Yesterday, I set up my ST-E2 on camera (EOS 40D) with my two 550EX flashes on stands. I wanted to shoot the flashes in manual mode at 1/32 - 1/16 power settings, but discovered that the flashes will only work in ETTL mode with my ST-E2.
I tried to set the flashes to manual mode but nothing happens - the mode won't change.
There must be some way to fire them manually with an ST-E2. Surely Canon, in their great wisdom, didn't set this up as an ETTL only system!?! Tell me it ain't so! Please!
Is there any way to overide this so that I can set my flashes in manual mode and have the ST-E2 trigger them?
