6. Distortion

24-25 mm fixed focal length lenses usually show barrel distortion reaching even −2%. The Zeiss Distagon T* 25 mm f/2.0 ZE/ZF.2 was a good example of that tendency; even on the APS-C sensor its distortion amounted to −1.11% and it increased to −1.96% on full frame.

Compared to that the results of the Batis 2/25 are looking very well because on the smaller sensor we got −0.68%, and on the bigger one +0.06%. If those values look strange at first glance you have to know they are a result of moustache distortion featured by the tested lens. On the APS-C detector you see just slight barrel distortion but on full frame the lines bend the other way so the averaged out results across the whole area provide values close to zero.

On the one hand you can complain about the moustache distortion Zeiss employed here but on the other hand it is so slight that almost imperceptible. It means your photos most likely will be devoid of any geometric deformations.
