Sigma 28-70mm F2.8 DG DN Contemporary Lens – L-Mount Fit

The Sigma 28-70mm F2.8 DG DN Contemporary for L-Mount is a full-frame standard zoom lens with a constant f/2.8 maximum aperture, covering wide-angle to portrait-length focal lengths. Its optical design of 16 elements in 12 groups includes two FLD elements, two SLD elements, and three aspherical elements for sharpness and correction of aberrations, while Super Multi-Layer and Nano Porous coatings reduce flare and ghosting. Weighing 470g and taking 67mm filters, it is among the smallest and lightest lenses in its class, with a stepping motor providing fast, quiet autofocus and a rounded nine-blade diaphragm for smooth bokeh. It features dust- and splash-resistant construction and can be used on APS-C bodies with a 42-105mm equivalent focal length.
