Here there are practically no problems at all. At the maximum relative aperture brightness loss in frame corners amounts to just 15% (-0.46 EV) and it decreases to an imperceptible level of 9% (-0.26 EV) and 2% (-0.05 EV) on stopping down the aperture to f/8.0 and f/11.0 respectively.

This time the results are higher but, for mirrorless standards, still completely acceptable. By f/6.3 brightness loss in frame corners amounts to 29% (−1.01 EV), by f/8.0 it decreases to 20% (−0.64 EV), and by f/11.0 it drops to 12% (−0.38 EV). Any possible problems end completely by f/16.0 and f/22.0, where we got the following results: 6% (−0.17 EV) and 3% (−0.10 EV).
