Sigma has launched the 50-200mm F4-5.6 DC OS HSM telephoto zoom lens with optical stabiliser.

The lens features special low dispersion glass in the front lens group and an inner focusing system, as well as "Super Multi-Layer" coating to reduce flare and ghosting.

Hyper sonic motor technology makes for quick, quiet auto focusing, and the built-in optical stabilisation eliminates camera shake.

The lens has a minimum focusing distance of 110cm throughout the entire zoom range and a maximum magnification ratio is 1:4.5.

We'll get pricing and availability to you when we get it.
