I think the shots pretty clearly show that the master flash is firing at exposure time in *some* of your photos, and not in others. There may well be a problem, but I'd bet that it's with the EF-500, not with the Elan 7. There were definite limitations on what the Elan II could do with ETTL wireless flash. These limitations are spelled out in the 550EX's manual (The EOS 3 will do so-and-so, but the Elan II and Rebel will not). But in the manual for the 420EX, a flash released with the Elan 7 and marketed as the right companion flash for it, I don't think any such limitations are mentioned. Unfortunately I no longer have that manual so someone who does have it should correct me if I'm wrong, but I know that the 420EX can, for example, be in multiple slave groups when used with the Elan 7 but not when used with the Elan II. It's very hard to imagine that Canon would have picked an arbitrary subset of wireless flash features to leave out of the Elan 7. On the other hand, the Sigma flash is known (by me from personal experience) to be an imperfect knockoff of the 550EX. For example, it doesn't work with Canon Powershot digital cameras like the G1 and G2, although the Canon EX flashes do. So I'd check and see if the Sigma is the cause and whether it can perhaps be updated or repaired. --Ken S. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
