Sigma 100-300 mm f/4 DG EX APO IF HSM
5. Chromatic aberration
At 100 mm focal length, there simply is no chromatic aberration for the Sigma at all. No matter which diaphragm was used, its value reaches only 0.05%.
The situations get a little bit weaker when we increase focal length. The value of chromatic aberration in this case reaches 0.12%, which is an average to large level. Taking into consideration the APO, the results could be better, although there are no major reasons to complain about them.
