Sigam 120-300mmSigma has debuted its revamped 120-300mm f/2.8 telephoto lens, first announced at the Photokina show last year.

Aimed primarily at sports and wildlife photographers, the Sigma APO 120-300mm f/2.8 EX DG OS HSM is due out in a Nikon fit later this month.

Commenting on the Canon version, which went on sale a couple of weeks ago, a Sigma Imaging UK spokesman revealed that they are hard to come by as ?demand is outstripping supply?.

The lens, priced £2,499.99, carries an Optical Stabilisation system claimed to enable use of shutter speeds around four stops slower than would otherwise be possible.

The newcomer also includes ?weather-resistant? sealing connections designed to stop dust and water entering the camera body.

An SLD element and two FLD glass elements aim to minimise chromatic aberration.
