Venus Optics LAOWA 9 mm f/5.6 FF RL
5. Chromatic and spherical aberration
Chromatic aberration
In the case of the Laowa 9 mm f/5.6 FF RL it would be difficult to speak about any colouring of out-of-focus areas because, with such parameters of the lens, there are hardly any such areas at all. A photo taken at the maximum relative aperture does show slight colouring of areas before and behind the centre of depth of field. It seems that, despite employing two low dispersion ED glass elements, the tested lens doesn't correct longitudinal chromatic aberration in a perfect way.![]() |

The graph is quite untypical. The CA level increases very quickly as you move further away from the frame centre so on the edge of the APS-C sensor, close to the maximum relative aperture, it reaches high values. Then it starts to decrease and it stops being bothersome on the edge of full frame.
