Sigma L-Mount Alliance Lenses>28-70mm f/2.8 DG DN Contemporary Lens for L-Mount

A Versatile Zoom Lens for Leica L-Mount

The 28-70mm f/2.8 DG DN Contemporary Lens from Sigma is a great choice for Leica L-Mount users. This versatile wide-angle to portrait-length zoom is characterised by its constant maximum aperture of f/2.8, making it ideal for working in low light conditions. It’s also more lightweight and compact than similar 24-70mm lenses. The optical design incorporates two FLD and two SLD low-dispersion elements plus three aspherical elements, reducing aberrations to achieve high sharpness, clarity and colour accuracy. It features one lightweight focusing element, which keeps the AF unit small and quiet, making for fast and near-silent autofocus performance. This makes it perfect for filmmakers looking for a high-performance, lightweight and easy-to-handle camera system that works well with gimbals and other accessories.

Each optical surface features Super Multi-Layer and Nano Porous coatings to improve contrast and colour 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.
