Ronkonkoma, NY—The Sigma 28-105mm F2.8 DG DN | Art lens for full-frame mirrorless cameras provides many popular focal lengths in a single fast-aperture zoom lens. The compact, wide-angle to telephoto lens is available for the Sony E mount as well as the L mount. It features HLA (high-response linear actuator) autofocus as well as Sigma’s Art line optical performance.
Further, the new lens includes a lockable aperture ring with a click/de-click function, two customizable AFL buttons, a focus mode switch and a zoom lock switch. Additionally, the dust- and splash-resistant design and water-and oil-repellent coating on the front element make it suitable for shooting both stills and video in inclement weather. The lens is a solution for expansive low-light landscapes and street photography to portraits with beautiful bokeh. 
Sigma 28-105mm F2.8 DG DN Art Key Features
- Constant f/2.8 aperture across a versatile 28–105mm zoom range for light-gathering and depth-of-field benefits across its focal range
- A minimum focusing distance of 15.8 inches at all focal lengths as well as a max magnification ratio of 1:3.1 at the telephoto end for macro-style results
