I was shooting a friend's party tonight and my camera started to doing some weird stuff... a case of bad time for bad timing issues.
My 30D had a 580Ex attached with a Lightsphere II (Fong Dong) in use.
After taking 15 or so shots, my chimping picked up that the shutter was not opening at the same time as the flash was firing... meaning that the shots were pretty much black in the dark venue we were in.
I powered everything down, took the batteries out, cleaned the flash connectors, made sure that the flash was clicked into the upward position... no luck. I tried shooting with the flash in manual mode, but that was hit and miss too. This was the camera set up:
30D Camera: 400 ISO 1/60 F4
580Ex Flash: ETTL +1/3 pointed up with the Fong Dong attached.
Does anybody know what would cause this to happen? Does the 580Ex eventually die or need some sort of repair as a result of these symptoms?
Advice much appreciated!
