The Sigma 28-70mm f/2.8 DG DN | Contemporary redefines the standard zoom for mirrorless cameras by combining outstanding optical performance, an f/2.8 constant aperture, and a lightweight and compact body. The design of the 28-70mm f/2.8 DG DN | Contemporary is based on the existing 24-70mm f/2.8 DG DN | Art, but with a focal range starting at 28mm, making the lens body significantly smaller and lighter while maintaining superb optical performance. It is the smallest and lightest lens in its class. Remaining true to the Contemporary line's core concept of maintaining an optimal balance between optical performance and lens size, this new optic delivers professional quality results in a body small enough to take on a casual outing. In addition to prioritizing portability, Sigma’s optical engineers introduced a new combination of coatings and structural elements that make this standard zoom well-equipped for use in a wide range of shooting environments. Likewise, the latest production and manufacturing techniques were employed to ensure exceptionally high build quality. The 28-70mm f/2.8 DG DN | Contemporary introduces another fast, high-performance, large-aperture zoom lens to Sigma’s mirrorless line-up, offering a more compact alternative to the existing 24-70mm f/2.8 DG DN | Art.

Design Based on Sigma’s Art Line

The optical design of the SIGMA 28-70mm f/2.8 DG DN | Contemporary is based on the 24-70mm f/2.8 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 f/2.8 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 f/2.8 Lens 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 f/2.8 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 f/2.8 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.

Lightweight and Compact Body

Being slightly less wide-angle than the 24-70mm f/2.8 DG DN | Art has allowed a significant reduction in the size of the 28-70mm f/2.8 DG DN | Contemporary lens body. In order to fit with the design concept of the Contemporary line, which balances performance with portability, the new lens features a simpler dust- and splash-proof structure and smaller switches. The new lens features just one lightweight focusing element, which keeps the AF unit small. This, along with a quiet and fast stepping motor, makes for responsive and near-silent autofocus performance. The 28-70mm f/2.8 DG DN | Contemporary weighs in at 470g, and when attached to the SIGMA fp, the entire setup is 890g. It’s also a perfect combination for filmmakers looking for a high-performance, lightweight, easy-to-handle camera system that works well with a gimbal and other accessories. A large-aperture, standard zoom lens that is light and small enough for casual outings, the 28-70mm f/2.8 DG DN | Contemporary will open up new photographic possibilities for better and more creative results.
