Nikon Nikkor AF 80-200 mm f/2.8D ED

7. Coma and astigmatism

The coma is corrected perfectly in our tested lens. In the pictures with the diode in the center and in the corner of the frame we cannot see any difference and the diode’s picture is almost identical in all the cases. The Nikkor deserves nothing but applause!

Nikon Nikkor AF 80-200 mm f/2.8D ED - Coma and astigmatism

If not coma and chromatic aberration then maybe the astigmatism causes the weaker performance in the maximum aperture area. According to our test results this hypothesis seems to be the most probable since the average difference between the horizontal and vertical MTF50 function values in our tested lens is 15%, which is a little bit of a disappointing result in this class of equipment. By comparison, the Sigma 70-200 f/2.8 had a result of 2.5% in this category.
