Having said all that, it's not a surprise to me that DxO have found what they have. They are simply saying, in effect and perhaps without knowing it, that sharpness is perceived as resolution (even though it's not), and that, even though the 5D3 resolves less, it also provides higher acutance, so the net result is closer than you might, at first, think.

I remember a while back when someone took an original capture, and then decimated a copy with the Nearest Neighbor method, and fed both to Imatest, and Imatest reported the decimated version (IOW, the one with rows and columns of pixels stripped out of the image) as having higher resolution.  I'm afraid we might have a similar kind of folly here.

So are you dismissing the results and findings from DxO? Or is not more about how to interprete them? Do you think DxO uses Imatest? I don't find the relevance of the example unless you think that DxO are amateurs.
