Sigma 28-45mm f/1.8 DG DN: World’s First Full-Frame Zoom Lens with Constant f/1.8 Aperture

Photography enthusiasts and professionals, get ready to be amazed! Sigma has just unveiled a groundbreaking lens — the Sigma 28-45mm f/1.8 DG DN Art, the world’s first full-frame zoom lens with a constant f/1.8 aperture. This innovation sets a new benchmark in optical performance, especially for low-light shooters and video creators.

Designed for Sony E-mount and L-mount systems, this lens offers a unique focal length range of 28-45mm, making it perfect for both wide-angle shots and tight framing. With the constant f/1.8 aperture, users can achieve stunning background blur and exceptional low-light capabilities, something previously only possible with prime lenses.

This lens is built with 18 elements in 15 groups, including several high-precision glass components to reduce chromatic aberrations and enhance clarity. Autofocus is fast and silent, powered by a high-response linear motor — ideal for both photography and video work.

Despite its large aperture, Sigma has managed to keep the lens relatively compact and well-balanced, especially when paired with mirrorless bodies. The lens is also weather-sealed, ensuring durability in challenging conditions.

Content creators, event photographers, and cinematographers will particularly benefit from this lens. Its versatility, sharpness, and light-gathering capabilities make it a reliable tool for demanding creative environments.

Expected to launch in June 2025, the Sigma 28-45mm f/1.8 DG DN is priced competitively considering its unique features. Whether you’re shooting weddings, landscapes, or cinematic footage, this lens is set to revolutionize your toolkit.
