Sigma 16-28mm F2.8 DG DN Lens for L Mount

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 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 (L-Mount Version), 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. 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 largediameter 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 vertical chromatic aberrations that often diminish the image quality of other ultra-wide lens designs. Capture moments in stunning detail!!!
