Canon EF 300 mm f/4L IS USM
5. Chromatic aberration
Chromatic aberration won’t disturb us while working with the tested lens. Its level, measured during our test, was within the range from 0.03% to a bit over 0.05% - it means a negligible result.
The situation changes after connecting to a converter. The aberration immediately reaches the medium level and, on stopping down, gets near high.
