Sigma 28-45mm f/1.8 DG DN Art Lens (L-Mount)

The Sigma 28-45mm f/1.8 DG DN Art Lens redefines versatility as the world's first zoom lens for full-frame mirrorless cameras maintaining f/1.8 throughout its entire range. Combining prime-like sharpness with video-optimized engineering, this lens delivers professional-grade performance while keeping your kit compact and balanced. The wide-to-normal focal range eliminates the need for multiple lenses, letting you travel lighter without compromising image quality or creative control.

Design and Performance

Featuring 18 elements in 15 groups, the lens includes 3 aspherical and 5 SLD elements to reduce flare and ghosting while minimizing aberrations. This ensures superior optical performance compared to other Sigma Art lenses, including primes. The rounded 11-blade diaphragm further enhances sharpness and produces a large, smooth bokeh at wide open aperture. With a minimum focusing distance of 30cm and a maximum magnification ratio of 1:4, this lens provides increased depth of field and versatility, making it ideal for close-up shots in tight spaces.

Video Production

Crafted specifically for video production, the lens features a high aperture of f/1.8 and a zoom range from wide to normal, allowing for multi-functional use in single-shooter and run-and-gun scenarios. The internal zoom design maintains its overall length during operation, providing easy balance when mounted on gimbals. Additionally, the design effectively eliminates focus breathing, ensuring seamless movement through the focal range. Sigma's lightning-fast, responsive linear actuator autofocus maintains its quiet and precise performance, while click and lock mechanisms enhance manual focusing capabilities.
