Just published: Nikon ultra wide zooms part 1
Just published in DAP are distortion and vignetting comparisons at 16mm, 17mm, 21m, 24mm, 28mm and 35mm for five Nikon zooms and the Nikon 20/3.5, 24/2, 28/2, 35/1.4. Also published is material on my own take on the various lenses. All comparisons made on the 24 megapixel Nikon D3x.
Extensive comparison crops at those focal lengths are in progress and will be published soon, so as to show the optical performance of these zooms and primes.
