On attaching the 580EXII to camera T4i/650D the flash will not display ETTL mode. Camera Flash control menu (function settings/C Fn settings) displays incompatible flash or flash power turned off. However, if you change C.fn function 05 on the flash ensuring 05 0 is displayed it will then display ETTL ON THE FLASH. Sadley once attached to the camera and shutter release pressed, flash reverts to TTL mode and flash won't fire. Help would be much appreciated ! Would very much like to use as a master with my two 430EXII. Cheers!
