Overview

The Nikon Z 20mm f/1.8 S is a professional-grade ultra-wide prime for Z-mount cameras, offering excellent sharpness and fast f/1.8 aperture. Its S-Line build is weather-sealed with a metal mount and smooth electronic focus ring. Weaknesses include noticeable barrel distortion (2.1%) before correction and a relatively high price around $1150. It suits landscape, architecture, and astrophotography, with good coma control.
