5. Chromatic and spherical aberration

Chromatic aberration

Photos below show very clearly that the Fujinon XF 1.2/56 WR doesn't have any problems with longitudinal chromatic aberration. Even at the maximum relative aperture it would be difficult to see any more distinct colouring in out-of-focus areas positioned further away. In this category the new model fares notably better than its predecessor.

Also lateral chromatic aberration is corrected by the Fujion very well – it's enough you glance at a graph, posted below.

This aberration doesn't depend almost at all on aperture value so at the maximum relative aperture it is just slightly higher than after a significant stopping down. In the whole range you deal with levels of about 0.02% which we consider to be very low. It meas lateral chromatic aberration is corrected exceedingly well and won't be bothersome at all in real life photos.

Spherical aberration

In first photos of this chapter it would be difficult to notice any focus shift effect despite the fact that shallow depth of field makes it easier to inspect images in this respect.

What's more, defocused circles of light we got before and after the focus not only are pleasing to the eye but also don't show any significant differences between each other.

Both these effects plus the fact that the lens is able to produce good quality images already by f/1.2 make us think that the Fujinon doesn't have any serious problems related to spherical aberration.
