Independent lens maker Sigma has revamped two more of its lenses to add Hyper Sonic Motor (HSM) functionality for Nikon digital SLRs.
Priced £289.99, the Sigma 17-70mm f/2.8-4.5 DC Macro HSM has a maximum magnification of 1:2.3 and a minimum focus distance of 20cm.
A Special Low Dispersion (SLD) lens and two aspherical lenses aim to improve image quality.
Also revealed is the Sigma 18-55mm f/2.8 EX DC Macro HSM, boasting a maximum magnification of 1:3, SLD glass and Extraordinary Low Dispersion lens elements. It carries a £389.99 pricetag.
Earlier this month Sigma announced updated versions of its 18-50mm f/3.5-5.6 and 55-200mm f/4-5.6 zoom lenses, both with HSM, for use on Nikon SLRs (see below).
