Uncompromising optical performance

Building on state-of-the-art technology, the Sigma 28-70mm F2.8 DG DN | Contemporary lens has an advanced optical design that includes three aspherical, two FLD, and two SLD elements. 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 Nano Porous 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 lens 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.

A lightweight and compact body - ideal for day-to-day use

Being slightly less wide-angle than the Sigma 24-70mm F2.8 DG DN | Art lens has allowed a significant reduction in the size of the 28-70mm F2.8 DG DN | Contemporary lens body. In order to fit with the design concept of the Contemporary line, which balances performance with portability, this lens features a 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 | Contemporary lens weighs in at 470g. The supreme portability gives photographers a huge amount of freedom and flexibility to achieve their creative vision. A large-aperture, standard zoom lens that is light and small enough for casual outings, the 28-70mm F2.8 DG DN | Contemporary will open up new photographic possibilities for better and more creative results.

Superb build quality with exceptional attention to detail

The SIGMA 28-70mm F2.8 DG DN | Contemporary lens consists primarily of lightweight parts. It uses a type of polycarbonate called TSC (Thermally Stable Composite), which has a comparable level of thermal shrinkage to aluminum. 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 adjusting the movement with the lubricant appropriately, the rings offer a precise action with an exceptionally high-quality feel.

The SIGMA 28-70mm F2.8 DG DN | Contemporary lens offers a new and improved photographic experience for mirrorless users who require 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.
