Samyang 12mm f/2.0 AF Ultra-Wide Angle Prime Lens for Sony E-Mount APS-C Cameras

Unlike typical ultra-wide primes that force manual focus or sacrifice speed for compactness, the Samyang 12mm f/2.0 AF brings fast, silent autofocus and a bright f/2 aperture to Sony E-mount APS-C bodies. This lens pairs a 99.1° field of view with weather sealing and an all-metal barrel, making it a dependable companion for astrophotography, architecture, interiors, and environmental portraits—even in challenging conditions.

Highlights

• Ultra-wide 12mm focal length (18mm full-frame equivalent) with 99.1° angle of view
• Bright f/2 maximum aperture for low-light shooting and shallow depth-of-field control
• Fast, accurate autofocus with manual focus override
• Weather-sealed aluminum alloy construction for durability
• Advanced optical design: 12 elements in 10 groups, including 3 ED and 2 aspherical elements
• 7-blade rounded diaphragm for smooth, pleasing bokeh
• 62mm front filter thread for creative filter use
• Included petal-type lens hood to reduce flare and protect the front element

In daily use

The 12mm focal length delivers an expansive perspective that pulls viewers into the scene. At f/2, the lens gathers ample light for handheld shooting at dusk or indoors, while the rounded 7-blade aperture renders out-of-focus highlights with a natural, circular shape. Autofocus is quick and quiet, making it suitable for both stills and video on Sony E-mount cameras. The minimum focus distance of just 0.19 m lets you get close for dramatic wide-angle close-ups with exaggerated foregrounds. The weather sealing adds peace of mind when shooting in light rain or dusty environments, and the metal barrel feels solid in hand. The 62mm filter thread accepts standard filters, so you can attach a polarizer or ND filter without a bulky holder system.
