Impossible to do a simple zoom? i just want to do a zoom ,a real zoom , not a FOV adjustement

similar like using your scrollwheel when your are inside of a camera , but with the whole camera , so the border would just adjust depending of the zoom 

is it possible to do so inside of blender ?
There are three things people may call "zoom" for a CGI camera :


Focal length
Sensor size
Camera position (dolly zoom)
