The first of the series is the standard lens 30mm F1.4 DC DN | Contemporary, and the second is the wide-angle lens 16mm F1.4 DC DN | Contemporary. The third addition is this smallest mid-tele lens in its class, 56mm F1.4 DC DN | Contemporary. While retaining the compact, lightweight, and outstanding image quality concepts of the Contemporary line, thanks to SIGMA’s leading-edge technology, this lens provides the amount of bokeh and admirable brightness expected from F1.4 lenses even in the mid-tele range. This addition completes the large aperture series comprised of portable wide-angle, standard, and telephoto lenses.
