A slight coma influence can be noticed even in the corner of the DX sensor. In the case of the full frame corner this influence is already distinct and clearly visible throughout the whole focal range, although the lowest at 120 mm.
In the case of astigmatism the results are definitely better. The average difference between horizontal and vertical MTF50 function values amounts to only 4.3% so it is low.
