Why doesn't Sony use smaller sensor surface advantage from NEX system to build f/1.2 35mm lens,  and 85mm f/1.4?

Person is taking photos, not camera. When photograph is bad, it's because photographer doesn't know how to choose settings optimal to "own preferences". Then blames camera for bad IQ.
This is same as blaming car about arriving to wrong destination.

BEcause of

A-Target Audience

B-Real advantage not worth it.

A-The target audience of APS-C and DT lenses is consumer photographers. Not P&S, but not Advance amateurs or pros. A 1.2 lens would mean an expensive (and big) lens, and wont sell many of those.

B-In reality, a 1.2 isnt giving 1 stop of light compared to a 1.8. IT is giving less. This is the nature of digital sensors. The bigger the sensor, the more they can get from a 1.2. The smaller, the less. So, in fact, sony is not making not even 1.2 for FF. They are making 1.4 for FF, and 1.8 for DT/aps-c lenses.

even fuji recognizes it, point 2:
