In some ligth situation I notice the purple fridging artifact.
How I can reduce this?
Knee?
Sharpness?
external filter?
Thank's a lot.

Avoid extensive contrasts with sharp edges in objects. Control the light, if possible. All cameras suffer from color fringing, all lenses suffer from CA.

Knee Low may reduce the problem a little bit.

Some time ago Elton posted an example of that. The scene was shot with $100k camera and $50k lens and the problem was there... Good lesson for all of us.

It is also possible to reduce this effect in post. Consider 55mm plugin for example. It offers Defringe function.
