Some people believe that “perspective” in photography is determined by the focal length of the lens used. They will argue that certain focal lengths have a certain, inherent perspective or “look” that will be present irrespective of the size of the sensor. In other words, they will argue that a 135 mm lens will always give the “compressed” look one gets from using a telephoto lens, and a 28 mm lens will always give the “expanded” look of a wide-angle lens.
This is wrong. There is nothing special about the focal length. Perspective in a photograph is determined by one thing: the position of the photographer relative to the scene. (To be precise, perspective is determined by the distance from the front nodal point to the scene).
The reason people believe that a specific focal length effect a certain look is because the narrow FOV of a telephoto lens forces the photographer to take up a position far away from the scene, and the large FOV of a wide-angle lens allows the photographer to move closer. It is these differences in position, and not the focal length as such, that effect the difference in perspective.
It follows that as long as you stay in the same position, you get the same perspective no matter what focal length lens you put on the camera.
Below is a demonstration of this. It shows two photographs of the same scene. The first is taken with a 135 mm lens, the second with a 28 mm lens. The reason they show the same perspective is because the 28 mm lens is used on a camera with a much smaller sensor. The second photograph can be considered to be a 7.18 mm by 5.32 mm crop from the middle of a 36 mm by 24 mm film frame.
