5. Chromatic aberration

From the following chart we can deduce at once that the horizontal chromatic aberration takes a significant part in worsening of the image quality at the edge of the field of view. In fact for the whole spectrum of, very wide after all, apertures and focal lengths it ranges from 0.09% to 0.14% so can be placed at the medium level.
