Sigma 105 mm f/2.8 EX DG Macro
5. Chromatic aberration
If the image quality at the frame edge is good it usually means that the lateral chromatic aberration is well corrected. Here this rule is also true. Looking at the graph below you can describe the Sigma’s 2.8/105 results as nothing more than negligible.

How does it look in practice is shown on a crop below, which was taken from the area 70% away from the field centre.
