Sigma 28-105mm f/2.8 DG DN Art Lens (Sony E)

OVERVIEW

Harness the power of this versatile and portable F2.8 optic with an extended 28-105mm focal range – a standard zoom that goes well beyond standard.

The SIGMA 28-105mm F2.8 DG DN | Art is not just another standard zoom lens. With a powerful wide-angle to medium telephoto focal length and a bright F2.8 aperture throughout, this full-frame mirrorless zoom combines outstanding optical performance, superb build quality and a range of pro-grade features to make it one of the most versatile optics on the market for mirrorless systems.

The lens is built to tackle a huge range of subjects and situations, from expansive low-light landscapes to portraits with big, beautiful bokeh, and thanks to SIGMA’s latest optical technology and the use of large diameter elements including FLD, SLD and five aspherical elements, it is able to do so with superb clarity and sharpness. This allows the lens to deliver exceptional versatility without compromising on optical quality. The lens also includes high-speed AF with HLA technology, a rugged dust- and splash-resistant structure, and various functions such as an aperture ring, all packed into a compact and lightweight body weighing less than 1kg, making it an exceptional all-round choice for both stills and video.

Surprisingly compact, full-frame, wide-angle to telephoto zoom lens with a fast constant aperture. 

Featuring HLA (High-response Linear Actuator) autofocus, and optical performance that lives up to the standard of Art line lenses, the SIGMA 28-105mm F2.8 DG DN | Art joins SIGMA’s lineup of fast-aperture zoom lenses in the Art line, offering photographers and videographers a variety of premium standard zoom options depending on their personal style.

Includes a lockable aperture ring with click/declick function, as well as two AFL buttons and a zoom lock switch.

A minimum focusing distance of 15.8 inches (40cm) at all focal lengths, and maximum magnification ratio of 1:3.1 at the telephoto end add to the versatility of this new zoom lens.

Measures have been taken to minimize changes in optical performance due to differences in zoom and focus positions, including the use of a difficult-to-process large-diameter FLD glass in the first group to suppress aberrations in each group. In addition, the use of 5 aspherical lens elements has enabled the lens to achieve both a wide zoom range of 28mm to 105mm and a large aperture of F2.8, while reducing its overall size.

By thoroughly reducing the weight of each part, the lens is kept under 2 pounds while achieving both a wide zoom range and an F2.8 aperture. The lens barrel near the mount is made of magnesium rather than aluminum, ensuring rigidity while reducing the weight of these parts alone by two-thirds.

The dust- and splash-resistant design and water-and oil-repellant coating on the front element also makes it suitable for shooting both stills and video in inclement weather.
