Dolly zoom is a camera effect that involves either pushing the camera in towards the actions while zooming out, or pulling the camera back while zooming in. The result is that the foreground remains unchanged, while the background seems to grow or shrink in proportion. The most famous (and first) example was in Alfred Hitchcock's Vertigo (1958).
It is known by many other names, including "Vertigo zoom", "contra-zoom", "trombone shot" etc.
