The perspective that changes with the angle-of-view gives picture an extraordinary feeling.Delicate compositions can be adjusted by lens zooming and this is helpful for close-up photography. Provides deep depth of field with its short focal length for amazing photographic expressions.This ultra-wide zoom lens covers a large wide-angle range from 15 mm to 30 mm. With a minimum focusing distance of 30 cm(11.8 inches) throughout the entire zoom range, it is an ideal lens for Digital SLR Cameras.It incorporates hybrid aspherical lens in the front lens group to minimize distortion and astigmatism, and molded glass aspherical lens in the rear lens group to minimize spherical aberration. Minimization of the distortion is a most important issue for zoom lens, but Sigma has succeeded, to provide image quality with minimal distortion by employing aspherical lenses.This lens incorporates an internal focusing system, which eliminates front lens rotation. Since focusing do not change its overall length, this lens is easy to hold and use. Also it is allowing the use of a Petal-type Hood.The lens also incorporates Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens.
