Sigma has said that its 18-250mm F3.6-6.3 DC OS HSM superzoom lens is now available in mounts for Sony and Pentax SLRs. This lens incorporates a Hybrid Optical Stabilisation system, which can be used on bodies which have built-in anti-shake (the camera's stabiliser must however be switched off). It also has a hypersonic motor for fast and quiet autofocus, and a minimum focus distance of 45cm for close-up photography. The MSRP is $800 in the USA, and £559.99 in the UK.
