Samyang AF 35 mm f/1.4 FE
5. Chromatic and spherical aberration
Chromatic aberration
Longitudinal chromatic aberration is noticeable both at the maximum relative aperture and on stopping down to f/2.0. Still the stopping down is able to limit it distinctly. Overall its level is not particularly high; anyway we’ve tested lenses with similar parameters which performed much weaker (e.g. the expensive Nikkor AF-S 35 mm f/1.4G). To sum up the Samyang deserves to be assessed moderately well here. |

In this case most of results are within a more or less constant level of 0.03%. It means the aberration is very low and it won’t bother us in real life photos. A round of applause!

Spherical aberration
The tested lens doesn’t feature any “focus shift” effect or characteristic mist at the maximum relative aperture which is most often connected to a bad correction of spherical aberration. It seems the Samyang 1.4/35 FE doesn’t have any problems in this category, especially that the appearance of defocused circles of light in front of and behind the focal point remains similar.
