5. Chromatic and spherical aberration

Chromatic aberration

The tested lens doesn’t have almost any problems with the longitudinal chromatic aberration. Photos below prove that the aberration is corrected well both at 200 and at 400 mm.

Let’s see how the lens correct lateral chromatic aberration – the results, depending on aperture values, we got on the edge of the APS-C/DX sensor and the edge of full frame are presented by graphs below. Sigma C 100-400 mm f/5-6.3 DG OS HSM - Chromatic and spherical aberration

There are no problems either. The highest level of the aberration is reached at 300 mm after a significant stopping down but even at that place it can be assessed as just medium. In case of other combinations of apertures and focal lengths the chromatic aberration remains low or very low.

As you see, the Sigma doesn’t differ from its more expensive, brand name rivals. In fact all three lenses, described here, present a very even, top-level performance.

Spherical aberration

First photos of this chapter don’t show any “focus shift” effect. Circles of light we got in front of and behind the focus aren’t identical but the differences between them are slight, concerning mainly the intensity of rim. It can be said that the tested Sigma doesn’t have any noticeable problems with spherical aberration.
