Sigma 28-105mm f/2.8 DG DN Art Overview

Precise Focusing, Exceptional Convenience
Flexing a vast zoom range and a fast constant aperture, the 28-105mm f/2.8 DG DN Art Lens from Sigma covers a variety of popular focal lengths, equipping you to capture everything from sweeping landscapes to intimate portraits all with one lens. Designed for L-Mount-mount full-frame mirrorless camera systems, this lens provides a minimum focusing distance of 15.8″ across the entire zoom, ensuring your ability to capture detailed close-ups of your subjects. Driven by an HLA motor, this lens delivers quiet and precise autofocusing, and its rounded 12-blade diaphragm ensures pleasing and circular bokeh. This lens repels damage from outside elements by coupling a water- and oil-repellant front lens element coating with a dust- and splash-resistant design.
