SIGMA Sets New Standard for Large Aperture Zooms for Mirrorless Systems
The SIGMA 28-70 mm F2.8 DG DN | Contemporary redefines the standard zoom dedicated to mirrorless cameras by combining exceptional optical performance, a constant F2.8 aperture and a lightweight, compact construction. It is the smallest and lightest lens in its class *. True to the essence of the Contemporary line concept of maintaining an optimal balance between performance and lens size, this new optic delivers professional-quality results in a build small enough for everyday outings.

Designed based on SIGMA's Art series with the same optimum level of optical performance
The optical design of the SIGMA 28-70mm F2.8 DG DN | Contemporary is based on that of 24-70 mm F2.8 DG DN | Art, renowned for its exceptional optical performance over its entire focal range. True to the basic concept of the Contemporary series, the 28-70mm F2.8 DG DN | Contemporary was developed to offer the right balance between performance and portability. This large-aperture standard zoom offers exceptional image quality that rivals that of the Art Series lenses, in a construction light enough for everyday use. Thanks to state-of-the-art technology, the 28-70 mm F2.8 DG DN | Contemporary features an advanced optical design that includes three aspherical elements and two FLD and SLD glass elements. Despite the use of less elements than in the 24-70 mm F2.8 DG DN | Art, Its design allows for in-depth correction of longitudinal chromatic aberrations and sagittal coma, which cannot be corrected by the camera itself, allowing users to create uniformly sharp images from the center to the edges of the frame. In addition to removing ghosting, the use of the super multilayer coating in combination with the nanoporous coating provides good light control for high contrast results in backlit conditions. It also features a water and oil repellent coating on the front surface of the lens. allowing users to create uniformly sharp images from the center to the edges of the frame.

Lightweight and compact construction ideal for everyday use
By slightly decreasing the wide-angle of 28-70 mm F2.8 DG DN | Contemporary compared to 24-70 mm F2.8 DG DN | Art, the lens size could be reduced significantly. In order to accommodate the Contemporary Series concept, which balances performance and portability, this new lens features a simpler structure that is dust and splash proof, as well as smaller control knobs. That's what makes it the smallest and lightest lens in its class *. This new lens has only one very light focusing element, allowing for a reduced size AF unit. Along with this aspect, a quiet and fast stepping motor ensures responsive and near-silent autofocus performance. The 28-70 mm F2. 8 DG DN | Contemporary weighs 470g and when mounted on the SIGMA fp its total weight is 890g. Weighing less than 1 kg, its extreme portability gives photographers great latitude when it comes to choosing the equipment that will complement this light and easy to handle system that can easily be combined with a stabilizer or other accessories.

Very high build quality coupled with remarkable attention to detail that ensures an exceptional user experience
As optimum portability was a priority in the design, construction of the SIGMA 28-70mm F2.8 DG DN | Contemporary is mainly made up of light pieces. Although it is generally more difficult to ensure accuracy with plastic parts than with metal parts, no compromise has been made to the build quality of the 28-70mm F2.8 DG DN | Contemporary. This is explained by the type of polycarbonate used, TSC (Thermally Stable Composite), which has a level of thermal shrinkage comparable to that of aluminum. The differences between the thermal shrinkage of metal parts are thus reduced, ensuring stable performance levels even in an environment where temperature changes are extreme. The SIGMA 28-70 mm F2. 8 DG DN | Contemporary offers a new and improved photographic experience for users of mirrorless systems who desire a standard, fast aperture zoom. Thanks to its intuitive and premium design, it is as enjoyable to use this lens as it is to admire the stunning resulting images, inspiring you to realize your full creative potential.
