5. Chromatic and spherical aberration

Chromatic aberration

The longitudinal chromatic aberration is not a big problem for the tested lens. The photos below show just a slight colouring of defocused images which means that aberration is corrected properly.

The graphs presenting the lateral chromatic aberration values, depending on the aperture and the focal length you employ are shown below. The first one concerns the performance on the edge of the APS-C sensor and the second one – full frame.

The most pronounced problems can be seen at the shortest focal length where the aberration can reach medium levels. When it comes to the rest of focal lengths it won’t be bothersome at all. In this category the results of the new model are very similar to those of its predecessor and the Sigma S 150-600 mm. In their case the chromatic aberration also reached near 0.1% at most and for the majority of apertures and focal lengths remained low.

Spherical aberration

The tested lens didn’t have any “focus shift” effect. We didn’t have any serious reservations concerning the appearance of its circles of light. The only thing that might make you worried is the increase of the intensity of the rim when you pass from in front of the focus to behind the focus position.
