Canon EF 35mm f/1.4 L II corners vs Sigma AF 35mm f/1.4 Art corners
#2
1st of all, "20mp" is false. Not sure why PZ calls it "20mp" and not 21mp.

 

Other things to consider:

DXO is very, VERY unreliable. Look at the Canon Ef 17-40mm f4 L USM for instance: http://www.dxomark.com/Lenses/Canon/Cano...ments__795 Wow, amazing performance at 17mm and wide open, right?

 

On top of that, their field map is silly, they only have 4 test points per lens and the rest is just from interpolation and rotation.

 

PZ uses sharpening in their MTF evaluation. Sharpening will have more effect on certain frequencies than others, so some frequencies are preferred over others, making the cross sensor results a bit hard to judge. And obscures diffraction effects somewhat.

 

The digital picture crops feature has its very own issues. 

 

But apart from all that, consensus from less problematic comparisons seems to be that the Canon EF 35mm f1.4 L USM II performs noticably better than the Sigma in the borders/corners wide open, partly because of much better CA performance. And that the Sigma 35mm f1.4 Art anyway can be called a sharp lens.
