With a maximum diameter of 70mm (2.75 in.) and a length of 75.2mm (2.96 in.), it is compact.Ideal for travel and snapshot photography, this lens uses Sigma’s own triple-cam internal focus system and achieves high performance in a compact package. This high magnification zoom lens covers focal lengths from 28mm wide angle to 200mm telephoto, with closeup capability.With two aspherical lenses, it has excellent correction for all types of aberration. It incorporates special internal focusing to enable it to focus as close as 48cm (18.9 inches) from film plane to subject, at all focal lengths. The aspherical lens contributes more than compact size: it also delivers improved image quality. The front lens group has excellent correction for distortion at the wide-angle setting, and the rear lens group effectively corrects for spherical aberration, coma aberration, and astigmatic aberration throughout the entire zoom range. This adds up to a lens with outstanding optical ability.Because of the inner focus system, the front barrel does not have to rotate to focus the lens, and a circular polarizing filter can be easily used. In addition, a Petal-type hood can be mounted on the lens to give optimum protection from flare.At the 200mm telephoto setting, the lens is capable of macro photography with a 1:3.8 maximum magnification. The minimum focusing distance is 48cm at all zoom settings. A magnification scale displayed on the lens barrel.A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight, and to avoid the danger of the lens receiving a shock while it is being carried.
