Building on the success of the original Sigma ART 18-35mm lens, the worldÕs first f/1.8 zoom lens, the Sigma 17-40mm f1.8 DC Art delivers a wider field of view with improved optical performance. It is also more portable than the pioneering 18-35mm model, weighing 30% less, making it a great choice for everyday photography and travel. With a constant f/1.8 maximum aperture across the full zoom range, this Sigma lens is ideal for low-light shooting and versatile depth of field control. Its splash- and dust-resistant construction, along with a water- and oil-repellent coating, makes it a reliable option for shooting on the move.

The Sigma 17-40mm f1.8 DC Art lens is designed for outstanding image quality, using advanced design and manufacturing technologies, including high-precision aspherical lens elements. Its optical design focuses on correcting axial chromatic aberration and sagittal coma flare, producing exceptional resolution and beautifully rendered fine detail, even at the maximum f/1.8 aperture. Advanced simulation technology and SigmaÕs proprietary Super Multi-Layer Coating also help suppress flare and ghosting, delivering rich contrast and consistent results across a wide range of shooting conditions.

For added flexibility, the lens includes two customisable AFL buttons, positioned on the side and top for easy access in both landscape and portrait orientation. Each button can be assigned a function through the camera menu, giving you greater control while shooting.

The Sigma 17-40mm f1.8 DC Art is also well suited to video production. It features a High-response Linear Actuator (HLA) for fast, quiet and highly precise autofocus, making it ideal for stills, gimbal use and vlogging. The lens is also engineered to minimise focus breathing, helping maintain a consistent angle of view during focus changes for smoother, more natural focus pulls. For convenient handling, it includes an aperture ring that can be de-clicked for silent aperture adjustments during video recording, plus an aperture ring lock switch to help prevent accidental changes to your settings.
