5. Chromatic and spherical aberration

Chromatic aberration

Looking at photos below you can notice slight colouring in areas far from the depth of field. Still the effect is hardly significant and shouldn't bother you in applications typical for the tested lens. In this category there is nothing to carp about.

Now let's check how lateral chromatic aberration depends on aperture value.

The relation is practically constant, with values keeping a level of 0.05%; it can be placed on the borderline of imperceptible and low areas. In this category the lens fares very well too.

Spherical aberration

First photos of this chapter don't show any significant 'focus shift' symptoms. Additionally the appearance of light circles before and behind the focus is almost identical. All of this allows us to think that spherical aberration is not a big problem for the tested lens.
