Sigma 28-45mm F1.8 Maximum Aperture DG DN Art Lens with Internal Zoom and HLA Autofocus (L Mount)

The Sigma 28-45mm F1.8 DG DN Art Lens (L Mount) is the world’s first full-frame zoom lens with a constant maximum aperture of F1.8, offering outstanding optical performance comparable to prime lenses. Designed for both photographers and filmmakers, it features a robust construction with a dust- and splash-resistant body, internal zoom for consistent length during operation, and a lightweight build under 1kg. Its advanced optical design includes 3 aspherical and 5 SLD elements that effectively suppress chromatic aberrations, reduce flare and ghosting with Nano Porous and Super Multi-Layer coatings, and deliver stunning clarity and bokeh across all lighting conditions. The lens maintains a close focusing distance of 30cm throughout the zoom range with a 1:4 magnification ratio at the telephoto end, making it perfect for tight spaces and close-up work. Its HLA (High-response Linear Actuator) autofocus system ensures fast, near-silent focusing, while the bi-wire manual focus ring offers customizable rotation and precise control. Ideal for video as well, it suppresses focus breathing and supports smooth focus pulls. Additional features include a lockable aperture ring, a click/de-click switch, and a reversible petal-type lens hood, making this lens a powerful and versatile tool for professionals seeking both flexibility and exceptional image quality.
