Gerard, I just did a few tests as well. 30D and a Sigma 500 Super. The conclusion is, that I can NOT reproduce your tests, since the flash unit AUTOMATICALLY turns off the FP mode when shutter speed hits 1/250. So, it is not really possible to test for this bug, as I can not shoot with FP mode and 1/250 shutter speed.
Maybe it is the flash unit, maybe the camera, I don't know which one turns the FP mode off, but it only seems logical that it is the flash unit. I can't get a hold of a Canon flash right now, but I will be attending a conference, where I am sure may photographers will be, and I'll ask some to do some tests with their setups. hth, Miha. > -----Original Message----- > > Before jumping to conclusions, I did many tests: > > 5D+ST-E2+580EX > 5D+550EX(master)+580EX(slave) > 5D+580EX(master)+550EX(slave) > 5D+580EX - on camera > SAMO NASLOVNIKU! / ONLY FOR THE INTENDED RECIPIENT!
