I am not sure what you are referring to ...
If you take the border numbers of the Zeiss at f/1.8, you have to stop down the Fuji beyond f/4 to match this.
The Zeiss is also sharper in the image center at f/2.2 than the Fuji at f/2.8.
MTF-wise the Zeiss is superior to the Fuji till f/5.6. At f/8 and f/11 the Fuji has a marginal advantage.
