Review: Nikon 35mm f/1.4G compared to Nikon 35/1.4 AI-S and Zeiss 35mm f/2 Distagon
Just published in my review of the Nikon 35mm f/1.4G is a 3-way comparison with the Nikon 35mm f/1.4G, including distortion, vignetting and of course, sharpness.
Also, see the new comments I've added regarding the 35/1.4G focusing problems.
