3 out of 10 points and not recommendedresolutioncolour aberrations,distorshon on full zoom band.
I've just bought it. I'm upset. I expected much more from Nikon. The single advantage of that lens is the resolution. But it's not ectraordinary resolution. It's simply normal, like all other lenses have.reviewed September 20th, 2013 (purchased for $500)
As for distortion, colour aberrations, vignetting these parameters are quite pour.
I've put some referrnce of the test photos below. It could give you some impressions about that lens:
Anyway 600 USD is not fair price for that lens. The price should be less than 300 USD.
So think twice before you will decide to buy that lens.
