Here I have taken several shots using the exact same framing on a face with different focal length.
For me the most natural and closest to the subject’s true features is the second image (f5.3 75mm). The images either side are acceptable, although the face appears too thin in the first image. The two latter images distort the facial features – nose is bulbous and the face is elongated. I note that the facial lines are ironed out in the closer shots too (of course this could be viewed as an advantage!).
