Samyang AF 12mm F/2.0 Fuji X

Samyang AF 12mm F/2.0 Fuji X – Bright 12mm ultra-wide for astrophotography and landscape

The Samyang AF 12mm f/2.0 for Fuji X offers a bright ultra-wide view designed for landscape, travel, interior design and architectural photography. With an f/2.0 maximum aperture, it also performs well for astrophotography, letting you capture starry skies even when shooting wide open.

Autofocus update of a proven wide-angle design

Samyang updated its long-loved MF 12mm f/2.0 into this AF version to add modern autofocus functionality and a refreshed design. The lens retains the optical character that made the manual-focus model popular, while adding rapid autofocus for easier handheld and dynamic shooting.

Optical construction and coatings

The lens uses a 12-element, 10-group optical layout that includes five special glass elements: one H-ASP, one ASP, and three ED elements. These extra-low dispersion and aspherical elements help minimize chromatic aberrations and distortion, producing sharper images from center to edge.

In addition, Samyang applied UMC (Ultra Multi Coating) to the lens elements. This coating reduces surface reflections, helps prevent flare and ghosting, and improves light transmission and contrast for cleaner results in challenging light.

Compact, lightweight metal body

The AF 12mm is compact and light. It weighs only 213g and measures just 59.2mm in length, striking a balance between portability and optical performance. The housing is all metal and the lens is weather-sealed, so you can use it in harsh conditions with added confidence.
