Sigma has announced the new 70-200mm F2.8 DG DN OS | Sports lens, for full-frame L-mount and Sony E-mount systems. The lens completes Sigma’s full-frame mirrorless f/2.8 trio, alongside the 14-24mm and 24-70mm models, and is aimed at sports, wildlife, wedding and live-event photographers.

The new lens combines two dual HLA (High-response Linear Actuator) motors and Sigma’s OS2 optical stabilisation algorithm, which enables it to deliver fast, accurate and near-silent autofocus even for challenging fast-action subjects, the company claims.

An optical stabiliser function with the OS2 algorithm provides up to 7.5 stops of effective stabilisation, allowing for shake-free hand-held images in low-light environments. The Sigma 70-200mm F2.8 DG DN OS | Sports lens also includes de-clickable aperture ring so clicks don’t intrude when you are recording video, plus a built-in Arca Swiss-compatible tripod socket, a focus limiter and weather-sealing.

In addition, the new lens comes with six FLD (F Low Dispersion) and two SLD (Special Low Dispersion) elements, while three aspherical glass elements reduce spherical aberration. It also includes a 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 and accurate autofocus when shooting sports, wildlife and aviation, or capturing fleeting moments at weddings and events.

Compact design is another selling point of the Sigma 70-200mm F2.8 DG DN OS | Sports. Weighing in at 1,345g (L-mount specification) the new lens is significantly smaller and lighter than the existing 70-200mm F2.8 DG OS HSM Sports for DSLRs. This has been achieved by using CFRP (carbon fibre reinforced plastic) and TSC (Thermally Stable Composite) materials for the lens and hood.
