Not content with its NEX updates, Sony has also updated the Alpha range to bring its translucent mirror technology to the top of the range. The 24.3-megapixel A77 and A65 both draw on the sensor from the NEX-7 but, with a mirror and phase detection autofocus, can shoot at rates usually reserved for full-frame cameras. By not having to wait for the mirror to clear, the A65 and A77 shoot at 10 frames and 12 frames per second respectively, even with full-time autofocus.
