Canon EF 70-300 mm f/4-5.6 L IS USM
5. Chromatic aberration
When it comes to the lateral chromatic aberration, in the case of 70-300 mm class lenses it is not easy to correct as many devices like, say, the Nikkor 70–300 mm VR found out in a painful way. Fortunately optics specialists from Canon drew the right conclusions from the slip-ups of their rivals and, in this category, managed to deal with the problem splendidly. Graphs below show the measurement results of lateral chromatic aberration respectively on the edge of the APS-C sensor and full frame.

According to what we wrote in the article „How we test lenses” the aberration ranging from 0.04 to 0.08% is considered by us as low. Most of the results, presented by the tested lens fits that range so it would be hard not to praise it here.
