Sigma 16-28mm f/2.8 DG DN Contemporary Sony E-mount lens

The Sigma 16-28mm f/2.8 DG DN Contemporary lens, specifically designed for Sony E-mount full-frame mirrorless cameras, delivers excellent optical performance in a compact size. This ultra-wide-angle lens offers a constant maximum aperture of f/2.8 throughout the zoom range, making it ideal for low-light photography and creating a beautiful, blurred background. With a minimum focusing distance of just 25 centimetres and nine rounded aperture blades, the lens produces attractive bokeh effects and clear, high-contrast images.

The optical construction consists of 16 lens elements in 11 groups, including five 'F' low-dispersion and four aspherical elements to minimise chromatic aberration, distortion, and spherical aberration. The Super Multi-Layer Coating reduces ghosting and flares for improved colour reproduction and clarity. Fast, smooth, and silent autofocus, made possible by a stepping motor and internal focusing mechanism, also makes this lens highly suitable for videography. The mount is dust and splash-proof, contributing to durability under various conditions.
