See: http://www.sonyalpharumors.com/sr5-sony-nex-goes-full-frame/
But considering the really limited lens lineup of the original E-mount lenses, not even to mention FF, what's the point?
The most ridiculous thing, on the other hand in the Pentaxland, is that there are so many old original K-mount lenses out there but there is not a FF Pentax body!
So, if old Pentaxians are to get the new NEX, must they go down the "adapting" route?
