REVIEW: Sigma 80-400mm f/4.5-5.6 EX APO OS DG

6 November 2003
  • Conclusion: This lens produced excellent results at the short end of the zoom range and acceptable ones at the longer end. The OS system worked well, if a little obviously and, like it’s competitors, took a moment to kick in accurately. Once working, it showed well in the viewfinder and gave confidence in using it. The build quality is excellent with a clean matt black finish that is known to be hard wearing and no unwanted play in any of the moving parts.
  • Pros: Good build and finish, Excellent at the shorter focal lengths (and not too bad at full stretch), OS system works well, Good close focus ability for type.
  • Cons: Some drop off in resolution at longer length., Large foot doesn’t have Sigma’s excellent QR system., A little heavier than the opposition

Sigma AF 80-400mm f/4.5-5.6 EX APO OS - Review / Test Report

15 January 2004
  • Conclusion: The Sigma AF 80-400mm f/4.5-5.6 EX OS is an impressive piece of equipment. In terms of build quality Sigma seems to have catched up with the genuine brand offerings. Nonetheless the lens didn't convince completely. In the lab the sheer quality figures are surely good enough with slightly better MTF results than the Canon EF 100-400mm f/4.5-5.6 USM L IS but in the field the OS didn't really feel as reassuring or mature (or I had too much coffee at the time ...).
