Olympus Zuiko Digital 35-100 mm f/2.0
5. Chromatic aberration
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.
