Sigma 12mm f1.4 DC Contemporary Lens for Canon RF-S Mount

The Sigma 12mm f/1.4 DC Contemporary Lens is a compact, fast-focusing wide-angle prime designed for APS-C format Canon RF-S mount mirrorless cameras, offering an 18mm equivalent focal length that captures expansive views perfect for landscapes, city scenes, interiors, and vlogging. Its bright f/1.4 maximum aperture allows for smooth background blur and reliable performance in low-light conditions, while the stepping AF motor delivers quick, accurate autofocus with minimal focus breathing for both stills and video. The optical construction incorporates three double-sided aspherical elements that maintain sharpness while reducing distortion, as well as two special low dispersion elements that minimize chromatic aberrations and color fringing for improved clarity and fidelity. With 14 elements arranged in 12 groups, the design balances performance with portability. Weighing less than any other lens in Sigma's f/1.4 DC Contemporary series and measuring 20% shorter than the Sigma 16mm f/1.4 DC DN, this 12mm lens is an excellent choice for travel, handheld shooting, and everyday use. A rounded nine-blade diaphragm enhances the quality of out-of-focus areas, creating smooth, attractive bokeh. Built with a dust- and splash-resistant structure and front element coatings that repel water and oil, the lens maintains durability and ease of cleaning during outdoor use. A physical aperture ring allows quick adjustments, while a 62mm filter thread ensures broad compatibility with a variety of lens accessories, making this lens a versatile and practical option for creators seeking a balance of wide perspective, bright aperture, and lightweight design.
