Verdict

The Canon EF 17-40mm f/4 USM L showed a very good to excellent performance in the lab as well as during the field tests. The lens exhibited very little vignetting and excellent resolution figures. On the downsode the level of distortions could haven been a little better at the wide-angle setting. Typical for most wide-angle zooms chromatic aberrations can be visible but the problem remains comparatively low. The quality of the construction is next to perfect.
