Sigma 17-40mm f/1.8 DC Art Lens - L-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-C mirrorless 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 | 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.
