5. Chromatic and spherical aberration

Chromatic aberration

The longitudinal chromatic aberration is not high. You might try and notice it at the maximum relative aperture but even then it remains low. What’s more, it disappears completely on stopping down the lens to f/2.8.

You can describe the lateral chromatic aberration in similar terms – the graph below presents the performance of the lens in this category, depending on the aperture value you employ.

As you see that aberration never exceeds 0.03% so it is negligible and won’t be seen in real life photos. A round of applause!

Spherical aberration

The tested lens didn’t have any „focus shift” effect so the spherical aberration seems to be corrected at least satisfactorily. The appearance of defocused light points also don’t make us worry: the differences between images we created in front of and behind the focal point are slight. Overall we haven’t noticed any problems in this category.
