Zeiss 21mm f/2.8 Distagon on Nikon D800E (Green Hills)
Added to Guide to Zeiss is a detailed study from f/2.8 - f/16 using the Zeiss 21mm f/2.8 Distagon on the Nikon D800E.
This second study supports the results seen in the Pine Creek Tungsten Mine study with a plain but instructive scene that removes any doubt about the optical behavior. The 36-megapixel Nikon D800E is a demanding taskmaster for any lens.
