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.

The correction of lateral chromatic aberration can be described in far warmer tones and the graph, with its performance depending on aperture and the size of detector, shows it very well.

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.
