7. Coma, astigmatism and bokeh

The Olympus 3.5/30 definitely doesn’t correct coma in a perfect way. That aberration can be spotted at the maximum relative aperture and even on stopping down the lens by 1 EV it still remains visible. In that category the Olympus fares worse than the Panasonic 2.8/30 Macro.

The astigmatism, understood as an average difference between horizontal and vertical MTF50 function values amounted to 4.8%. It is a result slightly better than the result of the Panasonic 2.8/30 Macro for a change.

Circles of light we got in out-of-focus areas look moderately well. You can see a lighter rim everywhere and light spread inside the circle is not perfectly even. You should expect a better performance from a fixed focus lens so it is a reason to complain a bit.
