Overview

The Sigma 28-105mm F2.8 DG DN | Art lens offers a versatile focal range with a constant f/2.8 aperture, making it ideal for events, portraits, and weddings. It sacrifices 4mm on the wide end compared to 24-105mm lenses but gains a stop of light. Optically, it delivers excellent sharpness and good flare resistance, though some ghosting may occur. Build quality is rugged with weather sealing, a smooth aperture ring, and fast HLA autofocus, but lacks optical stabilization. At $1499, it's a more affordable alternative to the Canon 24-105mm F2.8.
