Covering an ultra-wide angle of 16mm and providing F2.8 aperture brightness, the lens configuration has been optimized using the latest optical design technology, achieving high optical performance and boldly reducing the size and weight of the lens body. Taking into account the scenes in which ultra-wide-angle lenses are used, the lens is designed to focus on correcting field curvature and deliver high performance with sharpness all the way to the periphery. In addition, a front filter can be attached for shooting scenes such as landscapes. By adopting an inner zoom that does not change the overall length when zooming, it maintains outstanding portability and stable operability. It's perfect for mountain photography that requires serious weight reduction, and for traveling where footwork is important. It condenses all of the high-definition depiction expected from a large-diameter zoom lens, pocketable size, and usability. To help you enjoy large-diameter, ultra-wide-angle zoom lenses more freely and easily. This is a new proposal from SIGMA. Uncompromising optical performance housed in a compact body The 16-28mm F2.8 DG DN | Contemporary was developed as a "high-performance compact zoom" that condenses uncompromising optical performance into a lightweight and compact lens body. The lens configuration has been optimized using the latest optical design that takes into account short flange back and optical correction functions on the camera side, achieving both high optical performance and compact size. In particular, the two large-diameter aspherical lenses on the front contribute to making the entire lens more compact and achieving high optical performance. Five pieces of FLD glass, which have the same characteristics as fluorite, are used and optimally arranged to effectively suppress lateral chromatic aberration and axial chromatic aberration, which are particularly problematic in ultra-wide-angle lenses. When shooting landscapes and architecture, where an ultra-wide-angle lens is useful, you can enjoy uniformly sharp depictions and beautiful bokeh from the center of the screen to the periphery. In addition, when taking close-up shots, it is possible to create images with a three-dimensional effect by taking advantage of the background blur that is unique to F2.8. With ultra-wide-angle zoom, it's easy for the sun to enter the screen, causing ghosting and flare, so we take precautions from the design stage. Adopts a super multi-layer coating to achieve excellent backlight performance.
