7. Coma, astigmatism and bokeh

The coma seems to get bigger with the increase of the focal length. In the 12-25 mm range it remains low although at 25 mm it’s a bit higher than at 12 mm or so it seems. At the maximum focal length the coma spreads its wings, seriously limiting the image quality on the edge of the frame.

The astigmatism doesn’t cause any serious problems. The average difference between horizontal and vertical MTF50 values amounted to 5.3% which we consider to be a low result.

Defocused light points don’t look well. You can find many local extremes so the blur won’t look particularly attractive.
