Its inner zoom mechanism minimizes center of gravity fluctuations throughout the entire zoom range, making it a versatile and easy-to-use tool for an unprecedented range of shooting situations.

• Extremely high optical performance

  The Sigma 300-600mm F4 DG OS | Sports features 28 lens elements in 21 groups, including 6 FLD and 1 SLD glass elements, anomalous dispersion glass, and high refractive index glass. Its optical design provides excellent correction of various optical aberrations, such as chromatic aberration, throughout the entire zoom range. Although a zoom lens, the Sigma 300-600mm F4 DG OS | Sports delivers the unparalleled optical performance of a prime lens.

• HLA-driven high-speed AF

  Despite its large aperture of F4, the Sigma 300-600mm F4 DG OS | Sports features a lightweight focus lens group thanks to the use of a high-thrust HLA (High-response Linear Actuator) motor, optimized optical power arrangement and state-of-the-art glass materials. The result is a high-speed autofocus functionality with outstanding accuracy.

• Powerful Optical Stabilization function driven by the OS2 algorithm

  The Sigma 300-600mm F4 DG OS | Sports delivers exceptional optical stabilization of 5.5 stops* at 600mm. Powered by Sigma’s sophisticated OS2 algorithm and featuring a drive unit with a specially designed actuator and high-precision sensor, this lens effortlessly meets the demands of a large-aperture ultra-telephoto.

  Additionally, photographers have the choice between two OS modes: Mode 1 is suitable for most still photography and video situations, while Mode 2 was specially designed for panning shots. Driven by Sigma’s Intelligent OS algorithm, this mode stabilizes the image during horizontal, vertical, or diagonal movements, regardless of the camera’s orientation, enabling photographers to capture moving subjects with professional precision.

  * Based on CIPA guidelines. (Measured at a focal length of 600mm with a 35mm full-frame camera)

• Combines high robustness and mobility

  The lens barrel is made of magnesium alloy for the main parts and the hood is made of carbon, achieving both high robustness and light weight. In addition, the optical design with the center of gravity toward the camera greatly improves the weight balance, which tends to be front-heavy.

• Thermal insulation paint for perfect lens performance

  The exterior of the lens body is coated with a thermal insulation paint that effectively suppresses heat absorption from sunlight. This prevents the lens from heating up, even during long outdoor shoots in sunny weather, such as nature or motorsports photography.

• New function ring adds extended functionality

  The Sigma 300-600mm F4 DG OS | Sports features a newly added function ring that further expands the options of the lens. The focus ring offers two different modes, selected via its setting switch:

  Focus Preset Mode:
  By turning the function ring to the left or right, the focus can be instantly shifted to a pre-registered focus position. This is useful when frequently shooting at a fixed focus position.

  Power Focus Mode:
  Focusing at a constant speed is possible by operating the function ring. This allows for smooth focus shift during movie shooting as well as for focusing with minimal movement when shooting hand-held. Focusing speed can be changed in two steps depending on the angle at which the function ring is operated.

• Durable and easy-to-handle tripod socket

  The tripod socket's rotating mechanism uses bearings for both high durability and smooth rotation with an optional click/declick mechanism for each 90° angle to assist in accuracy. The tripod socket foot is compatible with Arca-Swiss type clamps, but can be easily removed and replaced with different interchangeable tripod sockets (available separately) to suit a variety of situations and preferences.

• Equipped with a drop-in filter holder

  The Sigma 300-600mm F4 DG OS | Sports features a drop-in filter holder for standard ø40.5mm filters. In addition, Sigma has developed a new drop-in circular polarizing filter and a variable ND filter (available separately) that can be adjusted by approximately 7-stops while dropped into the lens.

• Weatherability of Sigma’s Sports line specifications

  The mount joints, manual focus ring, zoom ring, custom switches and other control switches, and exterior joints are all protected from dust and splash by a dust- and splash-resistant structure*. Further, the frontmost surface of the lens is coated with a water- and oil-repellent coating to facilitate maintenance when water droplets or dust adhere to the lens.

  * The structure is designed to be dust- and splash-resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.

• Various functions to support shooting

  The lens features a variety of buttons and switches to accommodate individual preferences and the demands of different shooting situations, including AFL buttons in four different locations, a focus mode switch, a focus limiter switch, an OS mode switch (Mode 1 or Mode 2), and a custom mode switch. The L-Mount version of the lens is also compatible with Tele Converters (TC-1411/TC-2011) for AF-enabled shooting at a maximum focal length of 1,200mm.

• HLA (High-response Linear Actuator)

  HLA is Sigma's proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.

• Inner focus system

  To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

• OS2

  OS2 is the newly developed optical stabilizer algorithm. Compared to the previous algorithm used by Sigma lenses, OS2 improves the effect of optical stabilization significantly.

• Inner Zoom

  The lens incorporates an inner zoom. With their unchanging barrel length, these lenses also enhance balance and stability for the photographer. Furthermore, since the front of the lens does not rotate, polarizing filters can be used with extra convenience.

• 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.

• Water and oil repellent coating

  Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.

• AFL button

  the AFL button can be assigned with various functions widens the range of operations available on the lens.

• Focus Mode Switch

  Using this swich, it is possible to switch the focus mode between AF and MF.

• Focus Limiter

  Offers customization for the driving range of auto focus. It makes it possible to limit the drive range from a specific distance to a long distance or a short distance.

• Dust and Splash Resistant Structure

  This lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.

  *Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.

• Linear focus / Non-linear focus (for L-Mount only）

  A focus movement method of interchangeable lenses for mirrorless cameras (DN lens) in relation to the rotational angle of the focus ring during manual focusing.
  With "non-linear focus," the amount of focal point movement varies depending on the focus ring rotational speed.
  With linear focus, if the focus ring rotational angle is the same, the amount of focal point movement remains the same regardless of the focus ring rotational speed.

• Super Multi-Layer Coating

  Sigma's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma's Super Multi-Layer Coating is highly ef fective, assuring images of outstanding contrast.

• 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.

  *Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
  *On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON'(AUTO).

• Rounded diaphragm

  The polygonal shape of a conventional iris diaphragm causes out-of-focus light points to appear polygonal. A rounded diaphragm is designed to produce rounded out-of-focus light points when opened to near maximum aperture. This creates attractive bokeh effects in many situations, such as when photographing a subject against an out-of-focus surface of water from which light is being reflected.

• 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.
