i wonder if anyone else has seen this issue with the cactus v4 triggers - its really got me confused.
I have two receivers and one transmitter, what i am finding is happening is that i have one receiver on an old sigma flash and these seems to always fire reliably no issue. The other trigger though is connected to my AF540 flash an i often am finding that the trigger is activating the flash late. That is i can see the flash fires however there is no light entering the camera - this is when the shutter speed it set anywhere between 60 and 160.
If i reduce the shutter speed to say 1/2 second then sure enough the flash light appears as expected.
At first i though that maybe it was that receiver - so i swapped them over - but no the delay remains with the pentax flash.
The flash works perfectly when attached to the camera....
so anyone have any idea cos im beat??
