In Blender, from the object data tab for the camera we can change:

focal length/fov & sensor width/height

but when we scroll the mouse wheel in the camera view, we zoom in/out on that camera view. When we do this, I don't see the focal length/fov parameter get updated in the camera's object data tab. So which camera parameter are we updating when we scroll the middle mouse button in the camera view? Thanks.

    $\begingroup$ Those parameters are valid only for the rendered picture, and the mouse scroll's zoom doesn't affect it. $\endgroup$ – FFeller Jul 16 at 18:58
