5. Chromatic aberration

In this category we still recall the failure of the Canon EF-S 17-85 IS, which is the equivalent of the tested lens for small APS-C detectors. So, we were very curious to see how the Canon 28-135 mm would perform in this category.

Fortunately, in this lens’s case there is no big failure. The worst situation was at the 28 mm focal length, where the aberration is visible on a medium level increasing to a substantial level when stopping down the lens. For the rest of the focal length the aberration level is medium at the 135 mm range and small at the 50-85 mm range.
