Sigma 28-45mm F1.8 DG DN ART SE

Redefining the Zoom Lens: World's First F1.8 Full-Frame Zoom

The Sigma 28-45mm F1.8 DG DN Art breaks new ground as the first full-frame zoom lens to offer a constant F1.8 aperture. Designed for the Sony E-mount, this lens provides the flexibility of a zoom with the light-gathering power and shallow depth-of-field typically reserved for high-end prime lenses. Weighing less than 1kg, it is a portable powerhouse for both handheld photography and professional gimbal setups.

Unrivaled Optical Performance

Engineered with 18 elements in 15 groups, including five SLD and three aspherical elements, this lens meticulously corrects aberrations. The result is edge-to-edge sharpness that rivals prime lenses. Advanced Nano Porous and Super Multi-Layer Coatings significantly reduce flare and ghosting, ensuring high-contrast images even in challenging backlit conditions.

Optimized for Video and Gimbals

The inner zoom mechanism ensures the lens length remains constant, maintaining a stable center of gravity perfect for gimbal work. Filmmakers will appreciate the suppressed focus breathing and the high-speed HLA (High-response Linear Actuator) motor, which delivers silent, precise autofocus for smooth transitions and natural focus pulls.

Professional Build and Ergonomics

Despite its fast aperture, the lens remains durable and weather-resistant. It features a dust- and splash-resistant structure with a water-repellent front coating. Tactile controls include two customizable AFL buttons, a dedicated aperture ring with a de-click switch, and a lockable petal-type hood, providing a seamless workflow for professionals in the field.
