Ooze, that's my conclusion as well after having owned waaaay too many lenses.

An interesting thing though, is that Zeiss actually measures MTF from real lenses, when most other manufacturers are
calculating MTF based on the design of the lens. Needless to say, the latter will give more spectacular curves, but won't tell the truth.
Even rigorous testing cannot tell everything about a lens from everyones perspective. For example, the MTF charts are almost always representing only
one distance, which often is a short one. But even CA, SA, vignetting, field curvature, bokeh and everything else needs to be looked at from the buyers perspective. – How do you use the lens? At what apertures? In what lighting conditions? At what distances? And so on.
My best advice is to try out the lens for yourself, if there is a possibility. After having owned ~50 Nikkors I tried the ZF 35/2 out of curiosity, and I was blown away. Yes, now I'm a "Zeiss fanboy", but I wasn't then.
But again, the 50/1.4 is not for everyone. That lens and the 85/1.4 is probably the ones in the Z* line that is causing the worst trouble for people, with focus shift and softness at some circumstances where other much cheaper 50:s are way better.
To much talk now! Can you resist it?
