Overview

The Samyang 20mm f/1.8 is a manual-focus wide-angle lens for full-frame cameras, offering excellent sharpness and a fast aperture suitable for astrophotography. Optically, it is very sharp but produces a clinical, characterless image. Build quality is good with smooth rings, though the lens feels plasticky and is large on mirrorless bodies. It lacks weather sealing and electronic contacts. Best suited for budget-conscious landscape and astro photographers who don't mind manual focus.
