come very close in almost all cases to the MTF charts Zeiss provides. That is important because Cosina made all those Zeiss lenses in the same factory that they make the Voigtlander lenses, and as the Zeiss lens' MTF provided by Zeiss are claimed to be actual lenses tested in the factory, the Voigtlander lenses may well be similarly tested.
If you look at those Zeiss lenses and all the Sony FE lenses they tested reported on this page:
How many of the 36 lenses tested had a smaller drop from their center performance to their outer performance? The answer is 3 and it is notable what these three lenses are: the ZEISS Milvus 35 f/1.4, the Zeiss 100 f/2 Makro, and the Zeiss Otus 28 f/1.4. All are very large and expensive lenses. None of the 22 Sony FE mount lenses tested at that point had less of a drop of center to edge performance.
You might ask what lens' MTF charts look most like the one Voigtlander posted for the 90 f/4 APO Lanthar? Check it out but it is the Sony FE 135 f/2, the Zeiss Batis 135 f/2.8 APO, the Zeiss Otus 85 f/1.4 (although it has a larger mid zone dip), and the Zeiss 85 f/2.4 Loxia (although the Voigtlander is a bit higher performance everywhere). That is some pretty good company for this new lens to keep.
