Tested on the Canon 5D Mark III, the EF 35mm f/1.4L II USM Lens gets 33 points DxOMark lens score and it has a great performance. According to the test results, Canon EF 35mm f/1.4L II doesn’t perform as well as the Sigma 35mm f/1.4 Art in sharpness. However the EF 35mm f/1.4L II USM Lens performs better than Sigma 35mm f/1.4 Art and Zeiss 35mm f/1.4 Distagon.
From DxOMark conclusion:
With the introduction of high-resolution bodies such as the Canon EOS 5Ds and 5Ds R, with their ability to highlight lens flaws, it comes as little surprise to see Canon roll out new versions of some of the older models in their line-up. The original 35mm f/1.4 wasn’t a bad performer, but it was beginning to show its age. The new model greatly surpasses the original in several key areas. It is generally sharper, but it’s the improvement in geometry and uniformity that really impresses. Not only does it have low field curvature and astigmatism, but Canon has also dramatically lowered lateral chromatic aberration, with the overall effect of greatly improving imaging performance in the outer field (where the older model was weak). The new Canon even outperforms the highly-regarded Sigma for uniformity at wider apertures — however, the Sigma remains much more accessible. At $1799, the Canon certainly isn’t cheap, but over the long term it should prove to be a good value.
