Superb portability
Standard zoom lenses are expected to be compact and lightweight for comfortable all-day handheld use. The SIGMA 28-105mm F2.8 DG DN | Art is crafted with this in mind. It incorporates five aspherical elements to reduce the total length and features a magnesium-alloy construction near the mount, ensuring the lens weighs under 1kg. This design achieves excellent portability akin to shorter standard zoom lenses, yet offers an extended zoom range.
Packed full of features
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.
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.
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.
Customise your experience
Located on the side and on top of the barrel, two customisable* AFL buttons can easily be reached in either horizontal or vertical shooting positions, ensuring more ergonomic handling. The lens also features a dedicated AF/MF switch and aperture ring click switch, a useful tool for film-makers, and a lock switch that helps ensure the aperture ring is not knocked out of its setting accidentally.
* Assignment of functions is limited to supported cameras and assignable functions vary depending on the camera.
HLA focusing motor
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.
