Sample movie filmed with the Sony Alpha NEX-7. This video is part of my Sony NEX-7 review at Camera Labs. With a little fiddling around you can get the NEX-7 to 'pull' focus by switching between manual and AF operation during shooting. But it's nowhere near as easy or sure-footed as touch-screen focussing.
