The definition of versatility, the Sony A-mount 24-105mm f/4 DG 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, 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.
