Sigma 18-50mm F2.8 DC DN | Contemporary (Sony E)

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 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. Together they minimize the total number of elements for superb optical quality without excessive weight. Autofocus is exceptionally fast and quiet thanks to the lens's stepping motor, which can be particularly useful when shooting video or fast-moving subjects such as children and animals. The standard zoom lens is designed for APS-C-format Sony E-mount cameras and provides a 27-75mm equivalent focal length range. Three high-precision glass-molded aspherical elements are used to help limit distortion and spherical aberrations and contribute to greater overall sharpness and accurate rendering. Super Multi-Layer Coating minimizes flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions. A stepping motor with nearly silent autofocus makes it perfectly suited to a range of photographic applications, including shooting in quiet environments, recording videos, and capturing fast-moving subjects. The rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
