5. Chromatic and spherical aberration

Chromatic aberration

The Voigtlander fully deserves APO letters in its name. Even at the maximum relative aperture it would be difficult to notice any traces of longitudinal chromatic aberration.

The graph below allows us to assess the correction of the lateral version of that aberration.

Once again the tested lens can only be praised. The aberration level is the highest at the maximum relative aperture but even then it doesn’t exceed 0.04%, remaining very low. On stopping down the aperture the results are kept around a level of just a tad less than 0.02%. The degree of correction is excellent indeed. .

Spherical aberration

First photos of this chapter don’t feature any ‘focus shift’ effect. Additionally, when you consult defocused circles of light created in front of and behind the focus, you won’t notice anything disturbing either. These facts allow us to say that the tested lens doesn’t have any noticeable problems with spherical aberration.
