Exactly.
The functionality of zoom and FOV are closely related.
zoom affect its fov in a perspective camera.
see https://github.com/mrdoob/three.js/blob/7a62164566e030611c0e4c92e9747bc005cdab26/src/cameras/PerspectiveCamera.js#L217

Use zoom instead, which works in both perspective and orthographic.

If you wish to compute the final FOV, please check below.
