Indeed. That complaint is a pet peeve of mine...
Tamron 2,8 70-200 and 2,8 24-70 are using the same WR/AW quality range like Pentax * lenses.
Maybe it is a gift from Mr Jun Hirakawa,ex Pentax optic specialist and fired under Hoya!!!
Now he is a Tamron member ;-)
Pentax 16-50 and 50-135 are 100% made by Pentax in the Vietnam Factory,Tokina production is an own thing.
The patents are made under Pentax,before Hoya.
Some of the wideangles are Tokina Patents and are produced in the own Factorys.
The Pentax 12-24 is a Tokina Patent,but built in own Factorys.
The development is a 50/50 thng between Pentax and Hoya.
This relationship is not more exist.
Best regards
