Sigma 14mm f/1.4 DG DN Art Lens for Leica L

The Sigma 14mm f/1.4 DG DN Art Lens for Leica L is a full-frame, ultra-wide prime lens ideal for landscape photography. 

It features a wide aperture of f/1.4, which allows you to use a faster shutter speed in low light conditions. This is especially beneficial during astrophotography as well as closeup images, as it creates a shallow depth of field and beautifully soft bokeh effects.

This Sigma 14mm DG DN Art lens makes use of a complicated setup that consists of 19 lens elements divided into 15 groups and it includes 1 SLD, 3 FLD and 4 aspherical lens elements to reduce and eliminate aberrations like sagittal coma flare and enhance clarity. It also contains a super multicoating to reduce ghosting and flare in bright lighting conditions, leaving you with improved contrast and accurate colour rendering.

  • Full-Frame | f/1.4 to f/16
  • Designed for Astrophotography
  • HLA Autofocus Motor
  • TS-141 Tripod Socket
  • Rounded 11-Blade Diaphragm
  • Dust and Splash-proof Design

Designed to benefit photographers in various photographic scenarios from landscapes and astrophotography to pin sharp portraits.

Sigma 14mm f/1.4 DG DN Art Lens for Leica L

New vision. Expanding possibilities.

The world's first and only* lens that combines an ultra-wide angle of 14mm with a maximum aperture of f/1.4.

All for the best starscape 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 f/1.4 DG DN | Art is the world’s widest f/1.4 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 f/1.4. In addition, SIGMA’s lens technology has achieved high optical performance with thorough correction of sagittal coma flare, specialised functions to support starry landscape photography, and high-speed AF with an 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 a pictorial image that surpasses the actual photographic experience. Its proven ability in shooting star-scapes will provide new possibilities for visual expression and enjoyment in all scenes, including daytime landscapes, architecture, and indoor photography in dark and confined spaces.

*Excluding fisheye lenses, as interchangeable lenses for mirrorless cameras and SLR cameras (as of June 2023 by SIGMA).

Ultra wide-angle 14mm with a maximum aperture of f/1.4 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 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. Optimised for star scapes, which require extremely high performance, this lens delivers images that exceed expectations in any scene, including landscapes, architecture snapshots, portraits, and indoor photography.

Abundant functions and accessories to support star-scape photography

The 14mm f/1.4 DG DN | Art is equipped with a wealth of features to support starscape photography. This fully backs up the fun of starscape photography.

Tripod Socket

Includes a detachable tripod socket compatible with Arca-Swiss type. As the 14mm f/1.4 DG DN | Art is heavier on the front side, attaching the tripod socket helps it mount on a tripod in a more stable way. The shape is designed to prevent interference even when using the lens heater.

MFL (Manual Focus Lock) Switch

A switch to lock the manual focus at a desired position. Prevents focus shift caused by unintentional operation of the focus ring. This is useful for long-time exposure photography, etc., where the focus should be fixed.

Lens Heater Retainer

A lip at the front of the lens prevents the lens heater* from protruding into the front of the lens and causing vignetting on the periphery of the screen.

*A belt-shaped heater that is wrapped around the lens to prevent condensation from forming inside the lens when the temperature drops.

*Lens heater is not included.

Rear filter Holder

A rear filter holder is provided as standard equipment at the lens mount for attaching a sheet-type rear filter. A lock mechanism is also provided to prevent the filter from falling out.

Special front cap with locking mechanism and filter slots

Includes a cover-type front cap with a locking mechanism. It also has newly developed filter slots that can hold two rear filters depending on the application. The cap is specially designed for the 14mm f/1.4 DG DN | Art to protect the sheet filters from scratches and dirt while ensuring that they are not mistakenly taken out or forgotten.

Signature Art line features and high-build quality

In addition to functions specifically designed for shooting star-scapes, the lens is equipped with various functions to assist in shooting, including an AFL button to which any function can be assigned and an aperture ring. The body is dust and splash resistant, and the frontmost surface of the lens is coated with a water and oil-repellent coating, so you can shoot outdoors in harsh environments with peace of mind. The HLA (High-response Linear Actuator) enables high-speed, quiet, and highly accurate autofocusing. In order to maintain performance while supporting a lens with a large aperture, the lens has a robust internal structure and uses lightweight materials such as polycarbonate TSC (Thermally Stable Composite), which has a thermal shrinkage rate equivalent to that of aluminium, and magnesium in appropriate locations to reduce weight while ensuring robustness. The lens body is built with the high build quality of the Art line specifications, allowing the user to fully enjoy the unique performance of the lens in any environment, including shooting star-scapes.
