This is a lens testing site though. The results shouldn't be polluted by a sensor issue.
I will publish the results though - although I don't think that the Sony community will like this.

This may be a lens test site, but given the method used, Imatest, the actual test is always of a system. A system containing a lens, usually an AA filter, some other filters, micro lenses etc. And there is a RAW converter. All these things influence the results. Tests where preformed with range finder lenses on the NEX-5. This is not a brilliant combination and the results reflect that. The same lenses will almost certainly give other results on another camera. The NEX-5n seems to be best NEX, with rangefinder lenses. And the difference between the 5n and the 5 is significant.
As example of the influence of the complete sensor system; when I compared results of a Nikon 16-85 on a d7000 and a NEX-5n, the later shows clearly better micro contrast, at least giving the illusion of more detail.
And the Sony CZ24-70 used on a NEX-7,at least my copy, beats any lens/camera combination I have ever seen, including the same lens on a Sony a900. Corner to corner. And completely contrary what other results suggest, the 24-70 is already very good with the lens wide open (in the shorter range of the lens).
It is a pity that Sony did not use the improvements made in the 5n for the 7. But even so, it can still be a brilliant camera. We are so spoiled with great gear nowadays. This little wonder give me better results than I ever got out of my Mamiya RB 67 or my Linhof super Technika (6x7).
