Trying to figure out what in the world is the deal with my 550 sigma flash. It's the sg model I think. I haven't used it much since I have fast lenses but last night I tried to, and when I had it on ttl the image was almost completely white. I tried max and min and neither looked right. This was in aperture mode. Shoudn't I be able to just put the thing on ttl and let the camera regulate the light for a good photo??? This is a 20d. Thanks

Has it ever worked on you 20D? I know alot of those non Canon flashes quite often mysteriously don't work with newer models.
