Don\'t forget that for the same pixel sharpness the 7D NEEDS SHARPER LENSES THAN THE 5D2 since its photosites are much smaller and its absolute resolution is higher.

You are claiming that the 7D NEEDS SHARPER LENSES THAN THE 5D2.
But as I said already, the new G11 has a 9x smaller sensor than the 40D - and yet, they are equally sharp.
So, lens sharpness does not seem to be a good explanation why the 7D is softer than the 5DII.
I\'d say it\'s the sensor.
If you tested absolute resolution of the G11 lens against all of the Canon L\'s, the G11 lens would probably beat them all by quite a margin. P&S lenses are jewels compared to 135 format lenses. They have to be much sharper in absolute terms, and they are.
The 7D on the other hand can use full frame lenses such as those which fit the 5D2. It is the highest absolute resolution EOS camera ever made and as a result the 7D\'s per pixel sharpness tests EOS lenses harder than any previous body.
If you put L lenses on a G11 or G10 the results would be surprisingly bad.
