The SIGMA 28-105mm F2.8 DG DN Art, Sony-E mount, is not an ordinary standard zoom lens. With focal lengths from wide-angle to medium telephoto and a large aperture of F2.8 throughout the zoom range, this full-frame lens for mirrorless systems combines outstanding optical performance with excellent build quality and pro features. The lens is built to handle different subjects and situations, from grand landscapes in low light to portraits with big, beautiful bokeh. Thanks to SIGMA's latest optical technology and the use of large elements, including FLD, SLD and five aspherical elements, the lens delivers crystal clear images with outstanding sharpness.

Linear HLA motor for fast and accurate autofocus
The lens is equipped with a HLA (High-response Linear Actuator) linear motor that delivers maximum operating speed, ensuring responsive, precise and smooth autofocus. Thanks to silent operation, the motor is also ideal for video recording without disturbing noise.
Aperture ring with improved ergonomics
For quick exposure changes, or for a more traditional shooting style, the lens is equipped with a dedicated aperture ring that allows the user to change the aperture through the lens if desired. A click switch for the aperture ring is a useful tool for cinematographers, and a lock button helps prevent the aperture ring from being changed accidentally.
Two AFL buttons
The placement of two programmable AFL buttons, on the side and top of the lens barrel, makes them easily accessible in both horizontal and vertical shooting modes, providing improved ergonomics.
Aperture f/2.8 - Perfect for portraits and low light
With fast apertures throughout the focal length range, the SIGMA 28-105mm F2.8 DG DN Art is a true workhorse that can be used for almost any type of photography. Landscape photographers can take wide-angle shots of landscapes and use the F2.8 aperture for shooting low-light or cityscapes at dusk, while the middle focal lengths handle poorly lit documentary subjects and street photography, allowing shutter speeds that are a step faster than comparable lenses.
The popular portrait focal lengths 85mm and 105mm in combination with the maximum aperture of F2.8, provide a short depth of field that impressively isolates the subject against large and beautiful bokeh.
Superior optical performance throughout the zoom and focus range
SIGMA 28-105mm F2.8 DG DN | Art performs without compromise, effectively counteracting aberrations in every lens group and throughout the zoom and focal range. This ensures that the lens has a consistent performance even with such a long zoom range. This is possible thanks to the lens' advanced optical design, which includes two FLD, one SLD and five aspherical elements. The first group uses a large-format element of Ø66.4mm which is extremely difficult to produce and only possible thanks to SIGMA's advanced manufacturing technology at their production facility in Aizu, Japan.
Zoom lock
The lens is equipped with a zoom lock that holds the zoom mechanism in position at the widest focal length, preventing it from being accidentally shifted by its own weight when carried. The lock can be released with the switch or by turning the zoom ring for a faster and more flexible workflow.
Weatherproof construction for challenging conditions
The lens has a dust- and splash-proof construction that protects it against dirt and moisture in tough outdoor environments. The front lens is also coated with a water- and oil-resistant coating that helps keep it clean in difficult shooting conditions.
Smart design means less weight
F2.8 constant aperture zoom lenses can be heavy but by optimizing the design and materials of every part of the SIGMA 28-105mm F2.8 DG DN | Art, SIGMA has managed to achieve an impressively low weight of less than 1 kg. Using magnesium alloy instead of aluminum for the lens tube around the mount has reduced the weight of these parts by two-thirds, while maintaining rigidity.
Unique optical quality for a zoom lens
Thanks to unique construction with 5 SLD elements and 3 aspherical elements, aberrations are rigorously corrected. Axial chromatic aberration, which is particularly noticeable with large aperture lenses, is minimized and the lens produces clear images with minimal color cast, from sharply focused details to large, smooth bokeh.
Minimal focus breathing
The lens is essential for filmmakers who require consistent framing and has been designed to keep focus breathing to a minimum. This ensures that any changes to the angle of view due to focus drift are minimized across the entire zoom range, ensuring focus pull.
