Sigma 28-105mm F2.8 DG DN I Art (Sony E Mount)

Our thoughts

'We are thrilled to introduce this new breed of zoom lens. For a long time, the flexible range of a 24-105mm standard zoom lens has limited you to an F4 aperture (at best). But not anymore! At 158mm in length and less than a kilo in weight, this F2.8 lens is scarcely larger than a 24-70mm GM, but offers a zoom advantage that would previously have necessitated a second lens in your camera bag. All whilst maintaining an F2.8 aperture and the high quality that Sigma’s prestigious ART range has come to earn.'  

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-framemirrorless 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 hugerange of subjects and situations, from expansive low-light landscapesto portraits with big, beautiful bokeh, and thanks to SIGMA’s latest optical technology and the use oflarge diameter elements including FLD, SLD and five aspherical elements, it is able to do so with superbclarity and sharpness. This allows the lens to deliver exceptional versatility without compromising onoptical 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 andlightweight body weighing less than 1kg, making it an exceptional all-round choice for both stills and video.

Constant F2.8 aperture across aversatile 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 thoroughsuppression of optical aberrations within each lens group. And with its outstanding close-focusing capability when zoomed in, macro-style results are also possible.

A versatile F2.8 aperture perfect for portraits and low light

With its fast aperture across the whole focal range, the SIGMA 28-105mm F2.8 DG DN | Art isa true workhorse lens that can be used foralmost 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 F2.8maximum 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 SIGMA28-105mm 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 of1:3.1 for powerful macro-style results.

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.

Minimal focus breathing

Vital 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 pullswhen recording video, and easier image alignment when focus stacking
