Sigma 18-250mm F3.5-6.3 DC OS HSM

January 14, 2009: The Sigma Corporation is pleased to announce the launch of new SIGMA 18-250mm F3.5-6.3 DC OS HSM on March 10th, 2009.

The SIGMA 18-250mm F3.5-6.3 DC OS HSM 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.

Incorporating four Special Low Dispersion glass elements and three aspherical lens elements provides 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 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.
