5. Chromatic and spherical aberration

Chromatic aberration

The tested lens doesn’t have any problems with the longitudinal chromatic aberration and thumbnails below prove that much. At the maximum relative aperture you can notice very slight colouring of out-of-focus areas but it is an effect very difficult to perceive in real life photos.

Now let’s check the lateral chromatic aberration performance with the help of a graph, presented below.

The situation is splendid as well. Results of 0.02-0.04% mean the aberration level is negligible and shouldn’t bother you in real life photos. What’s more, the Samyang once again fares better than the Sonnar although the differences between those two are merely cosmetic.

Spherical aberration

The tested lens doesn’t have either „focus shift” effect or characteristic mist at the maximum relative aperture which is most often connected to a bad correction of spherical aberration. These facts make us think that the Samyang 2.8/35 FE doesn’t have any noticeable problems in this area, especially that the out-of-focus light circles in front of and behind the focal point remain pretty much similar.
