Zeiss 21mm f/2.8 Distagon on Nikon D800E (Pine Creek Tungsten Mine Bldg)
Added to Guide to Zeiss is a detailed study from f/2.8 - f/11 using the Zeiss 21mm f/2.8 Distagon on the Nikon D800E.
Like the 35/1.4 study using the same scene, this study is quite revealing of the behavior of the 21/2.8 Distagon. I believe it will be helpful to any 21/2.8 Distagon user.
