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 have experience with neither lens, but at apertures of f/8 - 11, issues like wide-open vignetting and sharpness are not relevant. Most (all?) modern lenses (and even many not so modern lenses) will perform very well here. The main things to consider are contrast and flare as has been mentioned, and also:
- color rendition, contrast, distortion and other optical qualities. Mustache distortion might not be a problem for landscapes, but it is for sea-scapes
- size, weight, portability - is it a lens you can easily carry, or will you be tempted to leave it home because it is too big?
- AF vs MF performance - is AF accurate, for MF is the focus ring well damped with a long focus throw?
- filter size - does the filter size match other lenses you already have or will you need to buy another set?
- focal length - there is a big difference between 24 amd 14mm
