Sigma has announced a new ‘large aperture’ 17-70mm macro lens aimed at digital SLR users.

The 17-70mm f/2.8-4 DC Macro OS HSM includes Optical Stabiliser, technology claimed to enable photographers to use shutter speeds around four times slower than would otherwise be possible.

Features include a minimum focusing distance of 22cm and a maximum magnification ratio of 1:2.7, making it ideal for close-up photography, according to Sigma.

Also on board the 520g newcomer are three aspherical lenses and one ELD (Extraordinary Low Dispersion) glass element.

The lens is available in Sigma, Canon, Nikon (D), Pentax and Sony (D) mounts, priced £399.99.

Sigma points out that vignetting will occur if the lens is used with 35mm film-based SLRs or digital cameras with image sensors larger than ‘APS-C’ size.
