Released in June 2022 *Image is for illustrative purposes only. Camera not included. A large-aperture ultra-wide-angle zoom lens developed with the concept of high-performance compact zoom. Mount: Leica Camera L-Mount standard compliant. Focal length: 16-28mm. Maximum aperture: F2.8. Filter diameter: 72mm. Contemporary line / [1628MMF28DGDNCL] 1628MMF28DGDNCL Released in June 2022 A new form of ultra-wide-angle zoom that gives you more freedom and ease. A large aperture of F2.8, an ultra-wide-angle 16mm. A new option for high-performance compact zoom. Uncompromising optical performance in a compact body. The 16-28mm F2.8 DG DN | Contemporary was developed as a high-performance compact zoom that packs uncompromising optical performance into a lightweight, compact lens body. The latest optical design, taking into account the camera's optical correction function and a short flange focal distance, optimizes the lens construction, achieving both high optical performance and a compact design. The two large-diameter aspherical lenses at the front contribute to the overall compactness of the lens and its high optical performance. The optimal placement of five FLD glass elements, which have the same properties as fluorite, effectively suppresses lateral chromatic aberration and axial chromatic aberration, which are particularly problematic in ultra-wide-angle lenses. When photographing landscapes and architecture, which are often favored by ultra-wide-angle lenses, you can enjoy consistently sharp images from the center to the edges and beautiful bokeh. Furthermore, close-up shots take advantage of the background bokeh unique to the F2.8 aperture, creating a three-dimensional image. Ultra-wide-angle zooms are prone to sunlight entering the frame, which can cause ghosting and flare, and this was thoroughly addressed from the design stage. The Super Multi-Layer Coating ensures excellent backlight performance. Expanding photographic freedom and expressive possibilities: The 16-28mm F2.8 DG DN | Contemporary lens is compatible with a 72mm front filter. This lens makes it easier to use PL and ND filters, which are often used in ultra-wide-angle photography. The AF actuator uses a stepping motor. The agile and quiet AF is ideal for both still and video shooting. The inner zoom maintains its compact size, maintaining its overall length even when changing focal lengths, resulting in virtually no shift in the center of gravity. This makes it ideal for handheld shooting, gimbal shooting, and vlogging, where stability and mobility are required. The inner zoom also contributes to its compact size, with a total length of 100.6mm, maximum diameter of 77.2mm, and weight of just 450g, almost on par with an F4 lens. When combined with the 28-70mm F2.8 DG DN | Contemporary lens from the same F2.8 Zoom Series, you can create an extremely compact system that covers ultra-wide-angle to medium telephoto focal lengths, weighing just 920g.
Experience intuitive operation and high precision with this build quality. The lens body, designed for portability, is constructed primarily from lightweight plastic parts. While plastic parts are generally considered more difficult to machine with precision than metal parts, the 16-28mm F2.8 DG DN | Contemporary makes no compromises when it comes to build quality. It uses TSC (Thermally Stable Composite) polycarbonate in strategic locations, which has a thermal contraction rate similar to that of aluminum. This minimizes errors caused by thermal contraction with metal parts and ensures stable performance even in environments with large temperature fluctuations. Furthermore, the pursuit of component precision and aesthetic beauty is made possible thanks to the advanced manufacturing technology and strict quality control of SIGMA's Aizu factory. More than just a convenient and compact zoom lens, this lens also delivers exceptional operability and elegance as a photographic tool.
