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.
