Optical lens manufacturer - Perspective distortion of telephoto lens
In fact, as the subject gets farther away, the perspective distortion will become smaller and smaller, but it will become flat, that is, lose the level and detail. Two subjects far apart appear to be one on top of the other. This is a kind of reverse distortion, which often occurs when shooting with a telephoto lens. Because the subject is very far away from the camera, a flat perspective effect is produced.
Why is this often seen in photos taken with a telephoto lens? This is because when using a telephoto lens, the shooting distance is often more distant. In fact, whatever lens is used at the same distance will produce this distortion.
