As Brian says, this reviewer can safely be ignored. I looked at his separate comparison of the D7100 vs the Pentax K5 IIs - basically he loaded both cameras' files into Corel and auto-balanced them, which he says processes the RAW files as intended by the manufacturer. Firstly, none of the manufacturers share their proprietary RAW file architecture with third party software vendors, so auto correction of RAWs is pretty much guess-work. Secondly, if you have ever used the 'Auto' button on any PP software, you'll know the results are wildly unpredictable even on files from the same camera, let alone files from different manufacturers' cameras.
This guy has a serious axe to grind with Nikon and his testing is neither scientific, nor objective......
It's also interesting that he quotes DxOMark's results to support his conclusions when the D7100 scored higher than the K5 IIs in three out of four tests and came out better overall.
