I've briefly glanced at this thread and don't really want to get too involved, but I just want to make a couple of points to make you think outside the box.
Firstly, you can speculate all you like and read as many reviews as you can, but lens design and lens quality cannot be judged by theory or which manufacturer has made it. They all have there own merits and flaws, and it depends on which camera they're attached to.
I have a Nikkor 14mmf2.8. Fitted to the D2x, at the edges of the image, the definition is terrible and there's a lot of chromatic aberration. Bear in mind that the D2x is cropping 50% of the image circle produced by the lens.
Place the same lens on the D3, (which now shows the full image circle) the edge definition is better and there is little chromatic aberration. One would have thought that after seeing the results of this lens on a D2x, it would become unuseable with a full frame sensor, but not so.
The 14-24mmf2.8 Nikkor zoom is far superior in edge resolution, chromatic aberration and distortion than the fixed 14mmf2.8. Goes against the theoretical rules.
Just a small example of what happens in the whole photography market.

There is a digital processing in the D3 and D300 which actually make corrections for lens flaw. It has been reported in some reviews. So your observation is not surprising. These 2 cameras actually improve the image captured by optic flaws. Try google, I cannot remember if it was dpreview of another site which reported this.
