If you read the full text of the review, the Sigma and Canon lenses test equal up by f/2.8. The Sigma is only better at f/1.4 and f/2.0.
They equal up but only against Roger's copy of the very best Canon 35L he has tested (out of 100 copies of lens or so). Or did I read this wrong?
Stopped down to f/2.0 and f/2.8 respectively, the Sigma responds with 900/770/560 and 1000/870/770 mtf50 values (center/average/corner). The Canon ‘best copy’ returned 840/740/520 and 1000/840/740 numbers. It’s probably worth mentioning the Sigma has slightly less distortion at 1%, too.
I wonder if my 35L even goes to f/2.8? Never tried that one before...
