5. Chromatic aberration

One glance at the photos below shows that the lens doesn’t have any problems with the longitudinal chromatic aberration.

Sigma 105 mm f/2.8 EX DG OS HSM Macro - Chromatic aberration

The graph below shows the result of our measurements of lateral chromatic aberration on the edge of the APS-C sensor and full frame. The lens on both of them shows a similar level, amounting to about 0.02%, which, additionally, doesn’t depend on the aperture value. Of course we should mention it is a negligible level, not disturbing at all. Here the Sigma fares a bit better than the Canon which had the aberration level ranging from 0.06-0.08% and a bit better than the Nikkor, which results were near 0.05-0.07%.
