Design based on SIGMA’s Art line, with the same uncompromising optical performance
The optical design of the SIGMA 28-70mm F2.8 DG DN | Contemporary is based on the 24-70mm F2.8 DG DN | Art, which is renowned for its outstanding optical performance throughout its zoom range. True to the Contemporary line’s core concept, the 28-70mm F2.8 DG DN | Contemporary was developed to offer the right balance of performance and portability, and as such, this large-aperture standard zoom delivers outstanding image quality that rivals Art line lenses in a body light enough for day-to-day use. Building on state-of-the-art technology, the 28-70mm F2.8 DG DN | Contemporary has an advanced optical design that includes three aspherical, two FLD, and two SLD elements. Despite using fewer elements in total than the 24-70mm F2.8 DG DN | Art, the design results in a thorough correction of axial chromatic aberration and sagittal coma aberration, which cannot be corrected in-camera, allowing users to create images that are uniformly sharp from the center to the edges of the frame. Along with its anti-ghosting design, the use of Super Multi-Layer Coating and Nano Porous Coating means well-controlled flare for high-contrast results in backlit conditions. It also features a water and oil repellant coating on the front side of the lens. In short, the SIGMA 28-70mm F2.8 DG DN | Contemporary combines all of the key optical features required of a large-aperture standard zoom lens, which are essential for photographing a wide variety of subjects in a range of shooting conditions.
