I recently purchased a Canon EOS 6D, but my Speedlite 430EX II is not working with it. Is this flash not compatible with the 6D? When I go to Menu –> External Speedlite Control, flash firing is enabled.
However, when I press ‘Flash function settings’ or ‘Flash C.Fn settings,’ it says “This menu cannot be displayed. Incompatible flash or flash’s power is turned off.” (power is definitely not turned off :))
What is the issue?
