Sorry if wrong yet I struggled for an eternity with this issue with my old 5DII & two 550ex's...

I then found that with the camera in A or P mode the flash simply operated as a reduced power 'fill in flash' for lighting back lit subjects etc !!. You had to use m/av/tv to get out of this mode...

Canon have a detailed paper on this. I'll try to find a link to it when my sons get off the pc's


That would be interesting because there is an interesting conversation at POTN about how does flash metering work. There are claims even though Canon claims A mode is fill someone did a series of tests and stated he proved this was not so. I won't be back until tomorrow as I am going out of town in the next hour.
