7. Coma, astigmatism and bokeh

The coma is corrected very well. Some slight deformations of the circular shape of the diode are visible only in the very corner of full frame but that effect is slight, not able to influence our high assessment in this category.

You can describe the astigmatism correction in very similar terms. An average difference between horizontal and vertical MTF50 function values was just 2.2% which is a brilliant result. A round of applause!

We don’t have any reservations concerning the appearance of defocused light points. The light in circles is spread very evenly, you can’t notice any concentric rings or local extremes. Defocused images, provided by the Zeiss, should be very pleasing to the eye.
