I have a Canon 580 EX II flash and when it is not attached to a camera when I test the flash it kinda acts like a strobe and hangs a bit. Once attached to the camera it functions properly. Any idea what is going on? Does it need to be sent in for repair? HELP
It was not in strobe mode -
Check the Custom Function settings on the flash itself, sounds like it is set to fire the 'Modeling Light'.
