Interesting to see that tests are sometimes not showing the performance of a lens.
This is a beautiful case.
If you see images taken at 1,4 with this lens you see a clarity that the other lenses miss completely.
It is among others the Nano-coating. As with Zeiss lenses that are T* coated- the coating makes a huge impact on the outcome.
Also you see in pictures taken with this lens a beautiful sharp- unsharp rendering. You can isolate subjects very nice with this lens. It is a good thing Nikon at last makes a standard lens with Nanocoating- but i find it way too expensive....
