• The widest angle of view of 12mm among F1.4 lenses for APS-C cameras

  The world’s first*1 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.

  *2. Equivalent to 19mm for Canon RF Mount.

• Outstanding optical performance across the entire image

  Three double-sided aspherical lenses and two SLD glass elements are effectively arranged to achieve high optical performance from a wide-open aperture of F1.4. Sagittal coma flare is also well corrected, ensuring clear, crisp images from edge to edge, even in starry night scenes where fine details and sharpness are essential.

• Compact and lightweight design for excellent portability

  The effective placement of double-sided aspherical elements has resulted in a compact and lightweight design with a total length of 69.4mm and a weight of 225g*1, despite its ultra-wide angle and large aperture.
  This ensures high mobility, making the lens easy to carry around for travel and outdoor scenes. The lens is also compatible with shooting grips and gimbals.
  Photographers and filmmakers can enjoy the dynamic expression unique to a 12mm F1.4 lens, effortlessly.

• 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.

• Aperture ring with various functions

  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 Designed to minimize flare and ghosting

• Designed to minimize 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*1 / water- and oil-repellent coating

  In addition to a dust- and splash-resistant structure*1 , 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.
