The coma correction also falls short of our expectations. At the maximum relative aperture it is very distinct and it doesn’t disappear even on stopping down to f/4.0. In these both cases the level of this aberration is even higher than that of the 20 mm lens.

Nikon Nikkor AF 24 mm f/2.8D - Coma and astigmatism

Fortunately in the case of astigmatism the situation is better. Here the difference between horizontal and vertical MTF50 function value, measured in the frame centre, reached just 4.4% which is a result befitting a good prime instrument.
