I agree on the rule of thirds in the viewfinder. I recently looked up a new viewfinder screen for the 5D with an etched thirds intersecting lines, something like $129 usd. Seems a bit overpriced to me. They dont even make one for the 20D that I can find. Why couldnt all the settings (histogram,etc) be controlled with the big wheel and shown on the view screen one at a time.
