Canon 580ex ll Flash not working on my Canon 60D
I cant get my new 580ex ll external flash unit to work on my 60D. The flash connects properly, contacts are clean etc... The flash recognizes changes that I make to exposure compensation and zoom ( lens is Canon 24-105 zoom) as shown on the flash LCD panel. In ETTL mode however, the small lighting bolt that is supposed to show in the lower left of my viewfinder is not there. I have checked the flash control menu settings and the flash is [enabled] in [E-TTL ll mode] etc... I reset the C.Fn settings. Also, I tried the flash on my Canon 20D and it work just fine. Am I missing something obvious? Any help would be greatly appreciated.
