I don't think DXO Mark lens evaluations are particularly useful for real life shooting.

The lenses resolve higher on full frame. When taking the test into account he should have shown their test against an APS-C sensor. It's still a much better lens, but it's much closer.

Sure, but I find that the DXO Mark is a test primarily about light transmission and a little bit about sharpness. Thinks like flare resistance, out of focus rendering, contrast, etc are not really addressed in such a number and therefore this is an inadequate evaluation of the lens performance versus each other. Photozone is a better way of looking at it. I do think the Nikon is a stronger lens, but the 16-50 is better than is indicated by DXO Mark.
