A „fisheye” lens offers by definition this kind of projection that allows distortion to “revel” but, because of that, it gives us also a possibility to enjoy wide angles of view and interesting photographic effects. Speaking about high distortion in the case of a “fisheye” is nothing more than stating a construction fact. We might add, fulfilling our chronicle duty, that when we try to measure the distortion values using our programs we get results at the level of –50%.
