Steve Parrott wrote (edited): One poster mentioned if the flash was zooming with the lens. I had not thought of that, so I made sure and checked that out. Yes, the flash does zoom with the lens when mounted on the bracket.
Another poster stated that he used a bracket that rotated his camera but not the flash, and had no lighting problems like mine. All I can say is, consider yourself lucky. Are you using a wide angle lens? I have not taken test photos in small increments to see *exactly* when the problem gets it's worse. I do know that at 70mm, the problem is very slight to almost non existent, but at 24mm the problem is EXTREME. Just picture placing a horizontal rectangle of light against a vertical rectangle of darkness. The center of the scene is lit, and the top and bottom are dark, or at least much dimmer than the center. I have to agree with those who state I am just using the wrong type of flash for the situation. I checked the Quantum Qflash unit, but I really don't want to invest a $1000 to cure this problem. I will just continue to use a bounce deflector on my 550. ---------------------------------------------------------------------- Steve, I wrote asking about the zoom. I still disagree with the 550EX being the wrong flash. I would say there are two possibilities. First the flash may be positioned directly ahead on bracket. It may be best if there is a slight downward tilt. I think this is not it though. The other thing is to check it with another 550EX and see if it does the same thing. If it does, then the firmware in your 1D may be incorrectly setting the zoom position on the to match your lens.
