The misconception is not really surprising because Tokina released some of those lenses earlier than Pentax. So what do you expect? :-)
e.g.
Tokina 50-135mm: October 2006
Pentax 50-135mm: February 2007
Assuming that Pentax did really design this lens, it was very stupid to allow Tokina the first shot.
