Samyang AF 35 mm f/1.4 P FE
5. Chromatic and spherical aberration
Chromatic aberration
Photos below show quite clearly that the Samyang AF 35 mm f/1.4 P FE doesn't have any problems with longitudinal chromatic aberration. Colouring of out-of-focus areas positioned far away in the frame can be spotted only very close to the maximum relative aperture. The tested lens should be praised here. |

Here the performance of the Samyang can be only praised – aberration levels are their highest at the maximum relative aperture but even there they can be placed on the borderline of low and very low level. On stopping down the aperture it drops to completely imperceptible values.
It's worth adding that this performance is very similar to the performance of the predecessor of this lens - practically in the whole aperture range its aberration level amounted to about 0.03%. The Sony was even slightly better as its level approached 0.02%.

Spherical aberration
On first photos of this chapter it would be difficult to perceive any focus shift effect. Some problems connected with spherical aberration remain visible in the appearance of out-of-focus circles of light we get before and after the focus. The first of the circles features a brighter rim, the second one – softer edges. These two traits are a classic symptom of spherical aberration that is not corrected in a perfect way.
