Sigma 28-105mm F2.8 DG DN Art Lens for L-Mount in More Detail

F/2.8 aperture for low light and portraits

With its fast maximum f/2.8 aperture throughout the entire focal range, the Sigma 28-105mm F2.8 DG DN | Art is a highly versatile lens that suits a variety of photography styles. Whether you prefer capturing wide-angle landscapes, low-light city shots, or stunning portraits with beautiful foreground / background separation, this lens handles it all.

The constant f/2.8 aperture is especially beneficial when shooting handheld in low-light conditions, allowing you to keep your shutter speed up without sacrificing image quality. At longer focal lengths, such as 85mm and 105mm, this wide aperture creates a shallow depth-of-field that makes your subject pop against pleasingly soft bokeh backgrounds.

Constant aperture across a unique 28-105mm zoom range

Unlike many zoom lenses that tend to narrow their aperture as you zoom in, the SIGMA 28-105mm F2.8 DG DN | Art maintains a constant F2.8 across the entire zoom range. This means you get the same excellent light-gathering and depth-of-field control whether you're shooting at 28mm or 105mm. The lens excels in optical performance, thanks to its meticulous suppression of aberrations throughout the lens groups. This level of precision ensures consistently sharp and clear images, no matter the zoom setting.

Superb close-up performance

Getting close to your subject is easy with this lens, as it offers a minimum focus distance of just 40cm across the zoom range. This makes it ideal for capturing fine details and textures, and filling the frame with your subject for impactful close-ups. At 105mm, this close focus results in impressive macro-style images, bringing out more details in your subjects, with a maximum magnification ratio of 1:3.1.

Superior optical performance

This lens doesn’t compromise on optical quality, keeping aberrations in check throughout its entire zoom and focus range. This is achieved through Sigma’s premium Art-Series optical design of 18 elements in 13 groups that includes two FLD, one SLD, and five aspherical elements.

Minimises flare and ghosting

Flare and ghosting are minimised through advanced simulation technology, ensuring that your images retain rich contrast and vibrant colours in all shooting conditions. Sigma has also applied exclusive Nano Porous and Super Multi-Layer Coatings to further reduce unwanted artefacts, which is particularly noticeable when shooting backlit subjects.

Minimal focus breathing

For filmmakers, the Sigma 28-105mm F2.8 DG DN is designed to minimise focus breathing, keeping changes to the angle-of-view due to focus shifts to a minimum. This ensures smoother focus pulls and consistent framing when shooting video, and it also makes image alignment easier when focus stacking, which is an essential tool for many landscape photographers.

Under 1kg weight for superb portability

The Sigma 28-105mm f/2.8 DG DN Art Lens is designed with portability in mind, weighing in at less than 1kg. For a standard zoom, it’s important to be lightweight enough for all-day handheld use, and this meets that need well.

Excellent performance in a compact design

Sigma incorporated five aspherical elements into its design, effectively shortening the overall length while maintaining excellent optical performance. The lens also features a magnesium-alloy construction around the mount, which helps keep the weight down without sacrificing durability. This smart design approach allows the lens to offer superb portability similar to shorter standard zooms, while still providing an extensive zoom range.

The use of five aspherical elements in the optical design not only contributes to the lens’s compact size but also helps render high levels of sharpness. Achieving this balance of performance and portability was made possible by continuous innovation and the advanced manufacturing techniques at Sigma’s primary production base in Aizu, Japan.

Professional features, fast AF and excellent build quality

With an Art-Series model users can expect a lens packed with professional features, fast autofocus, and solid build quality. To meet these demands it includes a linear motor HLA (High-response Linear Actuator) that provides fast and precise autofocus, with quiet operation that’s perfect for video work.

It is also built to withstand tough conditions, featuring a dust and splash-resistant structure along with water and oil-repellent coatings for easier maintenance. For added convenience, it includes a zoom lock switch, a de-clickable aperture ring for silent exposure changes, AFL buttons, and a focus ring, making manual focus and other settings really easy to handle.

Dedicated de-clickable aperture ring

A dedicated aperture ring on the lens allows for quick exposure adjustments, offering a more tactile and traditional shooting experience, which many creators prefer. The aperture ring click switch is particularly useful for filmmakers, and a lock switch is also available, which prevents accidental changes to your settings.

Customisable AFL buttons

In support of quicker workflows and customisation, the lens features two AFL buttons, one on the side and one on the top of the barrel, which are easily accessible whether shooting in landscape or portrait orientation. These can be customised depending on your camera, giving you more control over your shooting experience and streamlining common functionality usually controlled by the camera body.

Zoom lock switch

A zoom lock switch keeps the zoom mechanism securely in place at its wide end, preventing unwanted extension when carrying the lens. You can unlock it either by using the switch or simply by turning the zoom ring, allowing for a quicker workflow, which is similar to the 24-70mm lens’ functionality.

Weather-resistant design

The lens is designed for outdoor use, with dust and splash-resistant build to keep contaminants out, though it’s important to note that it’s not completely waterproof. The front element is also treated with a water and oil-repellent coating to help keep it clean and free from dust and smears.

Additionally, the lens comes with a dedicated petal-shaped hood that includes a locking mechanism for secure attachment, providing extra protection and reducing lens flare.
