Design based on SIGMA’s Art line lenses, with the same uncompromising optical performance

The optical design of the SIGMA 28-70mm F2.8 DG DN Lens | 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 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 | C 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 | A, 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 centre to the edges of the frame. Along with its anti-ghosting design, the use of Super Multi-Layer Coating and NanoPorous Coating means well-controlled flare for high-contrast results in backlit conditions. It also features a water and oil-repellent 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.

With the addition of the new 28-70mm F2.8 DG DN | C, SIGMA now offers two high-performance, F2.8, standard zoom options for mirrorless cameras. This new lens offers the same professional optical performance as the existing 24-70mm F2.8 DG DN | C, but it comes in at 365g lighter (figures for L-Mount version) so has the added benefit of being exceptionally portable.

Sigma 28-70mm F2.8 DG DN Lens is a lightweight and compact body perfect for day-to-day use

Being slightly less wide-angle than the 24-70mm F2.8 DG DN | Art has allowed a significant reduction in the size of the body of the 28-70mm F2.8 DG DN | Contemporary. In order to fit with the design concept of the Contemporary line, which balances performance with portability, the new lens features simpler dust- and splash-proof structure and smaller switches. This makes it the smallest and lightest lens in its class*. The 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 F2.8 DG DN | C weighs in at 470g, and when attached to the SIGMA fp, the entire setup is 890g. The supreme portability afforded by a camera system that weighs less than 1kg gives photographers a huge amount of freedom and flexibility to achieve their creative vision. It’s also a perfect combination for film-makers looking for a high-performance, lightweight, easy-to-handle camera system that works well with a gimbal and other accessories. This large-aperture, standard zoom that is light and small enough for casual outings will open up new photographic possibilities for better and more creative results.

Superb build quality with exceptional attention to detail for an exceptional user experience

With priority given to optimal portability, the body of the SIGMA 28-70mm F2.8 DG DN | C consists primarily of lightweight parts. While conventional wisdom states that it is more difficult to ensure processing accuracy for plastic parts than metal parts, there has been no compromise whatsoever with the build quality of this lens. One reason for this is that it uses a type of polycarbonate called TSC (Thermal Stable Composite), which has a comparable level of thermal shrinkage to aluminium. This helps reduce differences between the thermal shrinkage of the metal and non-metal parts, ensuring stable levels of performance even in an environment with extreme temperature changes. The use of polycarbonates in the construction of zoom and focus rings can make their operation feel less premium, but with careful treatment to the precision of these parts and in the lubricant technology that has been employed, the rings offer a precise action with an exceptionally high-quality feel.

What allows us to achieve these precisely produced parts and such premium aesthetics is the impressive standard of manufacturing technology and rigorous quality control we have at the SIGMA Aizu Factory.

The SIGMA 28-70mm F2.8 DG DN | Contemporary offers a new and improved photographic experience for mirrorless users needing a fast-aperture, standard zoom lens. Its premium, intuitive build makes it as exciting to use the lens as it is to see the incredible images it can produce, inspiring you to start achieving your creative potential.
