Sigma's early EX 70-200mm f/2.8 for Canon — the non-OS version with APO macro capability.
The Sigma 70-200mm f/2.8 EX APO DG Macro for Canon EF is an early non-stabilised version of Sigma's constant-aperture telephoto zoom. The APO designation indicates apochromatic elements. The Macro suffix indicates closer-than-normal minimum focusing. This is the Canon mount version of a lens family also described in other mounts across earlier IDs.
Optical performance is good for the era. Centre sharpness is very good from f/2.8 with the APO elements controlling chromatic aberration well. The Macro designation allows closer focusing than standard 70-200mm zooms. Bokeh is smooth. The lack of OS stabilisation is the main limitation compared to later versions and competitors.
Canon EF mount. Filter thread is 77mm. Weight is approximately 1,370 grams — heavy. Build quality is solid with the EX professional designation. HSM motor provides fast, quiet AF. No image stabilisation. A tripod collar is included. The Canon EF 70-200mm f/2.8L IS is the main competitor with stabilisation advantage.
Available at very low used prices — the lack of OS and newer alternatives have driven demand down. Check AF accuracy and smooth zoom. Best for well-lit conditions where the constant f/2.8 is more important than stabilisation. The Sigma 70-200mm f/2.8 Sports is the dramatically improved successor.
