Sigma 28-45mm f/1.8 DG DN Art Lens for Sony E

The Sigma 28-45mm f/1.8 DG DN Art lens for Sony E is the world's first full-frame zoom lens with a constant f/1.8 aperture throughout the entire zoom range — a genuine milestone in optical engineering. Designed for Sony FE-mount mirrorless cameras, it delivers prime-level sharpness and bokeh across a versatile wide-to-normal range, making it the ideal single lens for wedding, portrait, event, and video photography. With an internal zoom design, suppressed focus breathing, and a linear actuator AF motor, it's equally at home on a gimbal as it is in the studio.
