Outstanding build quality /

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.

Professional feature-set /

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.

Effortlessly keep up with the action /

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.

High-performance optics /

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.

Perfect for portraits /

The lens’s F2.8 aperture produces a pleasing shallow depth-of-field effect and produces attractive smooth bokeh. In-focus details are exceptionally sharp thanks to the fast dual HLA motors and OS2 optical stabilisation algorithm.

Compatible with teleconverters /

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.

Made in Aizu /

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.

Water and oil repellent

A special coating applied to the front element to help repel water and oil.

Tripod foot

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.

Super multi-layer coating

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

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.

Full-frame lens

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.

Focus limiter

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.

Front filter thread

The lens has a filter thread around the front element onto which filters and filter holders can be attached.

Custom buttons

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.

Brass mount

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).

AF MF switch

This switch toggles between autofocus and manual focus.

9 rounded blades

The diaphragm is constructed of nine rounded blades for a circular aperture opening and round out-of-focus highlights.


Found on the barrel of some Sigma lenses, this button can be assigned to various functions to widen the range of operations available on the lens (available functions depend on the camera model).
Allows users to change aperture using the lens rather than the camera. The ‘Auto’ button on the ring switches aperture control to the camera.
Some lenses with an aperture ring have a click switch, which allows users to remove the ring’s clicking action. This means the aperture can be changed completely seamlessly rather than in stepped 1/3-stop increments. The function is ideal for film-makers.
This switch locks the aperture ring in either manual or auto, ensuring it can’t get knocked out of position when shooting.
One of the three lines of Global Vision lenses. The Art range includes a mixture of primes and zooms, which boast fast apertures, superb optics and exceptional build quality.
A type of lens element found in most Sigma lenses. Aspherical elements compensate for spherical aberration and distortion, which cannot be completely eliminated using conventional spherical lens elements alone. They are also key to reducing the size and weight of high-power zooms and other large lenses while improving image quality. Hybrid aspherical elements are made by bonding two elements together, one of which is glass and one of which is a polymer. Precision-molded glass aspherical elements are made by direct forming.
All Sigma lenses have a brass mount. It combines high precision with rugged construction and its treated surfaces and enhanced strength contribute to the long-term durability of the lens.
A light but strong material used on some Sigma lenses. It is also used in the interior and exterior fittings of aircraft, among many other applications.
Designed with size and weight in mind, these highly portable primes and zooms are designed for photographers who need to travel light, but without sacrificing image quality. Contemporary lenses typically don’t have such wide maximum apertures as Art lenses in order to keep their weight down, but do not compromise on optical performance. The I series range is part of the Contemporary line-up, sporting have an all-metal build and a manual aperture ring.
Designed for crop-sensor cameras. They can also be used on full-frame bodies, but only in crop mode.
Designed specifically for mirrorless cameras. Some non-DN lenses also fit mirrorless cameras, but these were designed originally for DSLRs and later adapted. DN lenses tend to be smaller and lighter.
This is found on some longer Sigma lenses, such as the 60-600mm F4.5-6.3 DG DN OS | Sports. It allows the user to zoom either by turning the zoom ring, which is very accurate, or by pushing and pulling the end of the lens, which is very fast. This makes the lens very adaptable to different types of fast-action subject.
A series of weather seals around the mount connection, manual focus ring, zoom ring and cover connection to keep out dust and water. 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.
The three-digit code printed on the surface of the lens is to indicate the year the lens was first released. 019, for example, denotes 2019.
A now near-defunct designation used to denote Sigma’s higher-end lenses. The only remaining current EX lens is the 105mm F2.8 EX DG OS HSM MACRO.
The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colours of light to focus at slightly different points. The result is chromatic aberration, the colour fringing that is particularly noticeable in telephoto lenses. ELD glass is a type of glass used in Sigma lenses with low dispersion qualities, which helps to keep chromatic aberration to a minimum.
The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colours of light to focus at slightly different points. The result is chromatic aberration, the colour fringing that is particularly noticeable in telephoto lenses. FLD glass is ultra-low-dispersion glass that offers performance of the highest level. Highly transparent, its refractive index and dispersion are extremely low as compared to conventional types of glass. It offers characteristics very similar to those of fluorite, which is valued for its anomalous dispersion. These characteristics minimise residual chromatic aberration (secondary spectrum), which cannot be corrected by ordinary optical glass, while helping to produce sharp, high-contrast images.
This system adjusts the distance between lens groups during focusing, thereby reducing the amount of lens movement required. The result is less aberration at different shooting distances.
This switch, found on selected 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. For example, when photographing zoo animals through a wire fence a photographer could set the focus limiter to, say, 10m–infinity, to stop the camera continually trying to focus on the fence, which is nearer to the camera than the subject. On some Sigma L-Mount lenses, the distances on the limiter can be customised via the USB Dock.
Allows user to toggle between focusing modes. On most Sigma lenses the options are AF and MF, but some lenses also have a Manual Override (MO) button, which allows manual focus by rotating the focus ring even during continuous AF.
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 and fast autofocus. The first lens to have an HLA motor was the 60-600mm F4.5-6.3 DG DN OS | Sports in early 2023.
Some Sigma lenses have a lockable lens hood to ensure they aren’t accidentally removed during use. Some work with a simple release button, while others have a screw action.
The Hyper Sonic Motor (HSM) is an original Sigma development that uses ultrasonic waves to drive the autofocus mechanism. It’s extremely quiet operation helps avoid disturbing photographic subjects. High torque and speed assure rapid autofocus response. Sigma uses two types of HSM: ring HSM and micro HSM. The Ring HSM configuration permits manual fine tuning of focus (Manual Override) by turning the focusing ring after autofocus is complete.
This sensor can detect the position of the focus lens with a high degree of precision by using a magnetic signal. This is done in real time to improve AF accuracy.
To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
Some Sigma lenses incorporate an Inner Zoom mechanism, meaning the barrel of the lens doesn’t change length when zooming in or out. This ensures the lens remains balanced, and since the front of the lens does not rotate, polarising filters can be used with extra convenience.
This is a stabilisation algorithm that enables photographers to pan more effectively. It uses information collected by an acceleration sensor to detect a panning movement (horizontal, vertical or diagonal) and deliver effective stabilization. This feature is available on all Sigma telephoto lenses that have OS switches 1 and 2 (with the exception of the SIGMA 120-300mm F2.8 DG OS HSM | Sports).
Based on 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. It is recommended to leave all corrections turned in the camera’s menu. Not available on all camera models.
This is a protruding lip built into the front of the lens to help keep a lens heater firmly in position. Lens heaters are used by astro photographers to prevent condensation forming on the front element.
Linear focusing simply means that the movement of the focus ring is consistent with the change to the focusing distance, regardless of how quickly the ring is rotated. This is common to all mechanical focusing systems. Non-linear focusing, which is found on Sigma’s mirrorless DN line of lenses, is an electronically controlled focus system where the sensitivity of the ring changes depending on how fast it is rotated. On some of Sigma’s DN lenses, users can switch between linear and non-linear focusing using the USB Dock, and also change the focus throw of the lens.
The magnification ratio of a lens describes the maximum size at which an object can be reproduced on the camera’s sensor. For example, if an object is 1cm long, and a lens can photograph it so that the impression on the sensor is also 1cm long, the magnification ratio is said to be 1:1. If the impression on the sensor were 0.5cm, the magnification ratio would be 1:2. Sigma’s macro lenses are true macro because they have a 1:1 magnification ratio.
The MFL switch disengages the focus ring on the lens. After manually focusing the lens to the desired position, users can set the MFL switch to ‘LOCK’ in order make the focus ring completely inactive. This prevents the focus of the lens from being moved by accident (such as when attaching a lens heater or changing the composition). The focus ring can still be rotated but will have no effect.
When Focus Mode switch is set to the MO position, the lens may be switched to manual focus simply by rotating the focus ring, even during continuous AF. The MO function is only available on some Sigma lenses.
An MTF chart helps show the optical performance of a lens. On the horizontal axis (x-axis) the figure represents the distance in mm from the centre of the lens. On the vertical axis (y-axis) the figure represents the transmission of light that travels through the lens, with 1 being 100% of the light (which is not possible on any lens). The higher this number, the better. At the centre of the lens (0 on the bottom axis), the transmission of light should be highest, and then it falls off slowly towards the edge. There are two types of MTF chart. One considers the diffraction quality of light, which is called ‘Diffraction MTF’. The other, ‘Geometrical MTF’, does not.
Sigma’s Nano Porous Coating is a lens coating that is designed to make a lens less susceptible to strong incident light, such as backlight. It uses porous silica, which has nano-sized holes containing air, as the coating material. 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, yielding clearer, higher contrast images.
SIGMA’s OS (Optical Stabilizer) function uses sensors inside the lens to detect motion, then moves specific lens elements in order to effectively minimise blur. Owing to the stabilised image in the viewfinder, it is possible to fine-tune composition and ensure accurate focusing.
A small number of Sigma wide angle lenses have a rear filter holder. This allows sheet-type filters, which are about the size of an SD card, to be inserted behind the rear element. Rear glass filters can be purchased, or filters can be cut from a special sheet using a guide plate as a template.
The polygonal shape of a conventional iris diaphragm causes out-of-focus points of light to appear polygonal. Rounded diaphragm blades are designed to make the aperture opening circular, producing circular out-of-focus highlights at wider apertures.
The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colours of light to focus at slightly different points. The result is chromatic aberration, the colour fringing that is particularly noticeable in telephoto lenses. SLD glass is a type of glass used in Sigma lenses with low dispersion qualities, which helps to keep chromatic aberration to a minimum.
Sigma’s Sports line of lenses is made up of telephoto primes and zooms designed for fast-action photography, such as wildlife, sports, motorsport and aviation. Sports lenses tend to have a wide range of features, superb image quality, weather sealing and very fast autofocus.
Lenses with a stepping motor are capable of smooth, quiet and high-speed AF, and are compatible with Face/Eye Detection AF and video AF.
SIGMA’s Super Multi-Layer Coating suppresses flare and ghosting by minimising reflections within the lens. All lenses in the current Sigma range feature this technology. On digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, the coating is highly effective, ensuring images with outstanding contrast.
An F stop, which is how the aperture value is expressed on a still lens, is measure by the size of the opening that lets through the light. On cine lenses, a T stop value is used instead, which also takes into account how much light is lost as it travels through the lens. This is why Sigma cine lenses have slightly different T stop values to the F stops values on the equivalent stills lenses.
Often called an extender, a teleconverter is a device that can be fitted to the rear of a lens to effectively increase its focal length. 1.4x converters increase focal length by 1.4 times, but at the cost of roughly one stop of light, and 2x converters increase focal length by 2 times but at the cost of roughly two stops of light.
Tripod socket Some longer Sigma lenses have a tripod socket attachment. Usually the socket is included with the lens, except on the 100-400mm F5-6.3 DG DN OS | C, on which it can be purchased separately. Some tripod feet have an Arca Swiss type shape, so can be attached straight on to a compatible tripod. The purpose of a tripod foot is to ensure the lens is properly balanced on a tripod. Without one, a tripod plate would need to be attached to the camera, which when used with a long, heavy lens, would place a great deal of strain on the lens and camera mount.
TSC is a type of polycarbonate with a thermal expansion rate similar to that of aluminium. This means that all parts that make up the lens barrel behave in a similar way as temperatures change, which ensures consistent results in all environments.
A special lens coating that allows water to be wiped away easily and prevents oils from sticking to the surface, even in challenging shooting conditions.
The Zoom Lock switch fixes the zoom ring at a specific focal length to help stop lens creep. Some lenses can only be locked at the widest focal length to keep the zoom locked during transportation, while others can be locked at two or more different focal lengths in the zoom range.
Introduced with the SIGMA 150-600mm F5-6.3 DG DN OS | Sports, the Zoom Torque switch changes the resistance of the zoom ring. At the ‘S’ setting, the ring has lower resistance and is easiest to turn. At the ‘T’ setting, the ring has greater resistance. At this setting lens creep is less likely. At the ‘L’ setting, the ring is locked in position.
