Loosely speaking, reducing the field of view will make the viewspace smaller, shrinking the camera frustum.

Explanation:
Reducing the field of view tightens the camera’s viewing cone. In a perspective projection, the size of what you can see at any given distance is tied to tan(FOV/2). When FOV gets smaller, tan(FOV/2) decreases, so the width and height of the frustum at every depth shrink. The near and far planes stay put, so the overall volume you can view becomes smaller, which is the zoom-in effect you’re familiar with. This is true for perspective cameras; in an orthographic setup, FOV doesn’t apply and you’d adjust a different parameter instead.
