This is actually not distortion in the actual sense, it is just perspective. Super wide angle lenses have this and is just optics.icarus said:#4 in that gallery has terrible distortion. What settings did you use?
Our eyes sees it this way too but our brains manage to correct it into an in our eyes 'correct' perspective.....When you don't hold your lens straight (levelled) you will get this effect of tall subjects 'falling' backwards, or things in the corners being 'stretched'.
Whatever lens you have (the best Nikon or Zeiss or third party lens) they all have this effect in different strength (depending on the focal length), so it has nothing to do with settings, or quality of the lens
