Shoot sports, wildlife, weddings and live events in stunning detail with the SIGMA 70-200mm F2.8 DG DN OS | Sports, designed exclusively for full-frame mirrorless cameras. Dual HLA (High-response Linear Actuator) motors deliver rapid, accurate and silent focusing that can handle even the most challenging of fast-action subjects. The built-in Optical Stabilizer function with OS2 algorithm provides up to 7.5 stops of effective stabilisation, allowing for shake-free hand-held images in low-light environments.
As well as being optically outstanding at all focal lengths and apertures, the lens includes a range of professional features, including a de-clickable aperture ring, a built-in Arca Swiss foot, a Focus Limiter and weather-sealing for superior protection in tough conditions. This complete feature-set, compact size and superb optical performance make the SIGMA 70-200mm F2.8 DG DN OS | Sports for L-Mount and Sony E-mount systems the definitive fast-aperture zoom for both enthusiasts and professionals.
Shoot in challenging weather conditions thanks to the lens’s weather-resistant design, which utilises rubber seals to keep out dust and moisture. The lens’s streamlined optical and mechanical design uses high-quality materials specially designed to resist changes in temperature and improve durability.
By using a streamlined internal design, the lens is significantly smaller and lighter than the existing SIGMA 70-200mm F2.8 DG OS HSM | Sports for DSLRs. The lens and hood are constructed using a multi-material structure consisting of CFRP (carbon fibre reinforced plastic) and TSC (Thermally Stable Composite) materials, resulting in a total weight of only 1,345g*
CFRP is a strong, lightweight material providing additional strength and resistance to damage, especially useful for heavy professional use. TSC has a thermal expansion rate similar to aluminium, ensuring consistent lens performance even whether shooting in the freezing temperatures of the Arctic to hot Saharan desert.
With the implementation of an internal zoom mechanism, the lens can be used on a on a gimble as weight shift during zooming is minimal.
The lens mount, focus ring, zoom ring and switches are dust and splash resistant* to prevent dust and dirt from entering the lens. The front element of the lens is also protected with an oil- and water-repellent coating, making it easy to clean and prevent water smears.
*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.

Take control of the depth-of-field using the built-in aperture control ring, the first to be featured on a SIGMA Sports lens. Set the ring to F2.8 to create beautiful separation between the subject and background with pleasing bokeh. The ring can be de-clicked, which is useful for film-makers, and locked so that it cannot accidentally be knocked from an auto to manual aperture setting, or vice versa.
The lens is equipped with a Focus Limiter switch that limits the focus driving range. This is especially helpful where subjects are a constant distance away and when shooting through dense environments. The three AFL buttons* found around the lens barrel can be set to a preferred camera function for easier handling. L-Mount users can customise the lens further by using a SIGMA UD-11 USB Dock to change how the OS operation works or fine-tune the Focus Limiter range.
* Only on compatible cameras. Available functions may vary depending on the camera used.
The SIGMA 70-200mm F2.8 DG DN OS | Sports features a unique floating focus system. Two focusing groups, each using an HLA motor, move in opposite directions when focusing. This reduces internal movements by half, providing fast, accurate and near-silent AF when shooting fast-paced subjects such as sports, wildlife and aviation, or fleeting moments at weddings and events.
Shooting handheld in low light situations has never been easier, thanks to the use of the exclusive OS2 optical stabilisation algorithm, which provides an incredible 7.5-stop advantage at 70mm and a 5.5 stop-advantage at 200mm*. The lens also features two OS modes. Mode 1 can be used for all types of photography. Mode 2 employs SIGMA’s Intelligent OS algorithm for smoother panning shots. Regardless of the lens’s orientation, the stabilisation is effective for both vertical and diagonal movement and doesn’t interfere with the panning motion.
Designed using ultra-high-performance low-dispersion glass, which includes six FLD and two SLD elements, the SIGMA 70-200mm F2.8 DG DN OS | Sports delivers outstanding image quality throughout the entire zoom range, even wide open at F2.8. Three aspherical glass elements further improve optical performance by reducing spherical aberration. Distortion and vignetting are extremely minimal and chromatic aberration is very well controlled even in high contrast areas.
The lens has also been designed to suppress focus breathing, meaning that the change in angle-of-view when focusing is minimised. This ensures a natural-looking focus shift when recording video. Highly backlit shooting environments are no trouble thanks to the use of advanced technology simulations and high-quality glass elements that keep flare and ghosting to a minimum.
The 70-200mm DG DN OS | Sports lens is ideal for both enthusiast and professionals and is often paired with the 14-24mm F2.8 DG DN and 24-70mm F2.8 DG DN, creating a trio of high-performance lenses with unbroken focal range of 14-200mm and a consistent F2.8 aperture. Photographers who are looking for a slightly longer and lighter focal length can consider the 100-400mm F5-6.3 DG DN OS. This lens is part of the Contemporary series designed for everyday use and portability. Two fantastic lenses to choose from depending on your personal requirements.
SIGMA has two teleconverters that are compatible with the L-Mount version of the lens. The TC-1411 1.4x converter (produces 84-840mm) and the TC-2001 2x converter (produces 120-1200mm). Both converters work with full AF.
All Sigma cameras and lenses are designed, manufactured and assembled at our sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
Sigma chose Aizu as its main production base in the early 1970s. Situated at the base of Mount Bandai in the Fukushima Prefecture, about four hours’ drive north of Tokyo, Aizu has an abundance of very clean water from mountain streams, which is essential for grinding and polishing lenses. Sigma’s founder, Michihiro Yamaki, was also drawn to this area for its workforce, who have a reputation for their craftsmanship, work ethic and attention to detail. Mr Yamaki’s son, Kazuto Yamaki, now the owner and CEO of SIGMA Corporation, has the same unwavering commitment to keeping production in Japan.
Today Sigma’s factory is more than 50,000 square feet in size, and packed full of some of the most advanced optical manufacturing technology in existence. So when you buy a Sigma camera or lens you can be sure that virtually every single component part has been manufactured and assembled by SIGMA, in Japan, with the greatest level of care and attention. We hope you enjoy using our products.
If you want to see how a particular SIGMA lens or camera performs, why not test drive it with our SIGMA Select hire service. Available for selected SIGMA lenses, short-term loans are free of charge (including shipping), with a small fee if you want to test it for longer. Refundable deposit required.

Mounting a camera with a heavy lens on a tripod puts huge strain on the camera’s tripod thread. To get around this some telephoto lenses have a tripod socket so that the camera and lens attach to the tripod at or close to their centre of gravity. This ensures a more balanced set-up.
This suppresses flare and ghosting by minimising reflections within the lens, ensuring punchy, high-contrast results. All lenses in the current Sigma range feature this technology.
Sigma’s Optical Stabilizer function uses sensors inside the lens to detect motion, then moves specific lens elements in order to effectively minimise blur. This helps ensure shake-free images at slower shutter speeds.
Internal focus or an inner focus system means the lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel. This helps keep the centre of gravity of the lens more constant when changing focus.
The lens has an image circle large enough to be used on a full-frame camera. It can also be used on cameras with a smaller ‘crop’ sensor, provided the mount is compatible.
This switch, found on some Sigma telephoto lenses, allows users to limit the focusing range to either near distance or far distance. This helps speed up AF, and also ensures the camera won’t attempt to focus on an unwanted area of the frame.
The lens has a filter thread around the front element onto which filters and filter holders can be attached.
This switch is found on selected Sigma lenses. On L-Mount versions it is possible to customise the OS and focus limiter distance and assign these to C1 or C2. On Sony E-mount C1 and C2 are pre-assigned to control the OS effect.
The mount is the part of the lens that attaches to the camera body. A coated brass mount is used for strength, and is surrounded by a rubber seal to keep out dust and moisture.
Found on the barrel of some Sigma lenses, the AFL button can be assigned to various functions to widen the range of operations available on the lens (available functions depend on the camera model).
This switch toggles between autofocus and manual focus.
The diaphragm is constructed of nine rounded blades for a circular aperture opening and round out-of-focus highlights.
