Sigma 28-105mm F2.8 DG DN Art – L Mount

Description

Sigma 28-105mm F2.8 DG DN Art – L Mount (636969), is not another standard zoom lens, it is one of the most versatile optics in the market for mirrorless systems. With a 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 range of pro-grade features. A lens that is built to tackle a huge range of subjects and situations, from expansive low-light landscapes to portraits with big, beautiful bokeh, and thanks to SIGMAS latest optical technology and the use of large diameter elements including FLD, SLD and five aspherical elements, it is able so with superb clarity and sharpness. This allows the lens to deliver exceptional versatility without compromising on optical 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 and lightweight body weighing less than 1kg, making it an exceptional all-round choice for both stills and video.

Versatile F2.8 Aperture 

perfect for portraits and low Light photography, the SIGMA 28-105mm F2.8 DG DN | Art is a true workhorse lens that can be used for almost any type of photography, with its fast aperture across the whole focal range. 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.

Close-Up Performances

Fill the frame with amazing close-ups, the SIGMA28-105mm F2.8 DG DN | Art can get you closer to your subject achieving a minimum focus distance of just 40cm across its entire zoom range. At its 105mm setting, this creates a very useful maximum magnification ratio of1:3.1 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. 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

With 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.

Lightweight and portable

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. 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.

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.

A linear motor HLA for rapid and accurate AF

The lens incorporates a linear motor HLA (High-response Linear Actuator) that delivers a maximum drive speed, ensuring responsive, precise and smooth AF. With its high level of quietness, the motor also provides noise-free video capability.

An aperture ring for improved ergonomics

For quick changes to exposure, or a more traditional way of shooting, the lens is equipped with a dedicated aperture ring, allowing the user to change aperture via the lens if preferred. An aperture ring click switch is a useful tool for film-makers, and a lock switch helps ensure the aperture ring is not knocked out of its setting accidentally.

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.

^{* Assignment of functions is limited to supported cameras and assignable functions vary depending on the camera.}

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.

Weather-resistant structure for challenging conditions

The lens has a dust- and splash-resistant structure* that keeps it free of contaminants in harsh outdoor environments. The front element also features a water- and oil-repellent coating that helps keep it clean in adverse shooting conditions.

^{* The structure is designed to be dust- and splash-resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.}

Petal-type hood

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