5. Chromatic aberration

As you can see in the picture crops below, the longitudinal chromatic aberration is a huge problem of the tested lens. What’s more, it is so serious that the stopping down doesn’t help much. We get an impression that its level by f/2.8 is almost the same as by f/1.4.

The lateral chromatic aberration is quite a different story, as you can notice on the graph below.

On the APS-C/DX sensor’s edge and on full frame’s edge the aberration is always low, never even reaching the medium level. It is a much better performance than that of the Canon 35L, the Nikkor 35G or the Sony 35G which could have the aberration even of 0.15-0.20%.
