However I disagree your conclusion that Sigma 35/1.4 Art @F1.4 is sharper than 35/2.0 IS @F2.0. You might have a soft copy.
I don't dispute that as a possibility.
DPR 35/2.0 @F2.0 IS vs 35/1.4 A @F1.4 on 5D2
DPR 35/2.0 IS @F2.0 vs 35/1.4 A @F1.4 on 7D
TDP 35/2.0 IS @F2.0 vs 35/1.4 Art @F1.4
In either case, it shows 35/2.0 @F2.0 is sharper than Sigma 35/1.4 Art @F1.4. At F2.0, Sigma is sharper. Canon captures up at F2.8 and as sharp as if not slightly sharper at F4.0.
Also, I was playing with the 35 IS about an hour ago and adjusted the AFMA another 2 notches because of the indoor light. I've found that I can have some fairly wild variations for AFMA depending on the light source. I've had swings as high as 7 (+16 down to +9 for the 85/1.8) when changing light sources. So it's quite possible the softness I'm seeing is AFMA related in various light sources and I'm not correcting for it.
Now that I've sold the 35 ART, I can't shoot them side by side to test for sharpness. However, I looked back at a particular picture that I felt was REALLY sharp at f/1.4 just a few minutes ago because I took an almost identical picture with the Canon 35 IS this morning and what I saw was what you demonstrated via links and also attest to my quote (in red) above; I didn't have it AFMA'd quite right and the lighting source makes a difference. I processed the images similarly and found that at f/2, the Canon 35mm f/2 IS is sharper than the Sigma at f/1.4 - no doubt about it.
Thanks for pointing that out and leading me to question my results! I wish I could edit my review... :-/

It’s too much of a cliché, too inappropriately dismissive, too likely to be tossed in as an ad hominem attack by someone who shows signs of extreme fanboyism himself."
In other words - takes one to know one. And you lack creativity.
