 The new SIGMA 18-250mm F3.5-6.3 DC OS HSM is now available in Sony and Pentax mounts.This lens incorporates a Hybrid Optical Stabilisation system which allows photographers to us the lens’ OS function even if the camera has a built in anti-shake system. If the photographer chooses to use the lens’ OS function, they must ensure that the camera’s built in stabiliser is switched off. This lens has only been available in Sigma, Canon and Nikon fit for two months and has already won two international awards including the 2009 TIPA Best Entry Level Lens award. Four Special Low Dispersion glass elements and three aspherical lens elements provide excellent image quality throughout the entire zoom range. This lens has a minimum focusing distance of 45cm (17.7 inches) at all focal lengths and a maximum magnification ratio of 1: 3.4, making it ideal for close-up photography. The lens incorporates super multi-layer coating to reduce ghosting during backlight photography. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarising filters and the supplied petal-type hood. Highlights:
