Fast Sigma f/2.8 standard zoom for Canon APS-C with macro and HSM autofocus.
The Sigma 18-50mm f/2.8 EX DC Macro HSM is a fast standard zoom for Canon EF-S mount APS-C cameras, offering a constant f/2.8 aperture with macro close-focus capability. The HSM autofocus motor provides fast, quiet focusing, and the EX build quality delivers a premium feel above consumer-grade alternatives.
Optical quality is good with sharp centre performance and the constant f/2.8 providing consistent depth-of-field control across the useful 29-80mm equivalent range. The macro capability enables close-up photography without a dedicated macro lens. The aspherical elements help control aberrations for improved image quality throughout the range.
Build quality follows Sigma's EX standard with a robust barrel, smooth zoom and focus rings, and quality that inspires confidence during daily use. The lens is compact for a constant f/2.8 zoom, keeping it manageable on smaller Canon APS-C bodies. The HSM motor enables full-time manual focus override during AF operation.
