Overview
The Sigma 28-45mm f/1.8 DG DN Art Lens for Sony E mount is a full-frame zoom lens with a bright f/1.8 aperture, delivering prime-like optical performance across its wide-to-normal focal range. It is ideal for photographers and videographers who want a compact, high-quality lens for travel, portraits, landscapes, and run-and-gun video setups.
Its optical construction reduces flare, ghosting, and chromatic aberrations using aspherical and Special Low Dispersion elements. The 11-blade rounded diaphragm produces smooth, natural bokeh while maintaining sharpness across the frame even at maximum aperture.
Designed for video, the lens keeps its length constant during zooming, suppresses focus breathing, and balances well on gimbals. High-speed linear autofocus is precise and quiet, while manual focus features adjustable linear and non-linear modes for intuitive operation. Coatings and a weather-resistant design ensure reliability in challenging shooting conditions.
