Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E

The Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E offers versatility as a wide-angle to portrait-length zoom characterized by its f/2.8 maximum aperture. Suited for working in available lighting conditions, the bright design affords greater control over depth of field along with increased low-light performance. Compared to other 24-70mm lenses, it's lighter and more compact, perhaps making it the best choice for the filmmaker looking for a high-performance compact camera system that is easily handheld with a gimbal or other game-accessory attachments. I wrote that word easily and very intentionally. With just one light-focusing element inside and a fast and quiet stepping motor, the AF is near-silent and responsive with the Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E.

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.
