5. Chromatic and spherical aberration

Chromatic aberration

Photos below prove the tested lens doesn’t have any serious problems concerning the longitudinal chromatic aberration. A slight colouring of out-of-focus images is visible but only slightly. It would be difficult to notice in real life photos.

Now let’s check the performance concerning the lateral chromatic aberration – graphs below present the results of the Canon 24-105 mm II respectively on the edge of the APS-C sensor and on the edge of full frame.

At both ends of the range of focal legths you see the highest level of that aberration, with results amounting to 0.08–0.09%. Still such a level should be considered slight. In the middle of the range of focal lengths there are no chromatic aberration problems whatsoever.

In this category the new Canon prevailed over its rivals. The older version of that lens could get as high as over 0.14%; the Sigma 24-105 mm OS had a level of aberration close to 0.16% and the worst results belong to the cheaper Canon 24-105 mm STM as they oscillated near 0.12%.

Spherical aberration

First photos of this chapter don’t show any ‘focus shift’ effect. Circles of light we got in front of and behind the focus aren’t identical but the differences between them can hardly be called huge. It seems spherical aberration problems of the tested lens are smaller than those of the Canon EF 24-105 mm STM or the Sigma 24-105 mm OS.
