    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.

    Comparison of the two optimal solutions to standard zoom lenses with F2.8 brightness throughout the zoom range

    With the addition of the new 28-70mm F2.8 DG DN | Contemporary, SIGMA now provides two optimal solutions of standard F2.8 zoom lens for mirrorless cameras - the new 28-70mm F2.8 DG DN | Contemporary achieves remarkable portability and offers the same optical performance, as the existing 24-70mm F2.8 DG DN | Art which is for pro-use with the highest levels of performance throughout its focal range.

    A lightweight and compact body - ideal 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 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, 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 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 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 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 F2.8 DN | Contemporary will open up new photographic possibilities for better and more creative results.

    Superb build quality with exceptional attention to detail that provides an exceptional user experience

    With priority given to optimal portability, the body of the SIGMA 28-70mm F2.8 DG DN | Contemporary 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 on 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 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. 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 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.

  • I hope the L-mount version has the option for linear focus response.

  • On March 23, Sigma Co., Ltd. announced that some of the lenses for the first shipment of the interchangeable lens "SIGMA 28-70mm F2.8 DG DN | Contemporary" for L and E mounts will have very bad ghost resistance due to aging.

    Lens is designed exclusively for mirrorless cameras and released on March 12th. While maintaining the optical performance of the "SIGMA 24-70mm F2.8 DG DN | Art" released prior to December 2019, the wide-angle side is 28mm, which makes it smaller and lighter (for L mount: 470g). The feature is that it was done.

    The lens for which the problem was confirmed is a product whose serial number is earlier than "55488834" regardless of the mount. Currently, the company is in a hurry to investigate the cause, and as soon as the details become clear, it will report including specific countermeasures. The time required for the survey is expected to be about one month, and shipment of this product will be suspended for the time being.

  • @Vitaliy_Kiselev Concerning. I've been interested in this lens. What's the source? Thanks.

  • You may have noticed a recent press release regarding the identification of a potential issue on an early production batch of the new SIGMA 28-70 F2.8 DG DN | C. It referenced a phenomenon where the lens’s ghost reduction coating deteriorated over time, potentially leading to increased ghosting in some shooting environments.

    We would like to inform you that these early lenses are in the process of being recalled from the small number of constomers affected and replaced with new ones. It only affects lenses with serial numbers prior to 55488834, regardless of mount. On all subsequent lenses the issue has been fully rectified.

    Please rest assured that in the UK fewer than five customers have been affected by this very isolated issue, and the customers have, or are in the process of, being contacted to arrange a replacement lens.

    We would like to thank you for your patience while we resolve the issue and if you have any further questions please do not hesitate to get in contact with the SIGMA UK team.
