I have a canon 40d and 24-70 lense. I just purchased the above canon flash and the flash cord to attach to camera hot shoe and bracket. I want to start to shoot in ettl mode . I was with a photographer and saw just about every image was on the money and gorgeous. I was shooting manual flash and camera on manual ( I am an old time photographer ). I like the results and will start to shoot this week with my New canon 580 ex ll. Any advice on what to do or how to set up my flash, camera etc. Greatly appreciated, rollsman
