Just been looking at 7D sample images on Imaging Resource. Can anyone
explain the lack of detail in the red fabric on the 7D compared to the
40D (The red fabric in the top left of the photos, in the 3 o' clock
position):

40D, ISO 3200:

7D, ISO 3200:

It's the over-enthousiastic noise reduction. The version without noise
reduction is much better.

And yet it appears only to affect the red channel. The proportional
scale on the right and the other colors seem unaffected. In fact, the
scale shows more detail from the 7D.
