I think what thrice says makes sense, at least to me
We always get confused by scientific definitions, but in practical terms, if you stand at the same camera to subject distance (no matter if close or far), and shoot with a WA, standard, and tele, the perspective is different, unless you crop, which I suppose no one wants to normally do.
Hmm, I am not sure what you are getting at either If you stand in one place, and shoot with 3 lenses, you do indeed get exactly the same photo, with extra around it, the wider the lens. The central parts are the same.
But I thought Daniel was talking about varying the subject distance to keep the main subject the same size (a boulder, say), and observing the relative sizes of the objects in the scene. The thing is that if you put your eye where the lens is, you will always see the same as the lens sees, no matter what focal length (except fisheyes, and ignoring other kinds of distortion).
And that is the normal state of things. The camera *of course* makes a photo of what you see, with the same proportions. What else could it do?
