The 50mm is now a Distagon, and whilst it is not apochromatic, performance is significantly better than the double Gauss designs (used by pretty much everybody else, including the earlier Zeiss 1.4/50). Wide open resolution is much higher, peaking at f4-5.6. There remains some secondary longitudinal CA (‘bokeh fringing’) but correcting this would require apochromatic correction and increase cost significantly. It is one third the price of the Otus 55, but achieves 90% of the performance.

The 85mm is even closer: it carries almost the same optical design as the Otus 85, but minus one aspherical element. Again, this results in some secondary LoCA, lower apochromatic performance and slightly lower micro contrast at wide apertures, but an unexpected benefit. The drawing style is somewhat smoother than the very ‘crisp’ Otus 85 and the fully spherical design means very smooth bokeh without any texture in highlights – this is the one limitation of the Otus 85, and actually a reason to own one for portraits and other similar subject even if you have the Otus. I would say it reaches 95% of the Otus’ performance. Unfortunately, physics dictates performance comes with weight: both are still heavy. Both lenses have remarkable flare and contrast performance thanks to the new coatings: they are very flare resistant and maintain great performance even shooting against the sun. 

간단 요약 Milvus 50mm f1.4는 오투스 50mm f1.4의 90% 성능이고 Milvus 85mm f1.4는 오투스 85mm f1.4의 95% 성능이다.
