Look for example at the details on the rainpipe: the mounting screws
and the bending folds are almost invisible on the 20S pctures.

I still hold to my oponin looking at sharp branches and edge defination, as well as texture. (note there is 4 million pixel difference between the cameras, D300 file is more than twice as large as 20D file)

I do agree with the noise difference, that was also my observation.
But better hve some noise in the shadows than blown highlights of
important image parts.

I did mention this several times in my report.

If you expose for the same brightness of your pictures, taking into
account that the ISO values of the D300 are around 1/3 stop too
optimistic , you will see that the noise advantage of the 40D becomes
smalller.
If you would expose both pictures for the highlights then the overal
picture of the D300 would be brighter than that on the 20D however,
but noise would again become less and on par between both cameras
after resizing.

Whatever I do there are people who will say why did you expose for this, and why didn't you expose for that. I used an accurate exposure for the scene I intended to photograph and show the fall colors and contrast, based on what I know about histograms and both cameras had the same exposure, why would I force D300 to blow up? I didn't have the 40D so I wouldn't know what the reading on that camera would be.

I agree that nikon does not beat canon in noise, the more ore less
closed the gap but they did not take the lead.
That said, noise is one thing but as you said yourself, there is more
to it than only noise to evaluate the quality of a DSLR.

of course.

BTW: did you try the 3D tracking with CF-A1 set to focus priority?

Not yet, but I think dynamic 9-point is the best mode for me for tracking birds.
