John B- I think you are DEAD wrong in saying the noise performance of the 40D is "neck in neck" comparable to the 5D... I will be posting a report shortly comparing noise with the 40D and its no better than the 30D. give me until tonight and you can look at the images yourself.
I was of the same opinion until I did my own test with all setting equal, found the 40D to be just as good as the 5D even interpolated to the same size.
or (and no disrespect meant to you here, but) you may need a lesson in exposure. The 40d is not as lenient on exposure as the 30d - so a bad picture does look bad. ( the 10.1 mgp will do that )
