Product Description

Amazon.com

Sigma's 28-105mm f3.8-f5.6 aspherical macro lens has an impressively flexible shooting range of 28-105mm. This lens is ideal for nature photographers wanting close-ups of plants and animals, yet equally suited for those who prefer landscapes, portraits, and snapshots.

Though containing some of its predecessors' strengths, such as a 19.7-inch close-focus range, this model gives you the slightly larger maximum aperture of f3.8-f5.6 and a lighter weight. The use of aspherical optics and a new mechanical construction in the design can be credited with the reduction in weight. Despite its compact size, just under three inches, this lens maintains the high level of performance for which its predecessors are known. The internal focusing system allows for a nonrotating front barrel, making for the convenient use of filters. This model is dedicated to Pentax AF SLR cameras.
