When I choose External Speedlite control/ Flash function settings on the 5D.
I get a dialogue that says
This menu cannot be displayed. Incompatible flash or flash's power is turned off.
Flash is on. If I take a photo, flash fire's. Pictures are ALWAYS over exposed when using the flash.
Does the 580EX II work with the 5D Mark III?
Solved! Go to Solution.
