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

Effortless freedom

With its excellent field curvature correction, the Sigma 16-28mm f/2.8 DG DN Contemporary Lens 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 ensure optimal image quality with minimal aberrations. The lens has an inner zoom mechanism that keeps overall length consistent throughout the entire zoom range, helping it feel balanced in the hand. The inner zoom also means the lens’ center of gravity stays fairly constant, so it’s perfect for gimbal use. A front filter thread allows filters to be attached more easily. The lens boasts an exceptionally compact form factor, weighing in at just 450g and measuring just 100.6mm in length*, which makes it 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

Optimized with the latest optical design technology, the Sigma 16-28mm f/2.8 DG DN Contemporary Lens 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.

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 aluminum. 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. The precision of each individual component and the simple beauty of the finished product are made possible thanks to the craftsmanship and expertise of SIGMA’s staff, the company’s unparalleled manufacturing technology and the rigorous quality control at SIGMA’s only production base in Aizu, Japan.
