5. Chromatic and spherical aberration

Chromatic aberration

The longitudinal chromatic aberration is a serious problem for fast, wide-angle lenses - the owners of e.g. the Nikkor AF-S 35 mm f/1.4G can be made painfully aware of it. On the other hand the Sigma 1.4/35 model proved that aberration can be corrected with a success. Unfortunately the Fujinon’s performance is closer to that of the Nikkor than to the Sigma’s. The longitudinal chromatic aberration is clearly visible and even the stopping down to f/2.0 doesn’t help with lowering its level.

Better things we can say about the lateral chromatic aberration – it is slight, no matter what aperture you use, keeping near 0.07%.

Spherical aberration

The spherical aberration is corrected properly – you can’t see its influence either as a ‘focus shift’ phenomenon or in defocused images of light points which are similar in front of and behind the focal plane.
