Sigma 28-70mm f/2.8 DG DN Contemporary Lens - Sony E-Mount

The technical details behind this lens

Sigma 28-70mm f/2.8 DG DN Contemporary Lens - Sony E-Mount offers reliable design and performance. This lens features just one lightweight focusing element, which keeps the AF unit small. Along with a quiet and fast stepping motor, makes for responsive and near-silent autofocus performance, a perfect combination for filmmakers looking for a high-performance, lightweight, and easy-to-handle camera system that works very well with a gimbal or other accessories. It is a versatile wide-angle to portrait-length zoom distinguished by its f/2.8 constant maximum aperture. The design suits working in available lighting conditions while affording increased control over the depth of field. More lightweight and compact than similar 24-70mm lenses, its optical design 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 colour accuracy. It features a rounded nine-blade diaphragm for a pleasing bokeh quality.
