The definition of versatility, the 24-105mm f/4 DG OS HSM from Sigma is an Art-series zoom covering a useful wide-angle to short-telephoto range. Featuring a constant f/4 maximum aperture, this lens strikes an ideal balance between a portable form factor along with a bright enough design for working in available lighting conditions. Complementing this design, an Optical Stabilizer helps to minimize the appearance of camera shake throughout the zoom range for sharper handheld shooting. A Hyper Sonic Motor also contributes to intuitive handling and provides especially fast and quiet autofocus performance along with full-time manual focus override.
Complementing the physical design, this lens is also distinguished by its advanced optical layout, which include a series of low dispersion elements and three aspherical elements. These specialized elements reduce chromatic and spherical aberrations throughout the zoom range in order to realize a high degree of sharpness and clarity. Additionally, a Super Multi-Layer Coating has also been applied to individual elements to suppress lens flare and ghosting for improved contrast and color rendering in strong lighting conditions.
