Sigma AF 70-200mm f2.8 DG DN OS I Sports lens for Sony FE 

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.

• Full-Frame | f/2.8 to f/22
• Fast Telephoto Zoom
• High-Response Linear Actuator AF System
• Optical Stabiliser with OS2 Algorithm
• Internal Zoom and Focus
• Minimised Focus Breathing
• Dust- and Splash-Resistant Construction

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.

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.

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.

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.

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 (only on compatible cameras. Available functions may vary depending on the camera used) 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.

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.

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.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their 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.
