Sigma 28-70mm
Sigma 28-70mm f2.8 DG DN for Sony E – Mirrorless Lens. The 28-70mm f2.8 DG DN Contemporary Lens for Sony E-Mount from Sigma is a versatile wide-angle to portrait-length zoom characterized by its f2.8 constant maximum aperture. The design suits working in available lighting conditions while affording increased control over depth of field.
More lightweight and compact than similar 24-70mm lenses, it’s 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 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.
Each optical surface features Super Multi-Layer and Nano Porous coatings to improve contrast and colour rendering by suppressing lens flare and ghosting for optimal light transmission, and an added water- and oil-repellent coating on the front optic helps keep the lens free from smudges and droplets.
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.
