Sigma 50 mm f/1.4 EX DG HSM

5. Chromatic aberration

The chart below shows that Sigma’s chromatic aberration depends only slightly on the aperture value and can be contained in the range from 0.11% to 0.13%, so its level is medium.

Sigma 50 mm f/1.4 EX DG HSM - Chromatic aberration

It’s a result significantly worse than the result of the Canon, which had values on the 0.08% level and lower. Nikkor also fared better than Sigma, although here the difference is really slight, because Nikkor presents the values from the 0.09-0.11 % range. In the case of the Sony we have a draw and the Pentax lens was worse than the Sigma.
