Sigma 12mm F1.4 DC
Unleash new creative perspectives with the Sigma 12mm F1.4 DC | Contemporary lens. This ultra-wide prime lens delivers exceptional optical performance even in the most demanding lighting conditions. It stands out as the widest F1.4 lens available for APS-C mirrorless systems today, making it a perfect choice for night skies, architectural interiors, travel, and immersive video work.
Despite its broad view and large aperture, Sigma has engineered a compact, lightweight form factor — at just 69.4 mm in length and 225 grams in weight. The optical design includes 14 elements in 12 groups, with 3 double-sided aspherical and 2 SLD glass elements to control aberrations and deliver crisp resolution across the frame.
With its stepping motor autofocus, the lens is tuned for smooth, quiet focus transitions — ideal for hybrid shooters who balance stills and video. Minimal focus breathing ensures your framing stays consistent during focus pulls in video. For rugged use, it features a dust- and splash-resistant mount and a water/oil-repellent coating on the front element, helping maintain clarity in challenging environments.
Whether you’re capturing stars, shooting interiors, or vlogging with dynamic perspectives, the Sigma 12mm F1.4 DC lets you see the bigger picture in stunning detail and true cinematic quality.
