The Sigma AF 70-200mm F2.8 DG DN OS I Sports lens is the perfect combination of performance and portability. It features a bright F2.8 maximum aperture and optical stabilization, offering consistently sharp images and 4 Stop Vibration Reduction. With a dust and splash-proof construction, this lens is perfect for outdoor photography.

Keep up with the action with fast and accurate AF

The SIGMA 70-200mm F2.8 DG DN OS Sports has been developed with both photography enthusiasts and professionals in mind. By utilising a combination of two dual HLA (High-response Linear Actuator) motors and Sigma’s OS2 optical stabilisation algorithm, the lens is able to deliver fast, accurate and near-silent autofocus even for the most challenging fast-action subjects.

Professional performance throughout the entire zoom range

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.

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.

Designed to minimise focus breathing, flare and ghosting

The lens has 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.

Internal zoom mechanism

With the implementation of an internal zoom mechanism, the lens is can be used on a on a gimble as weight shift during zooming is minimal.

Weather resistant design

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.
