Versatile Standard 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.
Dock Compatible. This lens is compatible with the Sigma USB Dock for Leica Lenses (separate rental item), allowing you to adjust the focus limiter, autofocus speed, microfocus, and OS settings through the Sigma Optimization Pro software.
