In my understanding, it is not a particular lens, but all wide lenses with aspheric element are prone to purple flare. Aspheric element works like a Fresnel prism that splits light spectrum more aggressively than normal spherical glass. Red light with longer wave length refracts more than blue light.

How to fight this purple flare? As others said: use lens hood.
