Sigma 28-105mm f/2.8 DG DN Art Lens for Sony E, Bundle with 82mm CPL Filter, 82mm UV Filter, Pen Lens Cleaner and Software Kit

Compact, full-frame artistic lens
The SIGMA 28-105mm F2.8 DG DN | Art lens is a compact, full-frame, wide-angle to telephoto zoom lens. It has a versatile zoom range including the popular 85mm focal length, preferred in portrait photography.

Art Line
Designed with a focus on sophisticated optical performance and tremendous expressive power, our Art line delivers high-level artistic quality.

Dust and splash-resistant structure
A highly-effective dust and splash resistant structure is built into the lens barrel, with special sealing at the mount connection, focus and zoom rings, and other lens controls.

HLA (High-response Linear Actuator)
HLA is SIGMA's proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.

TSC (Thermally Stable Composite)
TSC is a type of polycarbonate with a thermal expansion rate similar to that of aluminum. By using a combination of TSC and aluminum parts, lenses can be considerably more lightweight without sacrificing durability and operability.

High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Versatile F2.8 maximum aperture
The maximum aperture of F2.8 provides outstanding versatility in a zoom lens, offering excellent low-light performance, and the ability to create beautiful bokeh and subject separation.

Manual Aperture Ring
A manual control ring allows the user to change aperture via the lens for a more direct, tactile approach.

Click / De-Click switch
A click / de-click switch allows the user to select their preference for aperture control, with either smooth transitions or marked click stops.

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.

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 true workhorse lens that can be 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, 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 F2.8 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 very useful maximum magnification ratio of 1:3.1 for powerful macro-style results.

Superior optical performance across the full zoom and focus range
The Sigma 28-105mm F2.8 DG DN | Art operates without compromise, suppressing aberrations very effectively within each lens group, and throughout the entire zoom and focal range. This ensures the lens has a consistent performance 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 66.4mm element.

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 pulls when recording video, and easier image alignment when focus stacking.

Superb portability thanks to a weight of less than 1kg
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 1kg. This ensures the lens has superb portability similar to shorter standard zoom lenses, while providing a wider zoom range.

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 any compromise to sharpness and image quality.

Smarter design means lower weight
Constant F2.8 zoom lenses can be heavy, but by optimizing 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. The use of magnesium-alloy rather than aluminum for the lens barrel around the mount has reduced the weight of these parts alone by two-thirds, while ensuring rigidity.

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.

Two AFL buttons for added customization
Located on the side and on top of the barrel, two customizable AFL buttons can easily be reached in either horizontal or vertical shooting positions, ensuring more ergonomic handling.

Zoom lock switch to keep the zoom ring secure
The lens is equipped with a zoom lock switch that holds the zoom mechanism in place at its wide end, preventing it from extending unintentionally under its own weight when carried. The lock can be released by the switch, or by turning the zoom ring for a faster and more flexible workflow.

Petal-type hood
A dedicated petal-shaped hood is supplied. A locking mechanism is provided for secure attachment.

Inner focus system
To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

Compatible with Lens Aberration Correction
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

Super Multi-Layer Coating
Sigma's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma's Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.

Nano Porous Coating
NPC (Nano Porous Coating) incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.

Water and oil repellent coating
Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and grease from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.
