Canon EF 70-200mm f/4L IS USM
5. Chromatic aberration
As long as we are not using the converter, there aren’t any problems with chromatic aberration. In this category, the lens behaves almost the same as the non-stabilization 70-200 f/4L model with a defect value of 0.04 to 0.08%.
The problem appears when we put the converter on. Then the aberration
increases to 0.11% and grows even further when stopping down the
lens. At f/22 to f/32 it reaches a high level of 0.15% and above.
