Smooth, Responsive Autofocus Powered by a Stepping Motor

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.

Compact and Lightweight Design

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.

Designed to Minimise Flare and Ghosting

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

Dust and Splash-Resistant Structure / Water and Oil-Repellent Coating

In addition to a dust- and splash-resistant structure*, the front-most 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.

* The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers.
