Sigma professional 70-200mm f/2.8 for Canon EF with APO correction and HSM autofocus.
The Sigma 70-200mm f/2.8 EX DG APO Macro HSM is a fast professional telephoto zoom for Canon EF mount with constant f/2.8 aperture, APO correction, and macro close-focus capability. The HSM motor delivers fast, quiet autofocus, and the EX build quality provides professional-grade construction at a fraction of Canon's own 70-200mm f/2.8 pricing.
Optical quality is very good with the APO glass elements delivering excellent colour correction and sharpness across the zoom range. The constant f/2.8 provides consistent depth-of-field control and low-light capability. The macro mode enables close focusing that adds versatility beyond standard telephoto zoom applications.
Build quality follows Sigma's EX premium tier with a robust metal barrel, smooth zoom and focus rings, and professional-grade construction. The HSM motor enables full-time manual focus override during AF operation. The lens includes a tripod collar for stable mounting, essential for professional telephoto zoom work.
On the used market, the Sigma 70-200mm f/2.8 EX APO offers professional-grade telephoto zoom capability at very competitive prices. For Canon shooters wanting constant f/2.8 speed with quality optics without the Canon L-series price premium, it provides excellent performance and value.
