Hi, I just got a 550D after using 20D for many years. Last night when I tried using my Sigma EF-500 DG Super flash on the 550D, I had problems getting the flash triggered. Very erratic behaviour - most of the time flash is not triggered. But when it does the flash burst at full power.
Any Sigma EF-500 DG Super owners here? Mind sharing if your flash works with the 550D? Many thanks.
