Sigma announces the new SIGMA 18-250mm F3.5-6.3 DC OS HSM lens. Due to be released on March 9, 2009 – the new SIGMA 18-250mm F3.5-6.3 DC OS HSM has Sigma’s original anti-shake function, having a 13.8X 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 back-light photography.
