Sigma 28-105mm f2.8 DG DN (A) L-Mount

Sigma 28-105mm f2.8 DG DN (A) L-Mount

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 speed of F2.8, it combines outstanding optical performance with excellent build quality. It also offers a range of professional features that make it one of the most versatile lenses on the market for mirrorless system cameras with a full-frame sensor.

Thanks to SIGMA's latest optical technology and the use of large-diameter lenses, including FLD, SLD and five aspherical elements, it is capable of mastering a wide range of photographic situations - from detailed landscape shots to portraits with harmonious bokeh.

The lens offers exceptional versatility without compromising on optical quality. A high-speed autofocus with HLA technology, the robust, dust and splash-proof construction and various features, such as the de-clickable aperture ring, are among the high-quality features. With a compact and lightweight body and a weight of less than 1 kg, the SIGMA 28-105mm is an exceptional all-round lens - both for photos and videos.

Versatile 28-105mm Zoom with constant F2.8 aperture

Many conventional Zoom lenses with a focal length of up to 105mm do not offer a constant aperture of F2.8 and usually stop down to F4 at the telephoto end. The SIGMA 28-105mm F2.8 DG DN Art offers the advantages of a continuous F2.8 aperture, such as light intensity and variability of depth of field over the entire focal length range. Its optical performance is also extremely high over the entire Zoom range. The consistently thorough reduction of optical aberrations within each lens group ensures outstanding results. Its outstanding close focusing distance also enables close-ups with a reproduction scale of approx. 1:3 in the telephoto range.

F2.8 - perfect for portraits and in low light conditions

With its high speed over the entire focal length range, the SIGMA 28-105mm F2.8 DG DN Art is a real working lens that can be used for almost any type of photography. Landscape photographers benefit from wide-angle shots with enormous three-dimensionality, while the large Zoom range offers great flexibility in reportage photography. At the same time, the continuous F2.8 aperture ensures faster shutter speeds than an F4 with comparable lenses and therefore provides sufficient scope for working in poor lighting conditions or at dusk. The Zoom range from 85mm to 105mm benefits portrait photographers. In combination with the large aperture of F2.8, a shallow depth of field is achieved, which impressively isolates the main subject against a background with large and soft bokeh.

Outstanding close-ups

With a focusing distance of just 40 cm over the entire focal length range, the SIGMA 28-105mm F2.8 DG DN Art brings you close to the subject for images with a wealth of detail. The magnification of 1:3.1 at 105mm focal length ensures impressive results for close-ups.

Superior optical performance over the entire focal length and focus range

The SIGMA 28-105mm F2.8 DG DN Art works uncompromisingly and suppresses aberrations very effectively within each individual lens group over the entire focal length and focus range. This ensures that the lens delivers consistently high performance despite its large Zoom range. This is thanks to the modern, high-quality optical design of the lens. This includes two FLD, one SLD and five aspherical elements, including an element with a diameter of 66.4mm in the first group. Such large elements are very difficult to manufacture. SIGMA's decades of experience in the field of optical design and the advanced manufacturing technology of the SIGMA factory in Aizu, Japan, make this possible.

Low susceptibility to flares and ghosting

Flares and ghosting, which affect image quality, have been optimized for all lighting conditions using state-of-the-art simulation technology. In addition, SIGMA uses Nano Porous and Super Multi-Layer lens coatings on this lens to prevent flares and ghosting as far as possible. This means that brilliant, high-contrast images are possible even in unfavourable lighting conditions.

Minimized focus breathing

For filmmakers, a constant image section is of crucial importance. For this reason, great importance was attached to reducing focus breathing to a minimum during the development of the lens. This ensures that changes in the image angle due to focus shifts are minimized over the entire Zoom range. This ensures natural-looking focus shifts when shooting video and easier image alignment when focus stacking.

Outstanding handiness thanks to a weight of less than 1 kg

Standard Zooms should be small and light enough to shoot handheld for long periods of time. That's why the SIGMA 28-105mm F2.8 DG DN Art was developed with mobility in mind. It combines five aspherical elements, which shorten the overall length of the lens, with a magnesium alloy construction that limits the weight of the lens to less than 1 kg. This makes the lens similarly manageable to shorter standard Zoom lenses, while offering a wider Zoom range.

Outstanding optical performance in a slim body

By using five aspherical elements in the optical design, SIGMA has succeeded in significantly shortening the overall length of the lens without compromising on sharpness and image quality. This advanced design was only possible through continuous technological innovation and state-of-the-art manufacturing processes at SIGMA's sole production facility in Aizu, Japan.

Smarter design means lighter weight

Zoom Lenses with a constant F2.8 aperture can be heavy. By optimizing the design and materials of the SIGMA 28-105mm F2.8 DG DN Art, SIGMA has achieved a remarkably low weight of less than 1 kg. By using a magnesium alloy instead of aluminum for the lens barrel around the lens mount, the weight of these parts alone has been reduced by two-thirds while maintaining rigidity.

Professional features, fast autofocus and excellent workmanship

In addition to the fast autofocus provided by the HLA (High-Response Linear Actuator) linear motor, the SIGMA 28-105mm F2.8 DG DN Art has a range of features that help to achieve the best possible results in any shooting situation. These include a dust and splash-proof construction and the water and oil-repellent coating on the front lens. A Zoom lock switch, the de-clickable aperture ring, two AFL buttons and the focus ring, which can be operated precisely for MF shots, are further professional features.

An HLA linear motor for fast and precise AF

The lens is equipped with an HLA (High-response Linear Actuator) linear motor, which offers a high drive speed as well as responsive, precise and smooth AF. Thanks to its virtually silent operation, it is also suitable for video recordings.

Aperture ring with "de-click function"

Many demanding users appreciate the ability to set the aperture directly on the aperture ring of the lens. The SIGMA 28-105mm F2.8 DG DN Art therefore offers an aperture ring. Thanks to its "de-click function", this feature is also interesting for filmmakers, as the aperture can be adjusted smoothly and silently in this position. Those who prefer to set the aperture on the camera body can use the aperture ring's lock function and are protected against accidental adjustment.

Equipped with two AFL buttons

The lens has two AFL buttons, which have been positioned for optimum accessibility when shooting in portrait and landscape format. These buttons can be assigned individual functions with compatible cameras*

*Only in combination with compatible cameras. The available functions may vary depending on the camera used.

Zoom lock switch

The lens is equipped with a Zoom lock switch, which locks the Zoom mechanism in the wide-angle range and prevents the tube from extending unintentionally due to its own weight. The lock can be released not only via the switch, but also by turning the Zoomring, which enables quick and flexible handling for spontaneous shots.

Protected from external influences

In addition to the dust- and splash-proof housing*, the front lens of the lens has a water- and oil-repellent coating.

The lens is protected against dust and splash water, but is not waterproof.

Including lockable tulip-shaped lens hood

The specially adapted lens hood LH878-07 is included with the SIGMA 28-105mm F2.8 DG DN Art. This is securely locked in place with a quick twist and can be attached to the lens upside down for space-saving storage.
