Sigma 12mm F1.4 DC | Contemporary (For Sony E-Mount)

Sigma 12mm F1.4 DC | Contemporary (APS-C Ultra-Wide Prime) is a compact, ultra-wide prime lens built to unlock bold perspectives with outstanding image quality—perfect for landscapes, travel, street photography, astrophotography, vlogging, and cinematic APS-C video. Combining a 12mm ultra-wide angle with a bright F1.4 aperture, it delivers strong low-light performance and expressive depth, making everyday scenes look bigger, richer, and more dramatic. Sigma positions it as the widest 12mm option among F1.4 APS-C AF lenses, designed for creators who want maximum coverage without sacrificing speed. 

Built with an advanced optical design featuring aspherical and SLD elements, the lens achieves high resolution across the frame and helps control coma—ideal for clean, sharp stars and crisp edges in wide-open shooting. It’s also tuned for real-world lighting with design measures to reduce flare and ghosting, delivering contrasty, color-accurate results in challenging conditions. 

For hybrid shooters, a fast stepping motor AF provides smooth, responsive focusing for both stills and video, while minimal focus breathing helps keep framing stable during focus pulls. The lens is also travel-friendly: compact dimensions, lightweight build (weight varies by mount), and a durable design that includes a dust- and splash-resistant structure plus a water- and oil-repellent front coating for outdoor use.
