5. Chromatic aberration

It is really an interesting thing: although the resolution was improved and the construction of the lens - changed, the chromatic aberration graphs remained the same as it was in the case of this lens’s predecessor; momentarily they even got worse. For instance at 18 mm in both cases we have the aberration increase corresponding the increase of the aperture but in the case of the old “kit” it ranges from 0.06 to 0.13% and in the case of the new one -from 0.09 to 0.16%. Such values are nothing to be ignored because we will notice this kind of aberration in a picture for sure.

Fortunately the situation improves at longer focal lengths where the aberration level should be rather unobtrusive.

For form’s sake it’s worth adding that the Nikkor’s aberration is also the lowest at 18 mm and it also increases with the increase of the aperture but it doesn’t exceed the level of 0.11%. The Nikkor clearly prevails over the Canon in this category.
