Sigma 180 mm f/3.5 EX DG HSM Macro APO

5. Chromatic aberration

All in all, the chromatic aberration is not a serious problem for the tested Sigma. In fact, near the maximum relative aperture its level is very low. The situation changes when we start using apertures near f/8 or higher, where this aberration can reach and even exceed 0.1% - it means it can become visible in some contrast scenes.

Here again the 180 mm model fares worse than the 150 mm lens which, in this category, had practically constant aberration at an imperceptible level below 0.04%.
