Compact High Performance Zoom Lens with 10.7:1 Zoom Ratio
Using our own triple-cam Internal-Focus (IF) system, we achieved 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 monument 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.
It has a length of 3.5 in. (90mm) and a filter size of 67mm. We used a 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. Moreover, the technology we used in this lens has a significant contribution to compact-design.
A 10.7:1 zoom ratio means you can always rely on this lens when the decisive moment arrives.
Using our own triple-cam internal focus system, we achieved a high zoom ratio of 10.7:1 with a focal length range from 28mm wide angle to 300mm telephoto. This means that you can capture widely varying subjects without having to change lenses, so you won't miss out when the decisive moment arrives. The lens is also portable, making it ideal for travel photography. In fact, it covers a wide range of subject situations from landscape photography to snap photography on the street. In addition, this lens re-defines high performance, giving you a high degree of flexibility in selecting picture composition and the power to express exactly what you want.
Inner focus system allows use of Petal-type hood.
The inner focus system allows the lens to be focused without having to turn the front of the lens, and facilitates the use of a circular polarizing filter. It also allows the lens to accept a Petal-type hood, with its superior light-blocking effect.
Equipped with convenient function that make the lens easy to carry and easy to use.
The zoom lock switch function prevents the lens from creeping due to its own weight, and avoids the danger of shock when the lens is being carried. The maximum photography magnification scale corresponding to each focusing distance and focal length is display on the barrel.
