PMA 2007: Sigma Shows 18-200mm F3.5-6.3 DC OS Lens

Sigma 18-200mm F3.5-6.3 DC OS Lens

Sigma’s new 18-200mm F3.5-6.3 DC OS is a high zoom lens designed exclusively for use with digital SLRs. Sigma has equipped it with its own Optical Stabilizer (OS) technology which uses two sensors inside the lens to detect vertical and horizontal motion of the camera and works by moving an optical image stabilizing lens group, to effectively compensate for camera shake.

Sigma says the new zoom lens features two SLD (special low dispersion) glass elements and two aspherical lenses to provide excellent correction for all types of optical aberrations.

An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using circular polarizing filters and the supplied petal-type lens hood.
