Olympus Zuiko Digital ED 12-60 mm f/2.8-4.0 SWD

5. Chromatic aberration

The presence of many low-dispersion elements certainly helped the Olympus to achieve the result, which can be admired on the graph below.

In the beginning and the middle of the focal range the chromatic aberration won’t disturb us in practically any conditions. Its level is low or negligible for most of the cases. The biggest chances to notice this aberration we have at the maximum relative aperture and maximum focal length because the level of 0.12% we define as medium. On stopping down by one stop, though, we make the aberration decrease to the level below 0.09% so a value on the low and medium border.

In this category you can hardly find anything to complain about.
