5. Chromatic aberration

As you can notice while consulting a photo of the autofocus testing chart, presented in chapter 10, the lens doesn’t show any noticeable longitudinal chromatic aberration. The lateral aberration is quite another story – at shorter focal lengths it is clearly visible.

At 18-30 mm focal lengths the aberration near the maximum relative aperture is still medium on slight stopping down. Near f/11- 16 it becomes high, though. At the maximum focal length we see that trend reversing. Near the maximum relative aperture the level of that aberration is medium and on stopping down it decreases to low. Once again the overall performance of the EF-S 18–55 mm f/3.5–5.6 IS II is similar to the performance of its predecessor.

Looking closer at some details you can see that the tested model features higher aberration especially in the middle of the focal lengths range. This fact can be explained by the quality dispersion and also by the change of the testing body (smaller pixels with different layout of microlenses can show the aberration in a different way) but the most probable reason here is a slight change of focal length. The predecessor was tested at 35 mm and here we used 30 mm.

To sum up the results shown in this category don’t allow us to say that the new lens optically differs in anything from its predecessor.
