Distortion

Chromatic Aberration

In our shots with the Canon 5D Mark III we noticed some chromatic aberration throughout many of our test shots, often manifesting itself as a one or two pixel soft fringe on the lateral edges of slanted edge targets. We noticed a green fringing coupled with a purple/reddish hue on the opposite side in several of our test shots. This was rarely significant, only really noticeable at 100% magnification, and only appeared at the extreme ends of the zoom range (with the in-camera chromatic aberration correction turned off). The only issue here would be that images may lose some fine details due to misplaced foci. The one disappointing factor is this is an L-series lens, which should theoretically offer better performance for the price.

Distortion

We noticed a fairly typical distortion pattern with the 24-105mm kit lens, with a barrel distortion at wide focal lengths giving way to a slight pincushion distortion ad the mid and telephoto points of the focal range. At the wide end of 24mm, the barrel distortion measured at a slightly noticeable 2.66%, falling to a pincushion distortion of around 1.8% through most of the rest of the zoom range. The 2.66% isn't a great score, but it's easily correctable in software, as the 24-105mm f/4L lens is a profile that's commonly included in such tools.
