I'll take that bet ...... but only after we carefully define what we mean by "about".
With the same lens and same everything else - including the same cropping to show the same amount of the bird - images from 20D, 40D, 50D, and 1D III are indeed about
the same. None of them are mind-blowingly different from one another. All of them are way better than anything you'd get with a P&S.
But there are
differences. How much is "about"?
