With a bright f/2 maximum aperture and an ultra-wide 99.1° angle of view, this Samyang 12mm prime lens opens up dramatic perspectives for Sony APS-C mirrorless cameras. The fast aperture excels in low light and gives you creative depth-of-field control, while the advanced optical design—featuring hybrid aspherical, aspherical, and extra-low dispersion elements—delivers sharp, high-contrast images from edge to edge.

Overview

The Samyang 12mm f/2 is a compact, weather-sealed autofocus prime lens engineered for Sony E-mount APS-C cameras.
