7. Coma, astigmatism and bokeh

The influence of the coma is clearly noticeable at the maximum relative aperture. Still that aberration’s level is hardly huge; we would describe it rather as being on a border between medium and high levels. After stopping down to f/4.0 it becomes low.

The tested lens doesn’t have any astigmatism correction problems. An average difference between horizontal and vertical MTF50 values amounted to just 3.4% and such a result we consider low.

We don’t have any reservations concerning the appearance of defocused light circles in the centre. The only thing that drew our attention was the noticeable rim near the very edge. Inside the circle the light is spread evenly and we didn’t observe any noticeable local extremes. In the corner of the frame the circles are deformed distinctly, not only due to vignetting but mainly because of the shape changes connected to a perfect distortion correction.
