Dolly Zoom in Blender

The Dolly Zoom, also known as the Hitchcock shot, the Vertigo shot, the Jaws effect, or the Zolly shot is a disorientating effect used in filmography. The effect is achieved by zooming a zoom lens to adjust the angle of view (often referred to as field of view, or FOV) while the camera dollies (moves) toward or away from the subject in such a way as to keep the subject the same size in the frame throughout. In its classic form, the camera angle is pulled away from a subject while the lens zooms in, or vice versa. Thus, during the zoom, there is a continuous perspective distortion, the most directly noticeable feature being that the background appears to change size relative to the subject. -Wikipedia This Blender quick tip demonstrates how you can achieve this effect easily in Blender.
