Canon EF 24-85 mm f/3.5-4.5 USM

5. Chromatic aberration

The Canon EF 24-85 mm f/3.5-4.5 USM corrects chromatic aberration quite well for the lens, which is not equipped with any low dispersion glass elements. The only problematic point is the wide angle, where its minimum levels are reached at the most popular ranges: f/4.0 and f/8.0.

In the case of longer focal lengths the chromatic aberration is noticeable only at wide aperture. Even stopping down the lens slightly improves the situation in this category.
