7. Coma, astigmatism and bokeh

We don’t have any reservations concerning the coma correction. The situation is perhaps not perfect because the image of a diode in a frame corner is slightly distorted but, fortunately, that effect is not huge, not deserving any serious criticism.

An average difference between horizontal and vertical MTF50 function values amounted to 8% so the astigmatism in the tested lens can be called moderate.

Defocused light circles don’t look very interesting, though - you can notice distinct local extremes and deformations. Still you should remember that it is not a kind of lens you’d use to generate soft blur and paper-thin depth of field.
