SIGMA 28-70mm f/2.8 DG DN Contemporary for Sony E
Smart and agile. The new standard mirrorless zoom.
SIGMA sets a new standard in Large-aperture mirrorless zoom lenses
The SIGMA 28-70mm F2.8 DG DN Contemporary model redefines the standard zoom for mirrorless cameras by combining excellent optical performance, a constant F2.8 aperture, and a lightweight, compact body. The design builds on the existing 24-70mm F2.8 DG DN Art model, but with a focal range starting at 28mm, making the lens body significantly smaller and lighter, while maintaining excellent optical performance. It is the smallest and lightest lens in its class*.
Staying true to the Contemporary line's core concept of maintaining an optimal balance between optical performance and lens size, this optic delivers professional-quality results in a body small enough for a casual ride. In addition to prioritizing portability, SIGMA's optical engineers have 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 have been employed to ensure an exceptionally high build quality. The 28-70mm F2.8 DG DN | Contemporary introduces another fast, high-performance large-aperture zoom lens to SIGMA's mirrorless lineup, offering a more compact alternative to the existing 24-70mm F2.8 DG DN | Arte.

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 model, which is known for its excellent optical performance throughout its zoom range. True to the core concept of the Contemporary lineup, the 28-70mm F2.8 DG DN Contemporary has been developed to deliver the right balance between performance and portability, and as such, this large-aperture standard zoom offers exceptional image quality that rivals Art lenses in a body that's light enough for everyday use. Based on cutting-edge technology, the 28-70mm F2.8 DG DN Contemporary has an advanced optical design that includes three aspherical elements, two FLD and two SLD. Despite using fewer elements in total than the 24-70mm F2.8 DG DN| Art, the design results in a complete correction of axial chromatic aberration and sagittal coma aberration, which cannot be corrected in-camera, allowing users to create uniformly sharp images 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 has a water- and oil-repellent coating on the front of the lens. In short, the SIGMA 28-70mm F2.8 DG DN | Contemporary combines all the key optical features required of a standard large-aperture zoom lens, which are essential for shooting a wide variety of subjects in a variety of shooting conditions.
A lightweight and compact body - Ideal for everyday use
Being slightly less wide-angle than the 24-70mm F2.8 DG DN allowed for a significant reduction in size from the 28-70mm F2.8 DG DN | Contemporary lens body. To fit 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. This makes it the smallest and lightest lens in its class*.
The new lens has only one light focus element, which keeps the AF unit small. This, along with a fast and quiet stepping motor, contributes to a responsive and near-silent autofocus performance. The 28-70mm F2.8 DG DN | Contemporary weighs 470g, and when connected to the SIGMA fp, the entire configuration is 890g. The supreme portability afforded by a camera system that weighs less than 1kg gives photographers a great deal of freedom and flexibility to achieve their creative vision.
It's also a perfect match for filmmakers looking for a high-performance, lightweight, and easy-to-handle camera system that works well with a gimbal and other accessories. A standard large-aperture zoom lens that's light and small enough for casual outings, the 28-70mm F2.8 DG DN | Contemporary will open up new photographic possibilities for better, more creative results.

Excellent build quality with exceptional attention to detail they provide An exceptional user experience
With a priority given to optimal portability, the body of the SIGMA 28-70mm F2.8 DG DN Contemporary consists mainly of lightweight parts. While conventional wisdom states that it is more difficult to ensure processing accuracy for plastic parts than for metal parts, there has not been any compromise in build quality for the 28-70mm F2.8 DG DN Contemporary. One reason for this is that it uses a type of polycarbonate called TSC (Thermally Stable Composite), which has a level of thermal contraction comparable to aluminum. This helps to reduce the differences between the thermal contraction of 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 your operation less premium, What allows us to achieve these precision-produced parts and premium aesthetics is the impressive standard of manufacturing technology and strict quality control that we have at the SIGMA Aizu Factory.
The SIGMA 28-70mm F2.8 DG DN Contemporary model offers a new and improved photography experience for mirrorless users who need a fast aperture standard zoom lens. Its premium, intuitive construction makes it as exciting to use the lens as it is to see the incredible images it can produce, inspiring you to start reaching your creative potential.
