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. \u003c\/p\u003e\n\u003cp\u003eThe 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 1kg, making it an exceptional all-round choice for both stills and video. \u003c\/p\u003e\n\u003ch4\u003eConstant F2.8 aperture across a versatile 28-105mm zoom\u003c\/h4\u003e\n\u003cp\u003eMany 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 28-105mm 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA versatile F2.8 aperture perfect for portraits and low light\u003c\/strong\u003e\u003cbr\u003eWith its fast aperture across the whole focal range, the SIGMA 28-105mm 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFill the frame with superb close-up performance\u003c\/strong\u003e\u003cbr\u003eAchieving a minimum focus distance of just 40cm across its entire zoom range, the SIGMA 28-105mm 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. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuperior optical performance across the full zoom and focus range\u003c\/strong\u003e\u003cbr\u003eThe SIGMA 28-105mm 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 φ66.4mm 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesigned to minimize flare and ghosting\u003c\/strong\u003e\u003cbr\u003eUsing 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMinimal focus breathing\u003c\/strong\u003e\u003cbr\u003eVital for film-makers who demand consistent framing, the lens has been designed to keep focus breathing to a minimum. This ensures that any changes to the angle-of-view due to focus shift are minimized across the entire zoom range, ensuring natural-looking focus pulls when recording video, and easier image alignment when focus stacking.\u003c\/p\u003e\n\u003ch4\u003eSuperb portability thanks to a weight of less than 1kg\u003c\/h4\u003e\n\u003cp\u003eStandard zooms should be small and light enough for all-day hand-held shooting, so the SIGMA 28-105mm F2.8 DG DN | Art has been designed with portability in mind. It combines five aspherical elements effectively in place to shorten the overall length, and a magnesium-alloy construction around the mount, keeping the weight of the lens to less than 1kg. This ensures the lens has superb portability similar to shorter standard zoom lenses, while providing a wider zoom range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExcellent optical performance in a streamlined body\u003c\/strong\u003e\u003cbr\u003eBy using five aspherical elements in its optical construction, SIGMA has succeeded in significantly shortening the lens’s total length without any compromise to sharpness and image quality. This advanced configuration was only made possible by continuous technological innovation and cutting-edge manufacturing processes at SIGMA’s sole production base in Aizu, Japan.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSmarter design means lower weight\u003c\/strong\u003e\u003cbr\u003eConstant F2.8 zoom lenses can be heavy, but by optimizing the design and materials of each part of the SIGMA 28-105mm F2.8 DG DN | Art, SIGMA has achieved a remarkably light weight of less than 1kg. The use of magnesium-alloy rather than aluminum for the lens barrel around the mount has reduced the weight of these parts alone by two-thirds, while ensuring rigidity.\u003c\/p\u003e\n\u003ch4\u003eProfessional features, fast AF and excellent build quality\u003c\/h4\u003e\n\u003cdiv\u003eIn addition to high-speed AF delivered by its linear motor HLA (High-response Linear Actuator), the SIGMA 28-105mm F2.8 DG DN | Art packs in a range of features that help deliver the best possible results in every shooting situation. These include a dust- and splash-resistant structure and water- and oil-repellent coating, as well as a zoom lock switch, a de-clickable aperture ring, AFL buttons and the focus ring for easier handling including shooting with MF.\u003c\/div\u003e\n\u003cdiv\u003eA linear motor HLA for rapid and accurate AF\u003c\/div\u003e\n\u003cdiv\u003eThe lens incorporates a linear motor HLA (High-response Linear Actuator) that delivers a maximum drive speed, ensuring responsive, precise and smooth AF.
