5. Chromatic and spherical aberration

Chromatic aberration

The 'APO' letters in the name of the lens promise you a lot so in this category our expectations were really high. Still, we weren't disappointed. While looking at photos below you can find out that longitudinal chromatic aberration is corrected very well.

The aberration shows a slight upward trend from about 0.02% at the maximum relative aperture to a bit over 0.04% with the apertue significantly stopped down. Still it would be difficult to complain because almost all that trend fits a range that we usually describe as very low. It means even on stopping down the lens you shouldn't be able to notice any chromatic aberration in real life photos practically at all.

Spherical aberration

First photos of this chapter don’t feature any ‘focus shift’ effect. Circles of light, generated before and behind the focal point, look a bit different, but these differences aren't especially pronounced. You can safely assume that the Voigtlander Apo Lanthar 2/50 doesn't have any serious problems with correcting spherical aberration.
