Sigma has unleashed a revamped version of its 18-200mm f/3.5-6.3 lens.

Priced £499.99, the18-200mm f/3.5-6.3 II DC OS HSM replaces the existing version launched four years ago.

Asked what improvements have been made, a Sigma Imaging UK spokesman told us: ?The new lens incorporates FLD glass which offers improved resolution and light transmission.

?The Optical Stabiliser has also been improved giving a four-stop benefit.

?The lens is also smaller, lighter and focuses closer [38cm].?

A Super Multi-Layer Coating reduces flare and ghosting, claims Sigma.

The new lens is available in Sigma, Nikon, Canon, Pentax and Sony DSLR mounts.
