Hi all,
I have a 580ex11 hooked up to a wireless receiver, and have it set as a master for the canon infrared to trigger the 430ex. It triggers the 430 fine, but the 580 will only work on ettl, and not very well(low light). It won't work on manual at all. does anybody have any ideas on this? is this normal? the 580 works fine as a master on camera. I haven't tried it on cord though but I would expect it to be fine, unless they don't work as masters through the pc. Any info would be a great help
Mark
