Product Details

Sigma 214965 ART 17-40mm F1.8 DC Lens for Sony E-Mount

With an F1.8 large aperture and exceptional image quality comparable to a prime lens across the entire zoom range, this zoom lens for APS-cCmirrorless cameras pushes the boundaries of still and video expression.

The Sigma 17-40mm F1.8 DC | Art builds upon the groundbreaking innovations of the Sigma 18-35mm F1.8 DC HSM I 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 pulling 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 groundbreaking advancements.

Features

Constant maximum aperture of F1.8

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.

* Approximately 27.2-64mm for the Canon RF Mount version.

Designed to minimize flare and ghosting
