I don't know about the 5D forum, but the Rebel forum and 7D forum have all but closed down due to this issue. Than fanboys are extremely vocal. They deny any reviews or data that indicate Canon is behind in sensor development. If that does not work, they claim that more DR is absolutely useless and results in poor photographic results. If that does not work, they get nasty. When they get nasty, the DPR moderators close the thread instead of taking action against the fanboys. A few years ago those were helpful and active forums. Now they are only a place for newcomers to ask a few questions. No serious discussions are possible.
