Around maximum aperture, chromatic aberration is hard to overlook. The measured value of almost 0.16% is what we call a high level. No wonder it is rather clearly visible in photos. Fortunately, stopping down on the aperture lets us reduce the aberration to an average level.
In this category Sigma 2.8/10 works better with aberration at the level of 0.11-0.12% for all
apertures.
