I think the Dolly Zoom is the most common usage
The focus has to change for this, though. You're changing the focal length, counteracting this by changing the position of the camera, and you have to change focus wrt to the camera to keep the subject in focus. Or do I misunderstand the procedure or did I misunderstand you here?
