History

    Durable high performance,
    redesigned with
    the photographer in mind

    Superior performance redesigned
    to meet photographers needs.
    A broader world of photography.
    A deeper level of expression.
    Thanks to the high-performance telephoto zoom
    that feels right in every situation.

    A professional 300mm F2.8 telephoto with powerful zoom capability, this lens allows complete customization, so you can tackle tough situations
    with ease.

    Offering excellent image expression and a low F-number, the large-aperture 300mm F2.8 lens is a favorite piece of equipment among professional photographers. With the idea of taking this spec to the next level with powerful zoom capability, SIGMA developed the 120-300mm F2.8 zoom lens. It is difficult to compose shots with traditional 300mm lenses. In the case of sporting events, performances on stage and other situations in which it is difficult to change your position, you often lose the desired shot in the process of changing lenses. A large-aperture 120-300mm F2.8 zoom lens, however, eliminates the need for most lens changes, allowing the photographer to adjust zoom and easily achieve the desired framing. Even in the most difficult of situations, this lens truly empowers photographic expression.

    Embodying the concept of our Sports line of lenses, this lens responds directly to photographers' needs with outstanding action-capture performance.

    In addition to the highest levels of optical performance and photographic expression, SIGMA’s new Sports line of lenses offers the kind of action-capture performance that precisely executes the intentions of the photographer. Uncompromising optical performance and photographic expression allow the photographer to shoot fast-moving and distant subjects, while exceptional functionality makes possible excellent shots even in the most challenging of situations. The SIGMA 120-300mm F2.8 DG OS HSM|Sports is the first lens to embody the concept of the Sports line. Fully customizable, it allows the photographer to create his or own specification. It is an ideal choice for photographing many different subjects; birds, wild animals, airplanes, motorsports, and even portraits. And SIGMA’s exclusive software makes the lens extremely easy to customize.

    Features

    Enhanced usability in every way

    Take the photo you want -
    even in the most challenging situations.
    Enjoy the highest levels of durability and usability.

    This lens features durability that stands up to challenging photographic situations and hard use demands along with the intuitive and enjoyable usability that photographers need. Since the lens uses SIGMA’s inner focus and inner zoom technologies, adjusting the focus and zoom rings does not change the length of the lens, resulting in excellent hold for the selected ring positions. Since the front of the lens does not move, the lens is compatible with a circular polarizer. In every way, SIGMA has designed the lens for exceptional usability. The zoom ring is textured to allow fingers to find the correct position easily. Designed for seamless integration with the rest of the lens, the four control switches feature carefully placed lettering and buttons and specially shaped screws. The lens hood has also been completely redesigned, even down to the screws that connect it to the lens, and the newly designed tripod collar provides for connection to a camera strap.

    HSM (hypersonic motor)

    HSM (hypersonic motor) delivers high AF speed and extremely quiet performance. An enhanced algorithm offers even smoother automatic focusing, and full-time manual focus override is another key feature.

    A refined, integrated design made with
    the photographer in mind.

    All lenses in SIGMA’s new Sports line come with a hood with a high-quality rubberized connector and feature a newly designed lens cap and AF/MF switch, and are designed for intuitive use and superior functionality. Inside, HSM (hypersonic motor) delivers high AF speed and extremely quiet performance. An enhanced algorithm offers even smoother automatic focusing. Full-time manual focus override is another key feature that leaves the artistic touches in the photographer’s hands.

    A powerful tool for handheld photography of distant subjects Optical Stabilizer

    This lens features SIGMA’s proprietary OS (Optical Stabilizer) offering superior stabilization. Thanks to this technology, the lens is a powerful ally to photographers shooting distant subjects without a tripod. Two OS modes are available: Mode 1 for regular photography, and Mode 2 for use in shooting motorsports and other situations in which subjects are moving quickly. By connecting the lens to the separately sold USB dock, users may adjust OS function in detail.

    Note: This function is not available with film SLR cameras with the exception of the Nikon F6 and Canon EOS-1v.

    Optical Stabilizer ON

    Optical Stabilizer OFF

    Specially designed cam for smooth zooming

    The specially designed cam makes possible smooth and rhythmical zooming, allowing photographers to find the right focus instantly and shoot with perfect timing.

    High-precision,
    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.

    TSC(Thermally Stable Composite)

    Conventionally it is considered essential to leverage the qualities of metal and polycarbonate in camera and lens layout design. A first for the industry, the barrel of the new series of SIGMA lenses features a new TSC (Thermally Stable Composite) that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens.

    Rounded diaphragm

    When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect – even at large-aperture settings.

    Compatible with the newly developed tele converters.

    Tele Converters that are newly designed to match the new lens line-ups (optional) can be attached. The addition of SIGMA’s TELE CONVERTER TC-1401 or TELE CONVERTER TC-2001 produces a 168-420mm F4 AF telephoto zoom lens or a 240-600mm F5.6 AF telephoto zoom lens respectively.

    SIGMA 120-300mm F2.8 DG OS HSM|Sports equipped with the firmware version 1.0.1 for SIGMA, version 1.0.2 for NIKON, version 1.0.3 for CANON or later is fully compatible with the SIGMA TELE CONVERTER TC-1401 and SIGMA TELE CONVERTER TC-2001. You can confirm or update the firmware version using the SIGMA USB DOCK. Otherwise, please refer to our World Network of service centers.

    Designed for exceptional resistance to dust and water

    Ready for the toughest photographic conditions,
    this extremely durable lens gives you peace of mind - and results.

    This lens is ready for all the tough situations that pros encounter. The mount connection area, manual focus ring, customization switch and other controls, switch panels and cover connection areas are all designed to be dust and water-resistant. The zoom and focus rings are also designed for exceptional usability in real-world circumstances.

    Rivaling a fixed-focal length lens
    in image quality

    Featuring F2.8 brightness and rivaling a fixed-focal length lens in image quality
    throughout the entire zoom range

    Offering excellent image expression and a low F-number, the large-aperture 300 mm F2.8 lens is a favorite piece of equipment among professional photographers. While taking this spec to the next level with powerful zoom capability, SIGMA has also used two lens elements made of fluorite-equivalent FLD (“F” Low Dispersion) glass and one element made of SLD (Special Low Dispersion) glass, which help minimize chromatic aberration and provide image quality that rivals that of a fixed-focus lens.

    F2.8 brightness throughout the entire zoom range

    This lens incorporates two FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, and one SLD (Special Low Dispersion) glass element to minimize chromatic aberration. Since it also minimizes sagittal coma flare and coma at the edges of the image, it is able to rival a fixed-focus lens in image quality.

    • FLD glass
    • SLD glass

    Flare and ghosting reduction

    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.

    Exclusive low-dispersion glass

    The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain.To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.
