Not too lessen your resolve not to buy the lens 🙂 but in practical use I seldom see any of the issues demonstrated in this thread. And I use the lens a lot mostly wide open in a variety of scenarios. As I stated before the correction of this lens is on par with the Loxia 85 which is darn good in itself (not APO but not far off).

I have to admit, the latest images of the branches against the sky is really tempering my desire for this lens.
I already have the Loxia 50 which is a great landscape lens at f/8, where I use it. I already have the CV 65 for true APO performance. If the CV 50 were perfectly APO wide open I'd go ahead and pick it up, as a more compact APO walkaround, but at this point I'll just use the 65 for those use cases and deal with the size / weight.
