It seems like there is a deliberate plan behind these all; supported by Sony as well as Zeiss too. I do not believe any company would invest such huge amounts of money and efforts to come up with two hi-tech bodies to perform great with the majority of the wider portion of available rangefinder lenses. I do not believe Sony engineers who created some finest sensors in the last couple of years have fallen short in supplying a proper IR filter on top of the sensor like the ones on the Leica M (or M9) or lacking technology to come up with offset microlenses aligned (or configured) optimally; I do not believe they wanted these at all. Why would they? An AF lens in average costs about one third or half of a body, constituting almost a camera price for an average user having two-three lenses, why would they kill the possibility of making the same revenue twice and amortise their investment in shorter time (also before Canon or Nikon come up with something similar, who knows..)
We saw the same movie with the introduction of X-trans sensor too; on which only their native lenses performed flawlessly despite of the smaller sensor size; make the sensor-covering layers 2.5mm thick to sell your own wides. The remarkable point with the optical designers at Fujifilm or Zeiss, they know how to come up with some splendid lenses by overcoming the "handicaps" they created with their own hands; Fujifilm wides work better than anything else on X-trans sensors, the new FE 55mm and 35mm Sonnars are stellar lenses; we already started seeing how they perform against the best lenses available from any brand on any body no matter what they cost.
I tend to believe more on a sophisticated plan "devised" by Sony-Zeiss collaboration to define a new standard for top-class short-register mounts. IMHO, we are going to see some more short FLs from this collaboration to be regarded as being the reference-class. If I would be investing some $100M's to develop some innovative bodies to sell around for $2K, then I would rather find a way to sell my own lenses as well.... specifically my own lenses..
The new trend seems to be custom designed lenses for custom designed sensors; specific formulas, specific software methods. Leica have been doing this since years, now the others will follow the example... Fujifilm first, then Sony.. perhaps in 2014 Nikon or Canon?
