5. Chromatic aberration

In the case of such a fast zoom lens chromatic aberration correction is not an easy thing at all. The Olympus optics constructors faced a difficult task. Their performance can be assessed by looking at the graph below.

Once again it would be difficult to have any serious reservations. In fact we can notice chromatic aberration only for the maximum relative aperture in the 35-65 mm focal range. Even there the level above 0.10% we consider to be medium. On slight stopping down or using 100 mm focal length the aberration decreases to low or momentarily even negligible values. Such a performance can get only a positive assessment.

The fact that very similar graphs we’ve got for other 70-200 mm f/2.8 lenses is very interesting. In their cases the aberration was the highest at shorter focal lengths and decreased on stopping down; it was also the lowest at the maximum focal length and increased on stopping down for a change.
