The Tokina's do NOT have the same coatings as the Pentax versions. Or at least the 16-50 doesn't. There's no other way to explain the difference in flare handling between the DA* and AT-X Pro versions, also the Tokina's have a different colour signature consistent with their other lenses, which is indicative of coating differences. I suspect Pentax does do the coatings, but uses Tokina's specified coatings on the glass destined for Tokina.
-Adam ----- Adam, I would have to check further on this, but my information (from a Pentax unit) is that the coatings are the same. One difference is that Tokina's lens bodies have been poor at using internal design to reduce light bouncing around, even before the joint lenses. Also, Tokina has in the past been pretty poor in the coating area. Now they advertise their new, advanced finger- and waterproof coating on the front element. Guess whose coating that really is? But your point about the color signature would make one wonder. As I said, the information comes from a national Pentax distributor, but they have gotten things wrong in the past.
