Precision Focus, Unmatched Versatility
The Sigma 28-105mm f/2.8 DG DN Art Lens offers an expansive zoom range paired with a fast, constant f/2.8 aperture, making it ideal for everything from sweeping landscapes to detailed portraits—all with a single lens. Designed for Sony E-mount full-frame mirrorless cameras, it features a minimum focusing distance of just 15.8 inches throughout the entire zoom range, allowing for stunning close-up shots. The lens is powered by a high-response linear actuator (HLA) motor for fast, quiet, and accurate autofocus, while a 12-blade rounded diaphragm delivers smooth, circular bokeh. Built for real-world shooting conditions, it includes a dust- and splash-resistant construction along with a front element coated to repel water and oil.
