SIGMA 16-28mm F2.8 DG DN | Contemporary

A perfect all-around lens for travel, architecture, candid street, and even nature photography, this wide-angle to standard zoom offers a fast constant maximum aperture so zooming does not sacrifice speed. Recognizing that modern lenses must handle both still and video capture equally well, SIGMA has designed the inner zoom and focus mechanism to maintain lens dimensions constant through both zoom range and varying focusing distances, something videographers will appreciate. In addition, a stepping motor benefits both still and video work with its fast and quiet AF performance. The 9-bladed diaphragm can make for beautiful bokeh effects in closeups while the f/22 minimum aperture and 25cm (9.9in.) close-focusing capability allows for composing often fascinating near to far subject relationships within the frame and maintaining sharpness throughout.
