Unless you are doing engineering, architectural or product design work, chances are you will never need the isometric camera.
Removing perspective (or vanishing point) is important in communicating the relative dimensions and proportions of an object. Since the perspective will change based on the "virtual" lens focal length, it becomes more difficult to understand the design when mixing renderings produced with varying focal lengths.
So, eliminating perspective allows for some consistency in visual communication. |
