6d External Speedlight Issue
Maybe someone has an idea what is going on.
I have a ST-E3-RT and 3 600ex-rt's that are working on my 5dII.
When I use them on my 6d (external flash enabled, flash firing enabled) the flash isn't firing. The weird thing is that the image meta data says the flash is firing. I tested this in multiple situations, the flash isn't firing.
I checked and I have full channel signal strength.
I'm guessing the meta data means it sent a fire signal to the radio transmitter. Pressing the test flash button the master flash unit always works.
It doesn't seem to matter which unit I set as the master (i used different 600's as masters and I'm having the same issue as with the ST-E3-RT.
I'm guessing something with my 6d settings is messing up what I want to do. Any ideas?
Any help is much appreciated.
