The 35 mm focal length provides an angle of view of almost 64 degrees; with such a value some lenses can show quite noticeable barrel distortion. It's enough you remind yourself that the Sigma c 2/35 had distortion of −1.94% on full frame, the Samyang FE 1.8/35 could get to −1.58%, and the Nikkor Z 1.8/35 had a result of −1.28%.
Compared to that the results of the Voigtlander look really well. On the smaller APS-C sensor deformations can only be called negligible with a result of −0.39%,. After passing to full frame that value changes to −0.55% so it still remains very low. You can say without doubts that the constructors of the Voigtlander optics actively control distortion, without counting on any help from software of the camera. A round of applause!
