SIGMA 16-28mm F2.8 DG DN Lens (Sony E Mount)

Optimized with the latest optical design technology, the 16-28mm F2.8 DG DN | Contemporary is a high-performance optic that delivers exceptional image quality despite its compact size. The two large-diameter aspherical lens elements and five ideally arranged FLD glass elements (whose characteristics mirror that of fluorite) keep the lens light and compact while effectively suppressing the lateral and axial or longitudinal chromatic aberrations that often diminish the image quality of other ultra-wide lens designs. The lens also utilizes the advanced digital correction capabilities of modern cameras to enable it to achieve such impressive image quality from such a small body.

An F2.8 constant aperture gives a shallow depth-of-field for blurry out-of-focus areas, which is especially useful when shooting close-ups. The bokeh is smooth and circular thanks to the nine rounded diaphragm blades, which means the background never distracts from the in-focus subject.

SIGMA has also taken extensive measures to counter ghosting and lens flare, which are caused by reflections inside the lens barrel. The Super Multi-Layer Coating ensures that the 16-28mm F2.8 DG DN | Contemporary delivers punchy, high contrast results even in the most difficult of backlit conditions.

The new 16-28mm has a front filter thread built in, which allows neutral density and polarizing filters to be attached more easily. This is especially useful for landscape photographers and filmmakers.

By using a stepping motor to control the AF actuator, the autofocus of the 16-28mm F2.8 DG DN | Contemporary is both fast and silent, making it ideal for shooting photography and video in quiet environments.

The inner zoom mechanism allows the lens to maintain the same length throughout the entire zoom range and with almost no shift to its balance point. The resulting stability will be appreciated by anyone looking to use the lens with a gimbal, or for hand-held or vlog-style video shoots. The inner zoom mechanism also greatly contributes to the lens’ favorable physical dimensions: at a length of 100.6mm, a diameter of 77.2mm and a weight of only 450g*, its compactness rivals wide-angle zooms with slower maximum F4 apertures.
