Voigtlander Nokton 58 mm f/1.4 SL II
7. Coma and astigmatism
The crops below show that the Voigtlander is unfortunately closer to the Zeiss than to the Sigma here. Even 20 years ago showing a Sigma as an example to a Zeiss and a Voigtlander would be tantamount to heresy. Times change though and our crops speak for themselves.

Fortunately the Voigtlander 1.4/58 corrects the astigmatism well. It is superior here even to its 40 mm focal length brother which dealt poorly with this aberration near the maximum aperture. In the case of the 1.4/58 model the average difference between horizontal and vertical MTF50 function values reached 5% which is a very good result when it comes to lenses of such parameters.
