The SIGMA 28-105mm F2.8 DG DN | Art 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 1kg, making it an exceptional all-round choice for both stills and video.

Constant F2.8 aperture across a versatile 28-105mm 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 28-105mm 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.

Superb portability thanks to a weight of less than 1kg

Standard 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. Excellent optical performance in a streamlined body

Professional features, fast AF and excellent build quality

In 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.
