Rumor: Alpha to E-mount adapter with translucent mirror and phase detection AF
 

" According to my very best sources Sony is ready to launch a special Alpha to E-mount adapter with built-in translucent mirror and phase detection AF system!!! This means you can transform every NEX camera in a perfect A-mount compatible system!

Something similar has been made by Leica with the Visoflex. The electronic viewfinder is not included on the adapter (you can attach it separately on the hotshoe). I don’t know the price yet, but it will definitely be much more expensive than the current simple Sony Alpha LAEA1 Alpha to E-mount adapter."
