The Sigma 16-28mm f/2.8 DG DN Lens L-Mountis 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 on optical quality. A fast f/2.8 constant aperture allows for the use of faster shutter speeds in low-light scenarios as well as being especially useful for closeup shots thanks to its shallow depth of field.

This lens utilizes a complex arrangement of specialized aspherical and low dispersion glass elements to effectively 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.
