The shots on citizen kane required a small aperture - if you knew anything about photograpy you would know that a small aperture requires lots of light and a very slow shutter-speed. You couldn’t use a slow shutterspeed if you were using a hand-held device because there would be “camera-shake”. While the steadicam eliminates much of the “camera-shake”, it is still an inadequate device for shooting scenes that require a lot of depth-of-field. I would imagine that as technology increases in the realm of image-stabilization the dolly and the steadicam will be no longer necessary.
