Versatile Standard-Range Zoom. The Sigma 18-50mm f/2.8 DC DN Contemporary’s build is compact and lightweight. It weighs just over 0.5 lb. and takes 55mm filters. The 27-75mm equivalent zoom range, constant f/2.8 maximum aperture, and rounded seven-blade diaphragm make it great for portraiture, landscapes, architectural photography, event photography, and street photography.
High-Quality Optics. As a part of Sigma’s Contemporary lens line, the 18-50mm f/2.8 goes through rigorous testing to ensure high image quality. Its ten-group/thirteen-element optical design features one Special Low-Dispersion element and three aspherical elements that correct for chromatic aberrations and color fringing while ensuring high image sharpness, clarity, and contrast throughout the zoom range. A Super Multi-Layer coating minimizes lens flare and ghosting, helping to provide high contrast even in strong lighting.
Fast, Quiet Autofocus System. The 18-50mm’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. You get a 4.8-inch minimum focusing distance with a 1:2.8 maximum magnification, letting you take macro-style close-up shots.
