Harness the power of this versatile and portable F2.8 optic with an extended 28-105mm focal range – a standard zoom that goes well beyond standard.

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.

Achieving 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.

Superior optical performance across the full zoom and focus range

The 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.

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.

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.

For quick changes to exposure, or a more traditional way of shooting, the lens is equipped with a dedicated aperture ring, allowing the user to change aperture via the lens if preferred. An aperture ring click switch is a useful tool for film-makers, and a lock switch helps ensure the aperture ring is not knocked out of its setting accidentally.

The lens has a dust- and splash-resistant structure* that keeps it free of contaminants in harsh outdoor environments. The front element also features a water- and oil-repellent coating that helps keep it clean in adverse shooting conditions.

* The structure is designed to be dust- and splash-resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.
