Sigma 18-35mm f/1.8 DC HSM Art Lens for Canon EF

The Sigma 18-35mm f/1.8 DC HSM Art is an ultra-fast standard zoom lens designed for APS-C-format Canon EF-mount DSLRs (providing a 28.8-56mm equivalent focal length range). Renowned as the first zoom lens to achieve a bright, constant f/1.8 maximum aperture, it offers exceptional low-light performance and precise shallow depth-of-field control throughout its focal range. As part of Sigma’s high-performance Art series, it incorporates five Special Low Dispersion (SLD) glass elements and four aspherical elements to minimize chromatic aberrations and distortions. An integrated Hyper Sonic Motor (HSM) delivers fast, quiet autofocus with full-time manual focus override, while the internal focus and zoom design maintain a consistent barrel length during operation.
