Thanks John, >But it should trip the flash up to whatever the sync speed of the camera.
That is why I am surprised. When I mount the mentioned flash units on the hot shoe, I can use the 1/180 second synch. Strange! Someone suggested that I might need fresh batteries; replacing the 12V on the transmitter didn't help. I will try again after replacing the 2x 1.5V ones on the receiver.
