A rumor reported at Nokishita suggests Zeiss will soon release a Zeiss Otus 100mm f/1,4 lens. The announcement should happen before Photokina 2018.
The Zeiss Otus 100mm f/1.4 has an APO Sonnar design, and is said to have already undergone field testing. It will come four Canon and Nikon mounts (sorry Sony folks). Filter diameter is 86mm.
Zeiss Otus lenses are a lot of things but not inexpensive, so expect the Zeiss Otus 100mm f/1,4 to be in the same price range as its siblings.
