cause may be?

Regards
Simon

Are you using the 540 in manual mode? Try replacing the batteries in the triggers.

The low trigger voltage of Pentax flashes can cause slow sync problems with these radio triggers. The internal circuitry has just a little too much voltage drop. I fixed my Cactus triggers by connecting the negative battery terminal to the hot shoe ground plate, bypassing one of the components in the reciever. Maybe something similar would work for your triggers. Here's the thread where I discuss this:
