Sigma 28-70mm F2.8 DG DN Contemporary Lens (Sony E)

The 28-70mm f/2.8 DG DN Contemporary Lens for Sony E-Mount from Sigma is a versatile wide-angle to portrait-length zoom characterized 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 color accuracy. 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. The weather-sealed design benefits working in trying environmental conditions, and a nine-blade rounded diaphragm contributes a pleasing bokeh quality when using wider apertures. Standard zoom for full-frame E-mount mirrorless cameras. Two F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements reduce chromatic aberrations and color fringing. Both Super Multi-Layer and NanoPorous coatings minimize lens flare and ghosting and produce contrast-rich and color-neutral imagery.
