Description
The SIGMA 28 to 105mm F2.8 DG DN Art Lens for L-Mount is not just another standard zoom lens. With a powerful wide-angle to medium telephoto focal length and a bright F2.8 aperture throughout, this full-frame mirrorless zoom combines outstanding optical performance, superb build quality and a range of pro-grade features to make it one of the most versatile optics on the market for mirrorless systems. The lens is built to tackle a huge range of subjects and situations, from expansive low-light landscapes to portraits with big, beautiful bokeh, and thanks to SIGMA’s latest optical technology and the use of large diameter elements including FLD, SLD and five aspherical elements, it is able to do so with superb clarity and sharpness. This allows the lens to deliver exceptional versatility without compromising on optical quality. The lens also includes high-speed AF with HLA technology, a rugged dust- and splash-resistant structure, and various functions such as an aperture ring, all packed into a compact and lightweight body weighing less than 2.2 lbs, making it an exceptional all-round choice for both stills and video. Constant F2.8 Aperture across a Versatile 28 to 105mm Zoom Many conventional zoom lenses which have a reach up to 105mm do not offer a constant F2.8 aperture, usually dropping to F4 at the long end. But the SIGMA 28 to 105mm F2.8 DG DN Art delivers the same impressive light-gathering and depth-of-field benefits across the whole focal range. The lens offers all of this along with extremely high optical performance thanks to the thorough suppression of optical aberrations within each lens group. And with its outstanding close-focusing capability when zoomed in, macro-style results are also possible. Versatile F2.8 Aperture Perfect for Portraits and Low Light With its fast aperture across the whole focal range, the SIGMA 28 to 105mm F2.8 DG DN Art is a true workhorse lens that can be used for almost any type of photography. Scenic photographers can shoot wide-angle landscapes, using the F2.8 aperture for low-light scenes and twilight urban views, while the middle focal lengths tackle dimly lit documentary and street subjects, allowing shutter speeds one stop faster than comparable lenses. At the long end, popular portrait focal lengths from 85mm and 105mm, combined with the F2.8 maximum aperture, produce a shallow depth-of-field that will isolate a subject impressively against large and beautiful bokeh. Fill the Frame with Superb Close-Up Performance Achieving a minimum focus distance of just 40cm across its entire zoom range, the SIGMA 28 to 105mm F2.8 DG DN Art can get you closer to your subject, filling the frame with detail and texture. At its 105mm setting, this creates a very useful maximum magnification ratio of 1:3.1 for powerful macro-style results. Superior Optical Performance across the Full Zoom and Focus Range The SIGMA 28 to 105mm F2.8 DG DN Art operates without compromise, suppressing aberrations very effectively within each lens group, and throughout the entire zoom and focal range. This ensures the lens has a consistent performance even with such a long zoom range. This is thanks to the lens’s premium optical design, which includes two FLD, one SLD and five aspherical elements, the first grouping of which uses a large-diameter phi 66.4mm element that is extremely difficult to produce and only available thanks to SIGMA’s advanced manufacturing technology at its sole production base in Aizu, Japan. Designed to Minimize Flare and Ghosting Using advanced simulation technology, flare and ghosting have been largely eliminated, ensuring that the lens renders rich, high-contrast results in all conditions. In addition, SIGMA’s Nano Porous Coating and Super Multi-Layer Coating have been applied to further suppress flare and ghosting.
