Sigma 28-105mm f2.8 DG DN Art Lens - Sony E Mount
Constant F2.8 aperture across a versatile 28-105mm zoom
The SIGMA 28-105mm F2.8 DG DN | Art is a zoom lens that maintains a constant F2.8 aperture throughout its focal range, providing consistent light-gathering and depth-of-field benefits. This lens is designed to minimize optical aberrations within each lens group, resulting in high optical performance. Additionally, it has impressive close-focusing capability when zoomed in, allowing for macro-style photography.
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 is a workhorse lens used for almost any type of photography. Scenic photographers can shoot wide-angle landscapes, using the F2.8 aperture for low-light scenes and twilight urban views. At the same time, the middle focal lengths tackle dimly lit documentary and street subjects, allowing shutter speeds one stop faster than comparable lenses. At the long end, famous portrait focal lengths from 85mm and 105mm, combined with the F2.8 maximum 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 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 beneficial maximum magnification ratio of 1:3.1 for powerful macro-style results.
Superior optical performance across the entire zoom and focus range
The SIGMA 28-105mm F2.8 DG DN | Art operates without compromise, suppressing aberrations within each lens group and throughout the entire zoom and focal range. This ensures the lens consistently performs 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.
Designed to minimize flare and ghosting
Flare and ghosting have been primarily eliminated using advanced simulation technology, ensuring 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 suppress flare and ghosting further.
Minimal focus breathing
Vital for film-makers who demand consistent framing, the lens has been designed to minimize focus breathing. 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 pulls when recording video and easier image alignment when focus stacking.
Excellent optical performance in a streamlined body
By using five aspherical elements in its optical construction, SIGMA has succeeded in significantly shortening the lens’s total length without compromising sharpness and image quality. This advanced configuration was only made possible by continuous technological innovation and cutting-edge manufacturing processes at SIGMA’s sole production base in Aizu, Japan.
A smarter design means lower-weight
Constant F2.8 zoom lenses can be heavy, but by optimising the design and materials of each part of the SIGMA 28-105mm F2.8 DG DN | Art, SIGMA has achieved a remarkably light weight of less than 1kg. Using magnesium alloy rather than aluminium for the lens barrel around the mount has reduced the weight of these parts alone by two-thirds while ensuring rigidity.
