The Sigma 28-70mm f/2.8 DG DN Contemporary redefines the standard zoom lens for mirrorless cameras, combining outstanding optical performance and a continuous f/2.8 aperture with a lightweight and compact body. Design-wise, the 28-70mm F2.8 DG DN Contemporary is based on the 24-70mm F2.8 DG DN Art, but with a focal length range starting at 28mm. This makes the lens body significantly smaller and lighter, with the same outstanding optical performance. Due to the slightly smaller wide-angle range of the 28-70mm F2.8 DG DN Contemporary compared to the 24-70mm F2.8 DG DN Art, the size of the 28-70mm body has been significantly reduced. The concept of the Contemporary product line balances performance and handiness. The lens features a single, lightweight focusing element, so the AF unit can also be kept small. Together with a quiet and fast stepping motor, this ensures responsive and virtually silent autofocus performance. The 28-70mm F2.8 DG DN Contemporary weighs 470g on its own and just 890g when combined with the Sigma fp, for example. At less than 1kg, such an outstandingly light camera system gives photographers an enormous amount of freedom and flexibility to realize their creative visions. It's also a perfect choice for filmmakers looking for a powerful, lightweight and easy-to-use camera system that works well with a gimbal and other accessories.
