Well, if it helped diagnose the issue then that is a good thing. Did you mean firmware for the 70D?
Also, on the magic lantern front - a different thread - matching the firmware is important, and ML for 70D is still at the beta level we think, so caution is advised. Works perfectly on my T3i however.
Good luck.
No the firmware on the 420EX. When I place this flash on either of my two cameras and go to Flash control then to "External flash C.Fn setting". I get the following message "This menu cannot be displayed. incompatible flash or flash's power is turned off". Now the flash is on and changes made to the focal length it picked up by the flash. So since the 420EX is not communicating with either of my cameras for this sub-menu item, then I think it's an issue with the firmware. Canon did discontinue the model a while back and they did produce a 420EX II, which was also discontinued.
