Fast-Aperture Wide-Angle Prime. The Sigma 23mm f/1.4 DC DN Contemporary’s build is compact and ultra-light. It weighs just over 0.7 lb. and takes 52mm filters. Its 35mm equivalent field of view and fast f/1.4 maximum aperture make it great for portraiture, close-up photography, and much more.
High-Quality Optical Design. As a part of Sigma’s Contemporary lens line, the 23mm f/1.4 goes through rigorous testing to ensure high image quality. Its ten-group/thirteen-element optical design features three Special Low-Dispersion elements and two aspherical elements that correct for chromatic aberrations and color fringing while ensuring high image sharpness, clarity, and contrast. A Super Multi-Layer coating minimizes lens flare and ghosting, helping to provide high contrast even in strong lighting.
Fast, Quiet Autofocus System. The 23mm’s integrated stepping autofocus motor provides fast, quiet operation in a broad range of shooting situations, and its optimized AF algorithm helps facilitate smooth performance. The 9.8-inch minimum focusing distance and 1:7.3 maximum magnification ratio let you get in close.
