5. Chromatic aberration

The improvement doesn’t end here. The chromatic aberration has also been lowered at practically every focal length. In the case of the older “kit” it reached even 0.16% at the widest angle; now it decreases to 0.14%. Previously, in the middle of the range, it was on the 0.07% level; now it doesn’t exceed 0.05%. We see a similar decrease for the longest focal length as well.

Overall, the lens’s performance should be praised. In the 35-55 mm range the chromatic aberration won’t disturb us at all. We also won’t have any problems at 18 mm, providing that we don’t stop down the lens significantly. If we do so, though, the aberration will become clearly visible reaching the medium and high values border.
