I read that thread, but no one really had a really good explanation of why FF is needed.

Need is relative - FF offers the following advantages

  • About 1.5 stops noise
  • Large optical viewfinder
  • Unique lens options (although adding a speed booster fixes some of this if you have mirrorless. But not with useful AF or optical finder.)
The FF cameras from Canon/Nikon are mature, well tested, and comprehensive systems (example: flash capability )  Why would they go away?  

The only recurring answer that seems to be consistent is the need of extreme dof. Really? Can a sensor format be really be sustained by the demands of dof alone?

Sony/Minolta made the 135mm STF, Nikon makes the 105 and 135mm defocus control lenses, and both Canon and Nikon make 200mm f/2 lenses.  Obviously, there is some demand for extreme DOF.

The STF (and Nikon's DC lenses) have more to do with the rendering of OOF areas than to help achieve extreme DoF. For example, for a similar composition, 85mm f/1.4 probably provides a shallower DoF on FF than 135mm f/2.8 does.
