Definition for Zoom Shot
From Biology Forums Dictionary
1) Technically not a moving shot because the camera itself does not move, the zoom is made by the zoom lens, which has variable focal length. The zoom became a popular technique in the Sixties. On screen a zoom-in resembles a dolly-in, but its telephoto optics as it moves in on the subject differ from the more realistic, dynamic look that a dolly or hand-held shot retains.
2) A shot taken with a zoom lens in which the focal length of the lens changes from wide angle to long focus or the reverse so that the camera seems to move in to (i.e., "zoom in" to) or away from (i.e., "zoom out" from) the subject while the camera actually remains stationary.]
