The Sigma 16-28mm f/2.8 DG DN Contemporary Lens is a compact, high-performance ultrawide zoom meant to compliment a photographer's arsenal by providing a versatile range of focal lengths in a small and lightweight package, without compromising optical quality. A fast f/2.8 constant aperture allows for faster shutter speeds in low-light scenarios and is especially useful for close-up shots thanks to its shallow depth of field.

This lens utilizes a complex arrangement of specialized aspherical and low-dispersion glass elements to suppress chromatic aberrations for improved clarity and color accuracy. Super Multi-Layer and Nano Porous Coatings have also been applied to improve contrast and color rendering by reducing lens flare and ghosting when working in strong lighting conditions. The inner zoom & focus mechanism keeps the dimensions of the lens constant throughout the zoom range and at all focus distances. This design feature allows for almost no balance point shift and a fixed front element, making it an ideal instrument for videography, travel, and landscape photography.
