This is an ideal DG lens for Digital SLR cameras.

This large-aperture wide-angle lens is capable of Macro photography. Its fast f/1.8 maximum aperture provides high performance at all shooting distances down to its minimum focusing distance of 7.1". A reproduction ratio of 1:2.7 and an angle of view of 84.1 degrees allow you to capture high quality images not only of a subject but also the surrounding scenery. Also, the iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus images in the foreground and background.

Sigma's advanced optical construction utilizes a floating focus system and two aspherical lens elements for superior peripheral brightness and compensation of aberrations and astigmatism. Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras. The Dual-Focus (DF) mechanism eliminates the need for the front of the lens to rotate during auto-focus. The wide, textured, rubberized focus ring conveniently moves forward to click into AF position and back to select manual focusing.
