7. Coma, astigmatism and bokeh

The coma correction is definitely not a strong point of the Fujinon 2/35. You can notice that aberration without any problems at the maximum relative aperture; what’s more its level remains significant even after stopping down the aperture to f/2.8. It certainly contributes to the worsening of the image quality on the edge of the frame.

The astigmatism, understood as an average difference between horizontal and vertical MTF50 function values, amounts to 2.7%. It is a low level so the performance in this category should be assessed in a positive way.

Defocused light circles look very well with very even light spread; as a result blur areas will be pleasing to the eye. Our reservations concern only their truncation due to mechanical vignetting – that effect is visible even on stopping down the lens to f/4.0.
