Sigma 70 mm f/2.8 EX DG Macro

5. Chromatic aberration

The chromatic aberration, measured by us, showed some slight declining tendency with the closing of the aperture and ranged from 0.10% to 0.085%. It is a medium value so the correction level of this aberration should be considered satisfactory.

How the Sigma compares to other devices of this class? Unfortunately unfavourably. The aberration in the case of the Tamron 2.8/90 also decreased with the aperture but it was much faster; it became practically imperceptible already by f/5.6. The performance of the Sigma 2.8/105 was simply outstanding because the level of that aberration never exceeded 0.03% for the most commonly used aperture.
