How the projection center of a camera moves while zooming, when it is modeled as a pinhole camera?
Here's a common misunderstanding:
The projection center will be decided by this incidental FOV as in the picture.
Then the pinhole will move backward while zooming-in, just as the real zoom camera.

When it is zoomed in or out, the 'incidental' filed of view will change like this:
Then the pinhole will move backward while zooming-in, just as the real zoom camera.
