Sigma’s superfast standard zoom for Super35
Posted on Jun 17, 2025 by Adam Duckworth
With an f/1.8 aperture, the Sigma 17-40mm zoom for APS-C mirrorless cameras pushes the boundaries
The Sigma 17-40mm f/1.8 DC Art builds upon the groundbreaking innovations of the Sigma 18-35mm f/1.8 DC HSM Art, which earned high acclaim as the world’s first f/1.8 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.
The Sigma 17-40mm f/1.8 DC Art has the convenience of a zoom lens with a constant aperture of f/1.8 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.
The zoom range of the Sigma 17-40mm has been expanded from its predecessor the Sigma 18-35mm f/1.8, 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 aperture while freely framing their shots without the need to change lenses.
The on-sale date will be the 10 July with the exception of the Canon RF version, which will be August. Price is £779/ $919.
