DxOMark published their test result and conclusion for the Nikkor 18-35mm f/3.5-4.5G ED ultra-wide zoom lens ($746.95):
“With the price close to the Tokina, this new Nikon’s ‘moderate to slow’ variable aperture, all-plastic construction and lack of an aperture collar may all be viewed as shortcomings. Looking on the up-side, the material choice means the lens weighs just 385g and yet, even after adopting a large 77mm filter size, it somehow retains relatively compact dimensions making it highly portable. As for the optical quality, it’s first class and will no doubt be a good match for the inevitable high-resolution bodies that must surely exist on the drawing boards of Nikon facilities in Tokyo and Sendai.”
