SIGMA 28-105mm F2.8 DG DN Art Lens with Durable Construction and High-Speed Autofocus (Sony E-Mount)

The SIGMA 28 to 105mm F2.8 DG DN Art Lens for Sony E-Mount is more than the conventional zoom lens. Thanks to the 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 slew of pro-grade features to make it one of the most versatile optics available for mirrorless cameras. The lens is designed to handle a wide range of subjects and situations, from broad low-light landscapes to portraits with large, beautiful bokeh, and it does so with exceptional clarity and sharpness thanks to SIGMA's cutting-edge optical technology and the use of large diameter elements such as FLD, SLD, and five aspherical elements. This allows the lens to offer extraordinary adaptability without sacrificing optical quality. The lens also features high-speed AF with HLA technology, a durable dust- and splash-resistant structure, and several features like as an aperture ring, all housed in a compact and lightweight body weighing less than 2.2 lbs, making it an excellent all-around pick for both images and videos.

Uninterrupted F2.8 Aperture

Most traditional zoom lenses with a reach of up to 105mm do not have a continuous F2.8 aperture and typically drop to F4 at the long end. However, the SIGMA 28 to 105mm F2.8 DG DN Art provides the same excellent light-gathering and depth-of-field benefits throughout the focal range. The lens provides all of this, as well as extraordinarily excellent optical performance, thanks to the complete suppression of optical aberrations within each lens group. When zoomed in, it also has excellent close-focusing capabilities, allowing for macro-style effects.

Versatile Aperture for Low-Light Images

Thanks to its fast aperture across the whole focal range, the SIGMA 28 to 105mm F2.8 DG DN Art is a genuine workhorse lens suitable for nearly any form of photography. Scenic photographers can capture wide-angle landscapes with the F2.8 aperture for low-light situations and twilight cityscape views, while the medium focal lengths are ideal for dimly lit documentary and street subjects, allowing shutter speeds one stop faster than similar lenses. Popular portrait focal lengths of 85mm and 105mm, combined with an F2.8 maximum aperture, give a shallow depth-of-field that effectively isolates a subject against a huge and lovely bokeh.

Excellent Close-Ups

The SIGMA 28 to 105mm F2.8 DG DN Art has a minimum focus distance of only 40cm over its entire zoom range, allowing you to get closer to your subject while filling the frame with detail and richness. At 105mm, this produces a very useful maximum magnification ratio of 1:3.1, ideal for powerful macro-style effects.

Excellent Optical Performance

The SIGMA 28 to 105mm F2.8 DG DN Art performs flawlessly, successfully suppressing aberrations within each lens group and over the whole zoom and focal range. This guarantees that the lens performs consistently even over a long zoom range. The lens's premium optical design includes two FLD, one SLD, and five aspherical elements. The first group uses a large-diameter phi 66.4mm element, which is extremely difficult to produce and only available thanks to SIGMA's advanced manufacturing technology at its sole production base in Aizu, Japan.

Minimal Flaring and Ghosting

Flare and ghosting have been largely removed by advanced simulation technology, ensuring that the lens produces rich, high-contrast images in any settings. Additionally, SIGMA's Nano Porous Coating and Super Multi-Layer Coating have been used to reduce flare and ghosting.

Reduced Focus Breathing

The lens has been engineered with minimal focus breathing, which is critical for filmmakers who require constant framing.
