Sigma 18-50mm f/2.8 E-mount Lens

The Sigma 18-50mm f/2.8 DC DN Contemporary Lens is a small, light, and bright standard zoom for crop-sensor mirrorless cameras. Offered here with a Sony E-mount, this lens provides a versatile full-frame equivalent zoom range of 27-75mm and a wide constant aperture of f/2.8 throughout the entire zoom range. The lens design includes three high-precision glass-molded aspherical elements coupled with a special low dispersion element. Together they minimize the total number of elements for superb optical quality without excessive weight.
