His results with the Pentax 70-200 are much worse than mine- Failed to make focus adjustments? Bad copy? I don't know, but it's simply a much better lens than the results he was getting from it show.

I can only question his skills, or his motivation.
My copy is punishingly sharp wide open on both my K-3 and K-1.
have you commented on YouTube - I don't want to launch a Revenge of the Pentaxians type of thing, but he's simply wrong.
