Any kind soul out there knows why 580EX cannot change from TTL to ETTL by pressing the "Mode" button when attached on an EOS 5D Mark II? Some setting problem? There is no loose contact at the Hotshoe. Could it be an upgrading of firmware to 2.09? Thank you!
Thank you guys for your replies. I have set all Cn Functions on both the flash and the camera to the original but the flash still goes full blast over exposing all shots. The camera cannot detect the flash and the flash display shows TTL all the time. Will be sending to the service centre because no idea what to do next .... maybe really faulty hardware...
