Interesting article on DxO about 5D III and D800 resolving power

The article premise is a lot of hooey about nothing.
In reply to Hans Kruse, Apr 5, 2013

Here's what the article boils down to:

"From our recent Nikon D800 overview it’s clear the camera is the leader in outright P-Mpix (Sharpness) and overall DxOMark scores, but the rival Canon EOS 5D Mark III is not as far behind as the pixel counts suggest."

So what? Is someone actually thinking there would a 1/3 improvement in IQ in the D800 vs the 5D3?

Until someone actually shoots both cameras with the same lens (fairly easy to accomplish but not sure why this isn't being done by review sites - buy a couple of Zeiss or Sigma 50s in Nikon and Canon mounts for God's Sake) and compares the images on the same media, no one knows what the visual impact of one camera over the other really is. For example, it may be unfair to compare systems like the D800E/24-70G to the 5D3/24-70 II since the 24-70 II is such a great lens. In November, I shot the 5D2/24-70 II vs. the D3x/24-70G and much preferred the Canon files (mostly due to the lens). I am also confused by the reference to the P-Mpix score in an artcile about cameras since this score is lens related.

I have both the 5D mkIII with the Canon 24-70 f/2.8L II and 70-200 f/2.8L IS II (and more) and the D800E with the Nikon 70-200 f/2.8VRII. To my eyes there is little to distinguish the resolution between the 5D III with the 70-200 and the D800E with the 70-200.

I'm also shooting with a Phase One IQ160 and the resolution of the 60MP of this camera is heads and shoulders above the two DSLRs! There are no measurements of the Phase One cameras with lenses on DxO, but my feel is that the IQ160 resolves at least 50MP or more with the best lenses.
