Ultra wide-angle 14mm with a maximum aperture of F1.4
and outstanding optical performance



This world-first performance was achieved by applying the best of SIGMA’s optical technologies, from the design to the lens manufacturing process. 19 elements in 15 groups, including 1 SLD glass element, 3 FLD glass elements, and 4 aspherical lens elements, make up a luxurious lens configuration. This allows for advanced aberration correction and a high degree of precision in the lens construction. This allows both advanced aberration correction and F1.4 brightness. In particular, sagittal coma flare, which distorts the shape of stars, has been carefully corrected, and even at the widest aperture, the lens delivers high image reproducibility right to the periphery of the image. Ghosting and flare are also thoroughly addressed through both optical design and coatings. This allows for clear, crisp shooting of starry sky and night scenes. Optimized for starscapes, which require extremely high performance, this lens delivers images that exceed expectations in any scene, including landscapes, architecture snapshots, portraits, and indoor photography.

The stars in the sky are a source of inspiration for viewers. On the other hand, the starry sky is a very demanding subject for a wide-angle lens, with its numerous tiny point light sources spread over the entire image. The 14mm F1.4 DG DN | Art is the world’s widest F1.4 single focal length lens*, born from our engineers’ passion for capturing the widest, brightest, highest-resolution, and most captivating starry sky possible. Thanks to SIGMA’s latest technology, the lens combines an ultra-wide angle of 14mm with a maximum aperture of F1.4. In addition, SIGMA’s lens technology has achieved high optical performance with thorough correction of sagittal coma flare, specialized functions to support starry landscape photography, and high-speed AF with HLA (High-response Linear Actuator) linear motor.

The Milky Way stretching across the night sky, twinkling stars emerging over ridgelines―The 14mm F1.4 DG DN | Art can make this a reality as a pictorial image that surpasses the actual photographic experience. Its proven ability in shooting starscapes will provide new possibilities for visual expression and enjoyment in all scenes, including daytime landscapes, architecture, and indoor photography in dark and confined spaces.
