"I believe Pop Photo tested this variant and deemed it better quality than the Pentax branded version, but admitted they are the same design, construction, and probably same plant ."
No, that's not what Pop Photo said. Pop hasn't tested the DA 50-200 yet (or at least they haven't reported a test of it). What the magazine said was that in some ways it performed better than some of the "professional" f2.8 telezooms they have tested. Then they worried about whether its plastic build will hold the lens elements in alignment for the long run. These observations certainly apply to the Pentax version too.
