Samyang AF 12mm F/2.0 Sony E

Samyang AF 12mm F/2.0 Sony E – Ultra-wide f/2.0 lens for astrophotography and landscape work

The Samyang AF 12mm F/2.0 Sony E combines an ultra-wide focal length with a bright f/2.0 aperture. It suits landscape, travel, interior design and architectural photography. In addition, the f/2.0 brightness makes it well suited for astrophotography, enabling you to capture starry skies even when shooting wide open.

Optical design and image quality

The lens uses a 12-element, 10-group optical construction with five special glass elements. Those include one H-ASP, one ASP and three ED elements. This optical recipe reduces chromatic aberrations and distortion. As a result, the lens delivers sharp images from the center to the edges of the frame, even at the maximum aperture of f/2.0.

Samyang also applies UMC (Ultra Multi Coating) to the elements. This coating helps reduce surface reflections, prevent lens flare and ghosting, and improve light transmission and contrast for clearer results in challenging light.

Autofocus, handling and build

This model adopts an Autofocus system in a compact and modern design. It offers rapid autofocus performance, making it practical for fast-paced shooting situations. The lens housing is all metal and features weather-sealing, so you can use it in harsher weather conditions with added confidence.

Weighing only 213g and measuring just 59.2mm in length, the AF 12mm f/2.0 balances portability with performance. Samyang states this is the lightest and smallest AF 12mm lens currently on the market, which makes it especially attractive for travel and on-location work where weight and size matter.
