Strong visual expression through outstanding optical performance in a combination of ultra-wide-angle and F1.4 aperture

The 12mm focal length delivers the widest angle of view among F1.4 lenses for APS-C cameras.
The world's first*1 Lens with a focal length of 12mm and a large F1.4 aperture. The very wide angle of view of the 12mm (equivalent to 18mm*2 in 35mm format) captures the entire scene in front of the camera. This dynamic angle of view combined with the F1.4 aperture enables impressive shots even in low light conditions, such as street photography at night. The ultra-wide angle is also perfect for creative group selfies and is ideal for vlogging. Whether photos or videos, the Sigma 12mm F1.4 DC | Contemporary offers high flexibility and a wide range of possibilities for creative expression.

Outstanding optical performance across the entire image
Three double-sided aspherical lenses and two SLD glass elements contribute to the high optical performance of the Sigma 12mm F1.4 DC | Contemporary from aperture F1.4. Sagittal coma is also well corrected, which ensures clear, sharp images from edge to edge. This makes the Lens particularly suitable for astrophotography - stars are still depicted in a pinpoint shape even close to the edge of the image.

Compact and lightweight design for excellent mobility
The effective arrangement of the double-sided aspherical elements also contribute to the compact and lightweight design. For an ultra-wide angle lens with a large aperture, it has an overall length of just 69.4mm and weighs only 225g*. This ensures a high degree of mobility, so that the Sigma 12mm F1.4 DC | Contemporary can easily be taken on trips and for a wide range of shots. It is also easy to use with shooting grips and gimbals. Photographers and filmmakers can effortlessly enjoy the creatively dynamic expression that only a 12mm F1.4 lens can offer.

Designed for comfortable shooting of photos and videos

Smooth, responsive autofocus through stepping motorr
The fast, high-precision autofocus is achieved by driving a lightweight focus lens via a stepping motor, which enables accurate control. Whether taking photos or videos, the Sigma 12mm F1.4 DC | Contemporary captures important moments without missing anything. The Lens is not only suitable for everyday snapshots, but also offers high tracking performance in moving scenes, enabling high-quality video productions.

Minimal focus-breathing
Focus-breathing has been suppressed extremely effectively in the Sigma 12mm F1.4 DC | Contemporary. This virtually eliminates changes in the angle of view when moving the point of focus, which ensures very natural-looking focus tracking when shooting video.

Functional aperture ring
The Sigma 12mm F1.4 DC | Contemporary is 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, which can be assigned individual functions via the camera menu of compatible cameras.

Optical design to minimize flares and ghosting
Flares and ghosting have been largely eliminated thanks to state-of-the-art simulation technology of all light incidence situations during the development phase of the Sigma 12mm F1.4 DC | Contemporary. As a result, the lens delivers high-contrast results under all conditions.

Dust protection, splashprotection* and water and oil-repellent coating
In addition to the dust and splash-protected construction, the front element of the Sigma 12mm F1.4 DC | Contemporary has a water and oil-repellent coating. This means that the lens can also be used in harsh conditions.
* The lens is dust and splash-proof, but not waterproof. Make sure that the Lens does not come into complete contact with water. Water inside a lens can cause major damage and even make it irreparable.

Extends the range of F1.4 lenses for APS-C mirrorless cameras

The Sigma Contemporary range already offers a wide selection of F1.4 lenses for APS-C cameras. Based on the concept of combining exceptional resolution with a compact, lightweight design, Sigma has developed a complete range of F1.4 lenses of the most important focal lengths - 16mm, 23mm 30mm and 56mm, and now also 12mm. The Sigma 12mm F1.4 DC | Contemporary further expands the series of fast Lens. This series offers outstanding optical performance while being perfectly suited for the compact mirrorless APS-C systems.
