Sigmaâ€™s new 18-250mm F3.5-6.3 DC OS HSM is now available in Sony and Pentax mounts, priced at $800 US.
This lens incorporates a Hybrid Optical Stabilization system which allows photographers to use the lensâ€™ OS function even if the camera has a built in anti-shake system. If the photographer chooses to use the lensâ€™ OS function, they must ensure that the cameraâ€™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.
The new lens has a minimum focusing distance of 45cm (17.7 inches) at all focal lengths and a maximum magnification of 1:3.4 reproduction ratio, making it ideal for close-up photography. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters and the supplied petal-type hood.
