Welcome on board, Tanja.
Tokina lenses are known for rather high CA figures. However, CAs are relatively easy to remove in post processing.
The improved coating of the version II model is said to help to reduce flare (another issue of this lens), but probably won't do much about CAs. CAs are (or lack of correction of CAs is) mainly a result of the optical design, the glass elements used.
So, unless they also changed the optical design, I wouldn't expect significantly better CA behaviour from the newer lens.
