A new high-performance, constant-aperture zoom is today added to the Sigma Art line. The Sigma 28-105mm F2.8 DG DN | Art is said to combine outstanding optical performance, impressive build quality and a range of pro-grade features. It aims to become one of the most versatile optics on the market for mirrorless systems. It is launched in L-Mount and Sony E-Mount.
Sigma 28-105: Latest optical technology
Clarity and sharpness is achieved by employing the latest optical technology, with large-diameter elements including FLD, SLD and five aspherical surfaces. The construction allows the lens to deliver “exceptional versatility without compromising on optical quality”. The Sigma 28-105mm F2.8 DG DN |Art includes high-speed autofocus with HLA technology, a rugged dust- and splash-resistant structure, and various functions such as an aperture ring, all included in a compact and lightweight body weighing less than 1 kg.
According to Sigma, the new lens is built to tackle a wide range of subjects and situations, from “expansive low-light landscapes to portraits with big, beautiful bokeh”.
Key Features
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 1 kg
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 1 kg. 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.

Disappointing that there is no image stabilisation.
I use the stabilised Panny 24-105 on my CL, SL, Fp, and the unstabilised 24-70 Leica on my SL2-S.
As I get older the more I appreciate how unsteady I’ve become!
At least the new 70-200 is stabilised, I might get that.
This will be an amazing lens for professionals! I suspect that Leica will bring out a Leica packaged version for those that appreciate the Leica name on their Sigma glass-so get yourself on the waitlist of your favourite local dealer.
