This is kind of odd...Spielberg moves the camera a great deal but David Fincher is widely known to use many, many lock-downs and he never does unmotivated camera movement and rarely ever uses a Steadicam. There are, in my opinion, major differences between Spielberg and Fincher. Fincher's style seems to descend much more from Polanski and that crowd than from Spielberg. Fincher has also talked many times on his commentaries about avoiding close ups and preferring to show entire rooms or spaces. He only uses a close up if there's something very important he wants to point out...whereas Spielberg uses close ups a lot.
