Sigma Contemporary 18-50mm f/2.8 DC DN
A constant f/2.8 aperture across the 18-50mm zoom range is packed into a weather-sealed body weighing just 290g, making it exceptionally portable for APS-C mirrorless systems. Its stepping motor delivers fast, quiet autofocus and the 4.8-inch minimum focus distance enables 1:2.8 magnification macro-style close-ups. This lens is best for travel photographers and hybrid shooters who need a lightweight, versatile standard zoom without sacrificing low-light capability.
