Sigma 16-28mm f/2.8 DG DN Contemporary Lens (L-Mount)

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 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.
