Igor, Pentax and Tokina collaborated on a number of lenses in the '90s and '00s, as I recall. Part of the deal was that they would only be available for Pentax with a Pentax badge on them. The similarities in focal lengths, sizes, formulae, and features aren't a coincidence.

Does anybody know what happened with Tokina lenses for Pentax? I very much like my Tokina ATX Pro 28-70/2.6-2.8. This was my first lens for Pentax cameras that I bought with Zx5n. When Hoya bought Pentax, Tokina stopped producing any lenses in Pentax mount, and as far as I understood, started producing some of the Pentax lens designs in other mounts (10-17 fisheye, 12-24, 100/2.8 Macro. Now, that the relation through marriage has broken apart, and Tokina again makes lenses on its own, - will they start producing any lenses in Pentax mount? (like the new 16-28/2.8, 11-16/2.8) Or are they still under some contractual obligation that forbids that? http://www.thkphoto.com/tokina/ Does anybody know?
