The 18-50mm f/2.8 DC DN Contemporary Lens from Sigma is a small, light, and bright standard zoom for crop-sensor mirrorless cameras. Offered here with a FUJIFILM X-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. An ultimate workhorse, the lens features a minimum focusing distance of just 4.8", enabling it to be used for macro-style close-up photography, and the lens is also outfitted with a rounded seven-blade diaphragm for a pleasing bokeh quality. Constant f/2.8 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth-of-field techniques. Special Low Dispersion (SLD) element reduces chromatic aberrations and color fringing. In-camera aberration correction further eliminates optical imperfections such as distortion and vignetting. A minimum focusing distance of 4.8" and a 1:2.8 maximum magnification ratio benefit working with close-up subjects.
