The world’s first1 lens to achieve a 12mm focal length with a large F1.4 aperture. The ultra-wide angle of 12mm (equivalent to 18mm,2 in 35mm format) captures the entire scene in front of you, while the dynamic angle of view and brightness of F1.4 enable highly impressive photography even in low-light conditions, such as nighttime street photography. Additionally, the ultra-wide angle is ideal for group selfies and vlogging. Whether shooting stills or video, the Sigma 12mm F1.4 DC | Contemporary offers high flexibility and diverse possibilities in creative expression.

High-speed, high-precision autofocus is achieved by driving a lightweight focus lens with a stepping motor that enables precise control. Whether shooting still images or videos, the Sigma 12mm F1.4 DC | Contemporary captures important moments without missing a beat. In addition to everyday snapshots, the lens delivers high tracking performance in scenes with movement, enabling high-quality video production.

Minimal focus breathing

Focus breathing is suppressed, minimizing changes in the angle of view caused by focus shift and enabling smooth, natural-looking focus pulls when recording video.

Equipped with an aperture ring for intuitive control of the aperture. The Canon RF Mount version has a control ring instead of an aperture ring, allowing functions to be assigned according to the user’s preferred settings.

Using advanced simulation technology, flare and ghosting have been largely eliminated, ensuring that the lens renders rich, high-contrast results in all conditions.

In addition to a dust- and splash-resistant structure1, the frontmost surface of the lens has a water- and oil-repellent coating applied, so that the lens can be used safely even in harsh outdoor environments.
