5. Chromatic aberration

Let’s start with the longitudinal chromatic aberration. In fast lenses it might be a problem as you can find out reading our test of the Nikkor AF-S 85 mm f/1.4G or the Canon EF 24 mm f/1.4L II USM. Have a look at our photo of the autofocus accuracy test chart, used by us also to assess the longitudinal chromatic aberration performance.

As you see, despite applying the extreme value of f/0.95 the image doesn’t feature any out-of-focus colour cast which means the longitudinal aberration is corrected splendidly.

The same can be said about the lateral chromatic aberration – you can assess it glancing at the graph below.

The values of the lateral chromatic aberration range from a bit over 0.02% to a tad more than 0.04%. It is a negligible level so this aberration shouldn’t worry us at all.
