Dxomark posted a double Sony related testing:
1) Best lenses for the Sony A77 (Click here to read). As expected most of the times Zeiss lenses are on top :)
2) NEX-5T sensor text (Click here to read). They write: “It’s human nature to feel disappointed that Sony didn’t improve the sensor between this and the NEX-5R but the few improvements in features over that model are welcome nonetheless.“
