Sigma 16-28mm F/2.8 Dg Dn Contemporary Lens For Sony E Mount

The full-frame SIGMA 16-28mm F2.8 DG DN | Contemporary combines exceptional optical quality, a bright F2.8 constant aperture and a robust and lightweight body, opening up new possibilities for Sony E-mount mirrorless camera shooters who need professional results in a compact package.

Uncompromising optical performance within a compact bodyOptimized 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.Convenient form-factor allowing more freedom and usabilityThe 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.Exceptional build quality with intuitive ergonomicsThe 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 SIGMAs staff, the companys unparalleled manufacturing technology and the rigorous quality control at SIGMAs only production base in Aizu, Japan.Compact and lightweight, the 16-28mm F2.8 DG DN | Contemporary lens is a sophisticated but versatile photographic tool that offers photographers and filmmakers the perfect blend of portability and performance.Additional FeaturesLens construction: 16 elements in 11 groups, with 5 FLD and 4 aspherical lens elementsInner zoomInner focus systemCompatible with high-speed autofocusStepping MotorCompatible with front filter (72mm)Compatible with Lens Aberration Correction(available on supported cameras only)Super Multi-Layer CoatingFocus Mode switchSupport for DMF and AF+MFPetal-type lens hood(LH756-01)Mount with dust and splash-resistant structureDesigned to minimize flare and ghostingEvery single lens is evaluated with SIGMAs proprietary MTF measuring system9-blade rounded diaphragmHigh-precision, durable brass bayonet mount
