Hi to all on the forum, I hope you may be able to help me with a problem.
First off the kit; 5D Mk11, 40D, 430EX and 580EX.
Historically I have hardly ever used flash as where I tend to shoot doesn't allow it or the results would be wrong.
The last gig, my sons wedding, almost became a disaster when I bolted flash guns to the cameras. Please bear with me as this seems to be complicated for a non flash user. Using tv mode, under sync speed, to help with dancing etc. the flash power and firing just seemed to be random, either not at all or full power burnout.
On examining the menu on the 5D Mk11 the following comes up: "External speedlite control"/"Flash function settings"; the first 3 items grayed out, the other 3 available; "Flash C.Fn settings" quote "This menu cannot be displayed. Incompatible flash or flash's power is turned off." Simillarly "Clear all C.Fn's says "This menu cannot be etc. All C.Fn's on the actual flash guns are set to 0, so as I understand it the cameras should control everything. I wasn't trying high speed sync or second shutter curtain stuff just straight forward flash assisted shots.
Mega frustrating on the day! However, sober experimentation at home shows the both combinations produce the same responses.
With respect to the forum, any ideas?
Pete.
