5. Chromatic aberration

The picture below shows how the chromatic aberration changes, depending on the focal length and aperture values. Its performance is strikingly similar to that of the stabilized Canon 70-200 f/2.8 version. It is curious indeed because both instruments differ significantly when it comes to the number of elements and groups.

Not trying to catch all the nuances we can say here that, as long as we don’t hit on an idea of connecting the converter to the lens, the chromatic aberration in the Canon EF 70-200 mm f/2.8 USM will be totally unobtrusive. Its level is lower than 0.08% everywhere which allows us to call it low for the range extremes and imperceptible at 135 mm.

With the converter attached, the situation becomes different. At the maximum aperture it is still not bad but on stopping down we see the problem increase even to a level which can be called high.
