Anyone in the same boat as me. I have a Canon digital rebel and a 550ex flash and a ste2 transmitter. I cant seem to get the flas to work right with the camera. I put the setting to a-dep The only way it would work correctly is if i used the ste2 transmitter with it, and set it for slave. And even then i didnt get consistant results. Anyone in this same boat. Let me know if there is something simple or another flash that would work better. I was considering going back to manual and getting an TTL bare bulb flash.. Any input would be great. I use this for weddings and sports shots. So each photo is very critical
