Featuring a magnesium alloy body, thermal insulation paint and a number of additional features such as the newly added function ring, the Sigma 300-600mm F4 DG OS | Sports has been designed to support professionals achieve their best shots.

Exceptional versatility in the ultra-telephoto range
The Sigma 300-600mm F4 DG OS | Sports extends the capabilities of a 600mm F4 prime lens with the freedom to zoom out all the way to 300mm without compromising optical performance. 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.

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 Degree 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 40.5mm 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.

Weather ability of Sigma's Sports line
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 front most 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.

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 switch, 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.

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.
