The astigmatism, understood as an average difference between horizontal and vertical MTF50 function values, amounted to 6.3%. The Olympus fared better in this category for a change as in its case the astigmatism was 5%. Still both values are slight and there are no serious reasons to complain.

The circles of light we got in the blurred areas look nice - the light spread is even, without any local extremes. The tested lens should be only praised here.
