Ultimate large-diameter,
    wide-angle zoom lens optimized
    for full-frame mirrorless cameras
    −“The definitive lens
    for astrophotography”
    with astonishing resolution.

    Many photographers like to use low sensitivity shooting to minimize noise as much as they can. Particularly in the photography of starry skies, bright wide-angle lenses are often selected because they can efficiently collect weak light. The 14-24mm F2.8 DG DN | Art has been developed as the ultimate large-diameter, wide-angle zoom lens by optimizing the standard specifications for photographing starry skies for full-frame mirrorless cameras. The uniform rendering performance and outstanding resolution to the edge of the frame make it the “definitive lens for astrophotography.” By utilizing the characteristics of the short flange focal length, this new-generation large-diameter zoom lens combines both compact body and unprecedented high-resolution image quality.

    About Product Name:
    Product name includes “DG” when the lens is designed to deliver the ultimate in performance on cameras with full-frame sensors, and “DN” when the lens design is optimized for mirrorless cameras with the short flange focal length.


    Newly developed
    high-performance lens series
    for full-frame mirrorless cameras

    With mirrorless cameras emerging at an accelerated pace, expectations towards lenses suited for high-performance full-frame mirrorless cameras are growing. Unfortunately, many photographers may feel that they have little choices for mirrorless lens systems in terms of performance, size, extensive lineup, and due to the burden of having to use multiple systems. SIGMA has thus developed and proposes this new full-frame mirrorless lens series as the optimal solution to this challenge.

    SIGMA will develop interchangeable lenses with unprecedented specifications and performance by designs that benefit from the short flange focal length feature of mirrorless cameras while retaining the concepts of “Contemporary,” “Art,” and “Sports.” We will announce three models as the first lenses from this series.

    image quality developed
    with exclusive low dispersion glass elements and NPC
    (Nano Porous Coating)

    One FLD glass and five SLD glass elements are appropriately arranged to suppress chromatic aberration to the edge of the frame. Three aspherical lenses, including a large-diameter aspherical lens at the foremost surface, are used to effectively minimize coma flare, etc., thereby achieving mind-blowing resolution.

    SIGMA’s unique coating technology Nano Porous Coating

    The super multi-layer coating is combined with SIGMA’s unique coating technology “NPC (Nano Porous Coating)”. The lens has been designed to be less susceptible to strong incident light such as backlight.
    “NPC (Nano Porous Coating)” incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.

    Substantial functions enable user confidence, even in tough environments

    Incorporating a stepping motor enables the high speed, quiet AF drive. Shooting is comfortable even in target AF such as Face/Eye Detection AF and during video shooting. The AFL button1 which can be assigned with various functions widens the range of operations available on the lens. Furthermore, the lens features a dust and splash resistant structure2, along with a water- and oil-repellent coating on the frontmost surface of the lens, which further supports shooting in various environments.

    2Dust and Splash Resistant Structure*2

    *1 Function available on supported cameras only. Available corrections may vary depending on the camera model.
    *2 Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.

    Rear filter holder as a standard accessory

    The lens comes with a rear filter holder equipped with a fall prevention lock for attaching sheet type rear filters for shooting starry skies.

    Other Features

    Designed to minimize flare and ghosting

    From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.

    Rounded diaphragm

    The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

    Compatible with Lens Aberration Correction

    Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

    rugged brass bayonet mount

    The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
