That is very disappointing, but not entirely unexpected (given previous poor reports), news David. It seems Canon have made a major "faux pas" with this camera and it's just not up to the standards you would normally expect from such a reputable company. For a camera which costs such a large amount of money too this is doubly disappointing. Perhaps the holy grail of full frame digital cannot be obtained at a "budget" cost and Canon, in their efforts to provide such a camera in such a price bracket, have for once taken their eye off the ball and let standards slip. A camera which vignettes is simply not acceptable in any shape or form never mind at this price bracket and the 5D has done no favors to Canon's reputation and I think will make prospective future purchasers of their products more wary of purchasing on reputation only from now on.

So it's to be a 30D until Canon can get their act together then? Well at least the 20D was a proven performer and the additional tweaks the 30D provide should make it even more worthwhile.
