Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Leica L

The Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Leica L is a versatile wide-angle to portrait-length zoom offering a constant f/2.8 maximum aperture for working in low-light conditions and for enhancing control over depth of field. Although larger and heavier than a 24-70mm f/2.8, it weighs considerably less than other 24-70mm lenses, making it a good, light travel zoom. The Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Leica L optical design consists of two FLD and two SLD elements, as well as three aspherical elements, to control a variety of aberrations and deliver sharp, clear, and color-accurate imagery. Just one lightweight focusing element keeps the AF unit small, and its quie­­t and fast stepping motor allows for smooth, fast, and near-silent autofocus performance that suits both stills and video applications (ideal for filmmakers compiling a high-performance, lightweight, and easy-to-handle camera system that is useful with a gimbal or other accessories).

Each optical surface features Super Multi-Layer and Nano Porous coatings to improve contrast and color rendering by suppressing lens flare and ghosting for optimal light transmission, and an added water- and oil-repellent coating on the front optic helps keep the lens free from smudges and droplets. The weather-sealed design benefits working in trying environmental conditions, and a nine-blade rounded diaphragm contributes a pleasing bokeh quality when using wider apertures.
