Key Features

1. Constant F2.8 Aperture Across a Versatile 28-105mm Zoom
The SIGMA 28-105mm F2.8 DG DN | Art lens offers a constant F2.8 aperture throughout its entire zoom range, unlike many conventional zoom lenses that typically drop to F4 at the long end. This lens provides exceptional light-gathering and depth-of-field control across all focal lengths, delivering superior optical performance by effectively minimizing optical aberrations within each lens group. Additionally, its excellent close-focusing capability allows for macro-style results when zoomed in, making it versatile for various photography styles.

Ideal for Portraits and Low-Light Photography
The fast F2.8 aperture across the entire focal range makes the SIGMA 28-105mm F2.8 DG DN | Art a versatile lens suitable for a wide range of photography, from wide-angle landscapes to dimly lit street scenes. At longer focal lengths like 85mm and 105mm, the F2.8 aperture creates a shallow depth-of-field, isolating subjects beautifully against large, soft bokeh, making it perfect for portraits.

Superb Close-Up Performance
With a minimum focus distance of just 40cm across the entire zoom range, this lens can capture detailed, close-up shots, especially at its 105mm setting. The resulting maximum magnification ratio of 1:3.1 offers powerful macro-style imagery.

Superior Optical Performance Across All Ranges
The SIGMA 28-105mm F2.8 DG DN | Art maintains high optical performance throughout its zoom and focus range by effectively suppressing aberrations. This consistency is achieved through a premium optical design featuring two FLD, one SLD, and five aspherical elements, including a large-diameter φ66.4mm element, made possible by SIGMA’s advanced manufacturing technology in Aizu, Japan.

Designed to Minimize Flare and Ghosting
Advanced simulation technology and SIGMA’s Nano Porous Coating and Super Multi-Layer Coating work together to significantly reduce flare and ghosting, ensuring rich, high-contrast images in any lighting condition.

Minimal Focus Breathing
Designed with filmmakers in mind, this lens minimizes focus breathing, reducing angle-of-view changes during focus shifts. This ensures smooth focus transitions when recording video and makes image alignment easier when focus stacking.

2. Superb Portability at Less Than 1kg
The SIGMA 28-105mm F2.8 DG DN | Art is designed for portability, weighing less than 1kg, making it ideal for all-day handheld shooting. The use of five aspherical elements in the optical design helps to shorten the overall length of the lens, while a magnesium-alloy construction around the mount contributes to its lightweight build without sacrificing durability.

Compact Design with Exceptional Performance
Despite its compact size, the lens delivers excellent optical performance, thanks to continuous technological innovation and cutting-edge manufacturing processes at SIGMA’s facility in Aizu, Japan.

Smarter Design for Lower Weight
The lens's design and materials have been optimized to achieve a remarkably light weight, with the use of magnesium-alloy around the lens mount reducing the weight by two-thirds compared to aluminum, all while maintaining rigidity.

3. Professional Features, Fast AF, and Excellent Build Quality
The SIGMA 28-105mm F2.8 DG DN | Art offers fast and accurate autofocus, thanks to its linear motor HLA (High-response Linear Actuator), along with a range of professional features that ensure the best results in any shooting situation. These include a dust- and splash-resistant structure, a water- and oil-repellent coating, a zoom lock switch, a de-clickable aperture ring, AFL buttons, and a smooth manual focus ring.

Rapid and Accurate AF with HLA Motor
The lens is equipped with a linear motor HLA, delivering fast, precise, and smooth autofocus. Its quiet operation also makes it ideal for noise-sensitive video recording.

Enhanced Ergonomics with Aperture Ring
The lens features a dedicated aperture ring for quick exposure adjustments, with an aperture ring click switch useful for filmmakers and a lock switch to prevent accidental changes.

Customizable AFL Buttons
Two customizable AFL buttons, located on the side and top of the barrel, can be easily accessed in both horizontal and vertical shooting positions, enhancing ergonomic handling.

Zoom Lock Switch for Secure Handling
The zoom lock switch holds the zoom mechanism in place at its wide end, preventing unintentional extension when carried. The lock can be quickly released by the switch or by turning the zoom ring, allowing for a more flexible workflow.

Weather-Resistant Design for Tough Conditions
The lens features a dust- and splash-resistant structure, with a water- and oil-repellent coating on the front element to keep it clean during adverse conditions.

Included Petal-Type Hood
A dedicated petal-shaped hood is included, featuring a locking mechanism for secure attachment.
