I am wondering why they just don't use the lame trick of making the lenses longer - thus increasing the flange distance i.e. essentially providing a DSLR lens in a native mirrorless lens body. It feels as if Fuji is going that way to some degree - their lenses are comparatively big. I haven't verified this regarding their designs though.

 

Seems as if at least Sony is purposely sacrificing quality for smaller size/weight (in the APS-C league) - possibly in order to kill MFT from a paper spec perspective. This feels as if driven by marketing, less so engineering though.
