The Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E-Mount is a versatile wide-angle to portrait-length zoom characterized by its f/2.8 constant maximum aperture. 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.
More lightweight and compact than similar 24-70mm lenses, its optical design is based on the 24-70mm F2.8 DG DN | Art and incorporates two FLD and two SLD low-dispersion elements plus three aspherical elements that reduce a variety of aberrations to achieve high sharpness, enhanced clarity, and improved color accuracy.
The Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E-Mount 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, an ideal combination for filmmakers looking for a high-performance, lightweight, and easy-to-handle camera system that works well with a gimbal or other accessories.
