The Sigma 28-70mm F/2.8 DG DN for Sony E-mount is a professional zoom lens in a compact body. Excellent optical performance combined with fast constant aperture.
The optical design is based on the 24-70mm F/2.8 DG DN from the Art series, but the lens is significantly smaller and lighter, without compromising performance. The design features three aspherical, two FLD, and two SLD lens elements. This corrects for axial chromatic aberrations and sagittal coma aberrations, for even edge-to-edge sharpness. In addition, Super Multi-Layer Coating and Nanon Porous ensure perfect flare control and contrast-rich images with backlighting. Finally, the front lens is equipped with a coating that repels water and oil to make it easy to clean.
The 28-70mm weighs just 470 grams, making it great to take anywhere. A lightweight focusing element is used to keep the autofocus unit compact. Combined with the extremely quiet and fast stepping motor, this results in responsive and near-silent autofocus performance. Following the design concept of the Contemporary line, the lens features a splash- and dust-proof structure on the mount and smaller switches. High-quality materials and techniques ensure that all components perform properly and continue to do so, even under extreme temperature fluctuations.
