P.J. Alling Fri, 19 Feb 2016 14:41:50 -0800 Pentax Fora seems to think that the new lens is made by Tamron, but AFAIK Pentax never had a relationship with them, while a number of Pentax and Tokina lenses were in recent history co developed, including the 10-17mm fisyeye zoom and the 12-24mm.
__________ As someone else noted, Pentax has gotten super zooms and the old FA 2X TC from Tamron. I suspect the current DA 18-135 is a Tamron design, also possibly the DA 16-85 (which is now my go-to lens). As for the Pentax/Tokina lenses, Tokina developed the 12-24. All the other joint Pentax/Tokina lenses were designed by Pentax. As for the rebadged Tamron lenses, I suspect that Pentax put off a decision on the full-framer until the last minute. Then there wasn't time to develop lenses for it in-house. Hence they went to Tamron. And Jun Hirakawa now works for Tamron, and he may have been involved in designing them. These rebadges are reviewed to be quite good.
