The coma level also wasn’t altered. It is still visible for all focal lengths and it undoubtedly contributes to the decrease of image quality in the frame corners.

Astigmatism surprised us very nicely for a change. When it comes to plastics constructions, slacks, appearing even in new lenses, make this off-axis aberration increase sharply. Nikkor avoided that and in its case the astigmatism amounted to 6% which is considered a low level. How will the situation change in time and whether or not any slacks will appear – we don’t know. We are waiting for our Readers’ opinions in our base.
