Sigma 17-40mm f1.8 DC Art
The Sigma 17-40mm F1.8 DC | Art builds upon the ground-breaking innovations of the Sigma 18-35mm F1.8 DC HSM | Art, which earned high acclaim as the world’s first F1.8 zoom lens in the photography and video industry. Thirteen years after its debut, this next-generation lens achieves not only superior optical performance but also a wider focal length of 17-40mm while reducing its weight by over 30%. This dramatically enhances the versatility of a large aperture standard zoom lens.
In addition to the fast and quiet autofocus driven by the HLA (High-response Linear Actuator), the lens incorporates an inner zoom mechanism and minimal focus breathing, ensuring outstanding performance for both still photography and video production. Sigma, the pioneer that stunned the world with the first-ever F1.8 zoom lens, has once again revolutionized the history of large aperture zoom lenses with ground-breaking advancements.
Descriptive power comparable to a prime lens
The Sigma 17-40mm F1.8 DC | Art has the convenience of a zoom lens with a constant aperture of F1.8 throughout the zoom range. Taking advantage of a large aperture comparable to a prime lens, the lens is suitable for low-light environments such as indoor and night scenes, as well as for expression using large bokeh.
Excellent optical performance
The optical design, realized through the latest design and processing technologies, including the use of high-precision aspherical lenses, achieves excellent optical performance.
By emphasizing the correction of axial chromatic aberration and sagittal coma flare, the lens achieves high resolution even at the wide-open F1.8 aperture, rendering delicate textures and fine details with stunning clarity.
Flexible framing made possible
The zoom range of the Sigma 17-40mm F1.8 DC | Art has been expanded from its predecessor the Sigma 18-35mm F1.8 DC HSM | Art, covering 25.5-60mm in 35mm format*. From wide-angle tabletop photography to portraits that fully utilize the telephoto angle of view, users can take full advantage of the expressive power of the large F1.8 aperture while freely framing their shots without the need to change lenses.
Dust- and splash-resistant structure* and water-repellent coating
In addition to a dust- and splash-resistant structure, the frontmost surface of the lens has a water- and oil-repellent coating applied, so that the lens can be used safely even in harsh outdoor environments.
* The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable.
