Samyang AF 12mm f/2
A bright f/2.0 aperture and linear STM autofocus deliver sharp low-light imagery in this 213g, weather-sealed lens. Its 12-element optical design with three ED elements minimizes coma for astrophotography, and the 62mm filter thread adds versatile field practicality. This 12mm prime best serves Fujifilm X-mount astrophotographers and landscape shooters who need a compact, weather-resistant ultra-wide that accepts standard screw-in filters.
