Sigma announces the new 14mm f/1.4 DG DN | Art lens. This is the world’s widest f/1.4 single focal length lens (excluding fisheye lenses), designed specifically for astrophotography. The 14mm f/1.4 DG DN | Art lens is a full-frame, ultra wide-angle prime designed exclusively for mirrorless camera systems and is available in Sony E- mount and Leica L-Mount.

This lens offers a full set of features designed for astrophotography, including a removable tripod socket, MFL switch (Manual Focus Lock function), lens heater retainer, rear filter holder, and a specially-designed front cap including a new locking mechanism and new filter storage slots. All this, plus thorough aberration correction, make this possibly the best lens ever made for astrophotography. Its ultra-wide 14mm angle of view that captures wide starry skies and bright f/1.4 aperture that minimizes exposure time are ideal specifications for astrophotography. Incredibly sharp from corner to corner with a splash and dust-resistant construction, this lens retains the same high performance and quality standards as the Sigma f/1.4 Art lineup.

The astrophotography-focused feature set and total optical performance make this an excellent lens for high-end architecture, real estate, landscape, and street photography as well.

The stars in the sky are a source of inspiration for viewers. On the other hand, the starry sky is a demanding subject for a wide-angle lens, with its numerous tiny point light sources spread over the entire image. Thanks to Sigma’s latest technology, the lens combines an ultra-wide angle of 14mm with a maximum aperture of f/1.4. 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 the HLA (High-response Linear Actuator) linear motor.

The Milky Way stretching across the night sky, twinkling stars emerging over ridgelines –the 14mm f/1.4 DG DN | Art can make this a reality as an 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.

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 f/1.4 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 requiring extremely high performance, this lens delivers images that exceed expectations in any scene, including landscapes, architecture snapshots, portraits, indoor, and street photography.
