Sigma today announced the release of the new SIGMA 120-300mm F2.8 DG OS HSM, the telephoto zoom lens that achieves superior performance redesigned to meet photographers’ needs. Conventionally, large aperture lenses for 300mm F2.8 have been loved by professional users due to their brilliant capability of depiction and bright aperture value. It has established a solid standpoint in the world of photography. Based on the concept that turning a 300mm F2.8 lens into zoom lens would enable photographers to expand the scope of shooting, Sigma have developed 120-300mm F2.8 lenses and released them into the market. It is not simple to decide on a composition with a 300mm lens. Especially for sports and theatrical shows, shooting positions are almost always fixed and changing lenses could lead to missed photographs.
HSM (hypersonic motor) delivers high AF speed and extremely quiet performance. An enhanced algorithm offers even smoother automatic focusing, and full-time manual focus override is another key feature. The lens is ready for all the tough situations that pros encounter. The mount connection area, manual focus ring, customization switch and other controls, switch panels and cover connection areas are all designed to be dust and water-resistant. The zoom and focus rings are also designed for exceptional usability in real-world circumstances.
Offering excellent image expression and a low F-number, the large-aperture 300 mm F2.8 lens is a favorite piece of equipment among professional photographers. While taking this spec to the next level with powerful zoom capability, Sigma has also used two lens elements made of fluorite-equivalent FLD (“F” Low Dispersion) glass and one element made of SLD (Special Low Dispersion) glass, which help minimize chromatic aberration and provide image quality that rivals that of a fixed-focus lens.
