Unlike many of the new Zeiss Milvus lenses, this model has a new optical design. The difference between the Zeiss Milvus 85mm f/1.4 and the previous version of this lens is dramatic! Nicely done, Zeiss!

Another comparison that warrants discussion is the Zeiss Milvus 85mm f/1.4 vs. Zeiss Otus 85mm f/1.4 lens. The Otus retains the lead in center of the frame performance, but ... the Milvus is sharper in the corners. Adding support to these results is the MTF comparison between these lenses. This performance combined with a price tag that is far less than half of the Otus is going drive popularity of this Milvus lens model.
