Sigma 28-300mm f/3.5-6.3 AF ASP IF Lens for Sigma SA MountModel: 427794
Lightweight and compact design, a full-fledged zoom lens with expanded distance capabilities and a 28-300mm zoom range; built for Sigma SA-mount bodies.
Using a triple-cam Internal-Focus (IF) system, this lens achieves a zoom ratio of 10.7:1, providing full coverage of a wide range of shots from panoramic views to close-ups-all in one lens. This lens can capture widely varying subjects, and you can rely on it when the decisive moment arrives. A compact design with a length of only 3.5 in (90mm) gives the lens even greater mobility. And SLD (Special Low Dispersion) glass and aspherical lenses give it high optical ability. The lens also has an inner focus system that allows it to be focused without having to turn the front of the lens and it accepts a Petal-type hood and circular polarizing filter.
Sigma's lens technology has produced a high performance zoom lens that is compact, lightweight and delivers high-quality images. This lens uses an SLD (Special Low Dispersion) glass in the optimum place in the lens groups for excellent correction of chromatic aberration; and, added two aspherical lenses for effective correction of spherical aberration and coma aberration. So the lens displays high optical ability throughout the entire zoom range.
