And, if you used an infinite zoom macro lens on a subject infinitely far away, it would not have perspective at all but instead appear as an isometric view. Where does one find an infinitely large lens? Don't worry, you can't afford it anyway. It costs infinite money. Jokes aside, the math on this really works out. Orthogonal projection is the limit as d tends to infinity of perspective projection.
