Venus Optics LAOWA 12 mm f/2.8 ZERO-D
5. Chromatic and spherical aberration
Chromatic aberration
Wide angle and significant depth of field make it difficult to obtain clear out-of-focus areas with this lens. Still even if you try to do so, for example taking photos from the minimum focusing distance, it is difficult to find any tinted fragments. It seems the tested lens doesn’t have problems with correcting longitudinal chromatic aberration. |
When it comes to the lateral version of that aberration you can assess its performance by glancing at a graph below.
On the edge of full frame you have no reasons to complain, especially if you take into account the angle of view you deal with. The aberration keeps a level of about 0.08% so on the borderline between low and medium. The situation is a bit worse on the edge of the APS-C/DX sensor - near the maximum relative aperture it is between medium and high but on stopping down it decreases to medium values.
