Yes, I understand that, and that is exactly the point. Photography Step 1 (for me at least) is to find the exact camera locations, or perspective(s), desired. Step 2 is to frame and crop exactly as desired in-camera using a good zoom. Assuming you don't have a prime lens of the exact needed focal length, the only choices are to move from your desired location (perspective) or crop in PP, neither very satisfactory to me.
I apologize. It sounded like you indicated one would change perspective by zooming to a different field of view - which, of course, does not happen.
