I guess I misunderstood your intent. I re-read your posts here and think you are saying that, based on the thread title, it would be good share the existence of another thread where a physical incompatibility problem (newly announced by Sigma) is being discussed.
There is an outside chance that the two are related for at least some users and so it may be a good idea.
