20mm F2 DG DN Contemporary - Sony E

												

This ultra-compact, wide-aperture prime lens for E-mount and L-Mount systems is a game changer for mirrorless users needing a sharp, wide-angle optic that isn’t going to weight them down. This portable, full-frame premium compact prime for mirrorless cameras is the seventh lens in SIGMA’s fast-growing I series line-up, combining a bright maximum aperture of F2, an ultra-wide 20mm focal length and stunning optical performance. It’s also the widest lens in the range so far, opening up new photographic possibilities for I series users.

The lens boasts an exceptionally small form factor, weighing in at just 370g and measuring just 72.4cm in length*, which makes it a highly practical optic that 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 very well-controlled sagittal coma flare. It’s the fourth I series lens with an F2 aperture, joining a 24mm, 35mm and 65mm, which together make a well-matched lens set for photographers who need both performance and portability in their kitbag. Remarkably, the 20mm F2 DG DN | Contemporary is almost identical in size and weight to the SIGMA 24mm F2 I series. Its sleek, all metal design, with a signature I series magnetic lens cap, a manual aperture ring and exceptional build quality makes using this lens is a highly intuitive and satisfying experience.

New standards of optical performance for the contemporary line

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-moulded 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, which is difficult to correct in postprocessing, accurate reproduction of very bright points of light 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 very minimal flare and ghosting even when shooting into bright light sources. This makes it much easier to photograph backlit subjects and still achieve punchy, high contrast results.

Exceptional I series build quality with a compact form-factor

All I series lenses have an all-metal construction. The precision cut aluminium parts not only give the barrel a sleek, stylish finish, but provide 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. These high-precision components crafted with SIGMA’s cutting-edge metalworking technology are also used in SIGMA’s CINE LENS line-up for professional cinematographers and provide a tactile, ergonomic feel that make the lens a pleasure to use. The cover ring between the focus ring and the aperture ring has hairline processing that is also used for the rear cylinder of the Art line. This covering functions as a finger hold when attaching or detaching the lens.
