Sigma 18-250 mm lens : The Sigma Corporation is pleased to announce the launch of new SIGMA 18-250mm F3.5-6.3 DC OS HSM lens for Sigma, Nikon, Canon, Sony and Pentax digital SLR cameras. The SIGMA 18-250mm F3.5-6.3 DC OS HSM lens incorporates Sigma’s original anti-shake compensation function, with a 13.8 times zoom ratio. As opposed to having an anti-shake function in the camera body, this lens’s Hybrid Optical Stabilizer provides not only an anti-shake function for the camera body, but also compensates for image shaking in the view finder as the Optical Stabilizer is built in to the lens.|

The new Sigma 18-250mm lens incorporates four Special Low Dispersion glass elements and three aspherical lens elements that provides excellent image quality throughout the entire zoom range. This Sigma 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. Incorporating super multi layer coating reduce the ghost in the backlight photography.
