Hello, can you help me, please? I need an ultra-wideangle lens for my Nikon D810, for mountain landscape shoots, at f/8 and f/11. I don't know which one I could choose. My doubt is only between two lenses: Nikkor AF-S 14-24mm f/2.8 and Zeiss Distagon 21mm f/2.8. I know very well the rendering of Nikon 24/1.4G, 35/1.4G, 24-70/1.4G and I love them. AF isn't a priority. The versatility isn't a priority. Budget is not a problem for 14-24mm or Zeiss 21/2.8. My problem; is the Zeiss Distagon 21mm f/2.8 really more sharper than Nikon 14-24mm f/2.8? Is the corner sharpness better in the Zeiss 21mm f/2.8? I don't know Zeiss lenses, only their fame.... I have seen photozone.de values and there Zeiss 21mm's corner sharpness isn't better than the Nikon 14-24mm: are you agree? Are Zeiss's contrast and saturation better than Nikon 14-24mm? For me a Zeiss Distagon 21mm f/2.8 and a Zeiss Distagon 18mm f/3.5 are sufficient as focals: I don't need 14mm......, but if Nikon is better, i would choose 14-24mm.
Thank you!!
