DxOMark published their test results for the Nikkor 20mm f/1.8G ED lens ($796.95, see review):
“With an overall DxOMark Lens Score of 33 when tested on the D810, the Nikon 20mm f/1.8G ED ranks in 158th place for all lenses tested, but more importantly, it comes in first for Nikon FX-mount 20mm prime lenses. Up against the slightly longer focal length of the 24mm Nikon and Samyang wide-angle lenses, the new 20mm Nikon drops into 3rd place overall, again tested on the D810, but displays good results in all of the lens metrics sub-categories.”
