Does the “Lens Focal Length Conversion Factor” of 1.6 affect perspective?
Perspective has to do with the placement of the camera in relation to the subject. Different focal lengths do effect perspective, but only indirectly. A wide angle lens, for example, lets you exaggerate perspective by getting in close and still keeping everything you desire in the field of view. Aside from this, though, focal length doesn’t effect perspective. Let’s take a hypothetical situation where you take a shot with a 20mm lens and then with a 200mm lens, while keeping the camera completely stationary between the two shots. If you were to then crop down the 20mm shot such that it had the same field of view as the 200mm lens, you would find that the two images would have exactly the same perspective.
