Originally posted by Winder Looking at the board of Hoya and Tokina it looks like the same family runs both, but Hoya/Pentax is public and Tokina is private. They jointly own THK (Tokina, Hoya, Kenko). Pentax is still a new entity to the group and it might take awhile for Pentax to be fully integrated and deals to be worked out.
THK is American distributor of Tokina, Hoya and Kenko and nothing else.
Exclusive distributors of Tokina camera lenses, Hoya filters, and Kenko lens converters and video camera lenses in the US. http://www.thkphoto.com/
