Sigma's non-OS 70-200mm f/2.8 for Canon — the EX DG HSM version without stabilisation.
The Sigma 70-200mm f/2.8 EX DG HSM for Canon EF is the Canon mount version of Sigma's non-stabilised constant aperture telephoto zoom. The constant f/2.8 provides professional speed. HSM motor provides fast, quiet AF. DG coatings optimise for digital sensors. Described in multiple other mount versions across earlier IDs.
Optical performance is good. Centre sharpness is very good from f/2.8. The constant aperture provides consistent exposure and DOF. HSM motor is fast and quiet. No image stabilisation — the main limitation versus the Canon EF 70-200mm f/2.8L IS. Tripod collar included. APO elements control chromatic aberration on some versions.
Canon EF mount. Filter thread is 77mm. Weight is approximately 1,370 grams. Build quality is solid EX professional. No image stabilisation — Canon's L IS version has this advantage. The lack of IS keeps the used price very low. Best for well-lit situations where IS is less critical.
Available at very low prices — the lack of IS drives demand down. Check AF and smooth zoom. A functional constant f/2.8 telephoto at bargain pricing. The Canon 70-200mm f/2.8L IS or Tamron 70-200mm f/2.8 VC are preferred for stabilisation. Best for tripod/monopod work or well-lit sports and events.
