Optical Zoom

Optical zoom is used to change frame area coverage and image size during forward and reverse zooming action in order to: produce a dramatic or impact effect (according to speed of the move); counteract or add to the speed and motion of camera zooms or dolly shots; re-frame by enlargement and /or add footage to either end of camera zooms or dolly shots by extending the range of moves; momentarily eliminate unwanted areas or objects by zooming forward and back at specific footage points (such as when a microphone or lamp is accidentally framed in during part of a scene); add optical zoom to static scene to match camera zoom or dolly in a superimposure. The out-of-focus zoom also is effective to depict delirium, blindness, retrospect, transition, etc.
