Pentax lens roadmap 2017
#39
I can say that many of the optical characteristics of Tokina, mainly monstrous chromatic aberrations of the 4 pixel wide variety, which is one of Tokina's traits, is to be found in the Pentax DA*16-50mm F2.8 SDM lens as well as the Tokina version.
Pentax's lenses as a rule control CAs nicely and they use their own lens coatings, therefore I conclude the lens to be a Tokina design, it has none of the signature of a Pentax designer and all the signs of Tokina's.

The DA*50-135mm F2.8 is Pentax's own and is a far better lens.

Pentax would do better with a co-operation with Tamron who's mechanical construction, USD motors, optics, VC and above all their coatings are right up to the minute........
..........only the last Tokina lenses have taken on board any of that......with their clunky push-pull AF ring......but most of all their very poor coatings causing all sorts of flare...........really in terms of full spec lenses.......Tokina are pretty far behind the pack.........I've also heard stories about lack of service...........
