A constant F2.8 aperture

The SIGMA 28-105mm F2.8 DG DN | Art lens, with its fast aperture throughout the entire zoom range, is a versatile workhorse suitable for virtually all types of photography.

Landscape photographers can capture expansive scenes even in low light, thanks to the F2.8 aperture, which also excels for twilight cityscapes. The mid-range focal lengths are perfect for dimly lit documentary and street photography, offering shutter speeds a full stop faster than similar lenses. For portraits, the longer focal lengths of 85mm and 105mm, paired with the F2.8 aperture, create a shallow depth-of-field that beautifully isolates the subject against a backdrop of smooth bokeh.

Fill the frame with superb close-up performance

The lens has excellent close-up capability with a minimum focusing distance of 17cm at the wide end and a maximum magnification ratio of 1:2.7. This is useful when composing close-up shots of a subject, or when shooting in locations where space is limited.

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.

• Precision brass mount with seal: Protects against dust and moisture.
• Aperture ring: With a click/de-click switch and a lock switch.
• TSC construction: Made from a strong and light polycarbonate that behaves in a similar way to aluminium.
• Focus ring: A large, rubberised ring with a smooth action. Focusing is internal
• Petal-type lens hood: Cuts down on flare while limiting vignetting
• Focus Mode switch: For changing between AF and MF
• AFL button: Customisable depending on camera body
• Zoom lock switch: Locks the lens at 28mm to prevent unintended lens barrel movement
• Aperture Click switch: Clicks or de-clicks the aperture ring

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.
