the 70-300 is of particular interest. They have changed the optical formula from the Sony 70-300mm F/4.5-5.6 G SSM:

The MFTs look good too:

And to stop some people from blathering about "FE mount lenses being just SLR designs with inbuilt rear adapter... blah blah". The "Internet wise men" tried that with the 35/1.4 FE even though the cutaway shown by Sony had clearly shown this as false.

Incidentally, the 50/1.8 FE is probably a reused SLR design - sort of a cross between the Canon's and Nikon's recent 50/1.8 lenses. But I thought that's it.
