Sigma 16-28mm f/2.8 DG DN Contemporary Lens

Sigma 16-28mm f/2.8 DG DN Contemporary Lens

The Sigma 16-28mm f/2.8 DG DN Contemporary Lens for L-Mount combines exceptional optical quality, a bright F2.8 constant aperture and a robust and lightweight body, opening up new possibilities shooters who need professional results in a compact package.

A fast f/2.8 constant aperture allows for the use of faster shutter speeds in low light scenarios as well as being especially useful for closeup shots thanks to its shallow depth of field.

With its excellent field curvature correction, the 16-28mm F2.8 DG DN | Contemporary is able to achieve exceptional edge-to-edge sharpness, which is essential for most wide-angle applications. It boasts five FLD elements and four aspherical lens elements to effectively suppress chromatic aberrations for improved image clarity and colour accuracy. Super Multi-Layer and Nano Porous Coatings have also been applied to improve contrast and colour rendering by reducing lens flare and ghosting when working in strong lighting conditions.

The lens has an inner zoom & focus mechanism that keeps the dimensions of the lens constant throughout the zoom range and at all focus distances. This design feature allows for almost no balance point shift and a fixed front element, making it an ideal instrument for videography, travel, and landscape photography.

Lightweight, versatile and with an exceptionally compact form-factor, weighing in at just 450g and measuring just 100.6mm in length, this lens makes for a highly practical optic that is portable enough for everyday shooting. It’s especially appealing for landscape, wedding and travel photographers who need to carry their kit for long periods.

Uncompromising optical performance

The 16-28mm F2.8 DG DN | Contemporary lens has been optimized with the latest optical design technology to deliver exceptional image quality despite its compact size. The two large-diameter aspherical lens elements and five ideally arranged FLD glass elements 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 achieve its impressive image quality.

An F2.8 constant aperture gives a shallow depth-of-field for blurry out-of-focus areas, and produces bokeh that is smooth and circular thanks to the nine rounded diaphragm blades.

SIGMA has also taken extensive measures to counter ghosting and lens flare, which are caused by reflections inside the lens barrel. Their 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.

Convenient form-factor

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.

A front filter thread has been built in, allowing the use of neutral density and polarizing filters - especially useful for landscape photographers and filmmakers looking for a versatile wide-angle lens.

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’ favourable 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.

Exceptional build quality

The lens is constructed using specially selected lightweight materials including Thermally Stable Composite (TSC), a polycarbonate with a thermal contraction rate similar to that of aluminium. This enables the lens to function at peak performance even in environments with harsh temperature differences, as the metal and plastic parts contract and expand at similar rates.
