Samyang AF 12mm f/2.0 Ultra-Wide Prime Lens for Sony E-Mount APS-C, Weather-Sealed, Black

Most ultra-wide primes for APS-C force a compromise between speed, size, and weather resistance. The Samyang AF 12mm f/2.0 for Sony E-mount breaks that pattern: a compact, sealed barrel with a bright f/2.0 aperture and a 99.1° field of view. It delivers an 18mm full-frame equivalent perspective without the bulk, making it a natural fit for landscape, architecture, vlogging, and astrophotography.

Highlights

• Ultra-wide 12mm focal length on APS-C (18mm full-frame equivalent)
• Bright f/2.0 maximum aperture for low-light shooting and shallow depth of field
• Advanced optical design with 3 ED and 2 aspherical elements for sharp, high-contrast images
• Linear Stepping Motor (LSM) for fast, quiet, and accurate autofocus
• Weather-sealed construction for reliable use in challenging conditions
• Compact and lightweight design, ideal for travel and everyday carry

In daily use

Expansive interiors, sweeping landscapes, and immersive street scenes all benefit from the 99.1° angle of view. The f/2.0 aperture keeps ISO low in dim environments, while the 0.19 m minimum focus distance enables dramatic wide-angle close-ups with pleasing background blur. Autofocus is smooth and responsive, making it easy to track moving subjects or grab a quick shot without fuss. A 62mm front filter thread accepts standard ND and polarizing filters.
