5. Chromatic and spherical aberration


Chromatic aberration

The longitudinal chromatic aberration is not bothersome in the case of the tested lens. The colouring of off-focus images even near the maximum aperture is slight – you really don’t have to worry about it.

The lateral chromatic aberration is decently corrected because the results range from 0.08 to less than 0.11%. Such values, being on the borderline between low and moderate level, are no reason to complain.

Spherical aberration

The tested lens has no problems with correcting the spherical aberration – there is no „focus shift” effect and no characteristic „mist” at the maximum relative aperture. Also the photos of a diode, positioned in front of and behind the focus, are proof of it.

The light spread in the circles is more or less even, without any local extremes.
