Leica Apo-Summicron-M 75 mm f/2.0 Asph
5. Chromatic aberration
The APO letters in a lens’s name oblige to a proper behaviour and this lens doesn’t disappoint us here- it can be seen on the graph below.

Chromatic aberration shows weak correlation with the aperture value, increasing just slowly from 0.04% at the maximum aperture to 0.07% by f/16. The level ranging from 0.04 to 0.07% is very low so in the pictures this aberration shouldn’t bother us at all.
