The Sigma 20mm F2 DG DN Contemporary is an ultra-compact and lightweight, wide-aperture, full frame prime lens for Sony E-mount mirrorless cameras. Weighing in at only 370g and measuring just 72.4mm in length, this lens is portable enough for everyday shooting. It’s ideal for landscapes, wide-angle portraits, weddings and interiors, and is particularly well-suited to astrophotography owing to its well controlled saggital coma flare. Optical performance The 20mm F2 DG DN Contemporary achieves the highest level of optical performance even wide open, from the centre of the image to the periphery. Based on the latest optical design technology, the lens construction includes three high-precision glass-molded aspherical lens elements, one SLD element, and one FLD element to suppress a range of optical aberrations. The result is clear and sharp images even in the extreme corners of the frame. By focusing on the suppression of sagittal coma flare, accurate production of very bright points of lights has been achieved. . This provides extremely detailed results across the entire image, which is especially important for night sky photography. The lens’ advanced optical design, as well as its Super Multi-Layer Coating and Nano Porous Coating (NPC), ensures minimal flare and ghosting. This makes it easier tp photograph backlit subjects and still achieve high contrast results. Exceptional build quality All I series lenses have an all-metal construction. The precision cut aluminium parts not only give the barrel a sleek, stylish finish, but provides superb durability that improves the quality of the entire product. Metal materials are also used in internal structures that slide with the operation ring for added robustness.
