You are using the wrong flash for the job. The Canon flashes are very tightly integrated to the 35mm format (OK for digital the 2:3 aspect ratio format). Zooming to match your lens focal-length, etc. For this reason (and to maximize the light/guide number (as mentioned in another posting)) the coverage needs to be rectangular. You need a different flash, like a Quantum Q-Flash or a Lumedyne. They'd give you square (round) coverage that will handle your rotating camera. ------------------------------ Sorry to disagree but the Metz flashes are NOT all square. Only the Metz 60 CT-1 had a near square head. The 60 CT4 had a rectangular head as does the 45 series and newer series. There should be no problem with the flash. I use a bracket with the 550EX and have no problems at all. What may be happening is that the flash may be in a manual zoom position for a longer focal length and he is using a wide angle lens, hence coverage may be less in one orientation.
