I have a Canon 5D MK IV and have just purchased a Canon 580EX (not EXII) however using the camera menu the only function available is exposure compensation, ettl, second curtain sync and FEB are all greyed out, according to the specs the 5D MKIV is compatible with the 58 EX speedlite, any ideas why it doesn't work?
