Is the Canon 30D noisier than the 20D?

Is it possible that the noise levels in the Canon 30D are worse than that of the ageing Canon 20D? According to this story it’s true! I find it hard to believe because the cameras are so similar – same sensor, same digital processor and more. I wonder how the 20D compares to the new Canon 400D?

Even if you don’t have any Canon equipment, the article takes a look at the RAW vs Jpeg debate too which might be less sensational but makes for a good read. (via)
