Isn't the write-up on Tokina at Wikipedia pretty clear about the relationship between the companies?

Tokina - Wikipedia, the free encyclopedia
Wiki is at least partialy wrong: the 16.5-135 has been known to be a Pentax design.

Does anyone know with 100% certainty which lenses are designed by Pentax, which lenses are Tokina designs, and which ones are from a joint effort?

I know there is a of speculation, but which ones are documented and can be proven with supporting evidence?

A search in the frum should provide you with answers.
Patents have been found.

Unless mistaken, 8-16 and 12-24 are Tokinas, rest is Pentax (including that strange 16.5-135 Tokina zoom).

Perhaps Andy means that they belong to the same Keiretsu?

Hoya Corporation belongs to the Sanwa Keiretsu. The bank belonging to that Keiretsu is Bank of Tokyo-Mitsubishi UFJ. That very same bank is one of the banks of Tokina Co.Ltd., so I suppose it belongs to the same Keiretsu as well. And as we all know, Pentax Imaging is a division of Hoya Corporation.

I think that the Keiretsu interface between Pentax and Tokina is an accurate description.

The Tokina entry in Wikipedia emphasizes separate engineering and design groups. I would add that all the corporate literature I have found indicates they are both owned and managed completely independent of each other.

Definitively, they are NOT part of the same corporate ownership or management group.

From the looks of their website and the description on the "About Us" and "Our Parent Company" pages, it looks like THK is just a marketing and distribution JV between Tonika and Hoya; the about us page says that Tonika bought Kenko in 1993.

Please take another look: that reference suggests that the merge (sic) was between Kenko USA (a US-market distribution company) and whatever THK (a US-market distribution company) was called before the merger. Of US-based distribution companies.

That particular language does not indicate that Tokina Co. of Japan bought Kenko Co. of Japan.

This has been hashed to death elsewhere but I wanted to add some clarity to the above post.

The answer would appear to be relatively simple: a Pentax 135 f 1.8 would cost more because it would be autofocus while the Zeiss is manual focus, i.e., no motors or autofocus algorithms to puzzle over, just nice, simple craftsmanship. In addition, the Zeiss lens has an economy of scale advantage, since it is made in all of the popular mounts and therefore has a much larger customer base.
The Sony Zeiss is an AF lens. Zeiss does not make a MF 135mm f/1.8. I'm not sure what lens you are thinking of.

Pentax makes a bunch of odd focal length primes that is sells in small quantities. Not a lot of economy of scale with the 31mm Limited or the 77mm Limited.

Of course, small quantities, if not they could not be limited , these lenses are meant to be produced/released/sold in small quantities, and the odd focal length is part of the 'optimised' designů
Never the less, I do like them.

Right then, lets get this straight...

Hoya owns Pentax, which owns Tokina, which owns Kenko, which owns Tamron, which owns Sony, which owns General Electric, which owns Little Timmy's lemonade stand. Timmy used last Saturday's earnings ($3.10) to buy a controlling interest in Hoya corp.

Now he is his own Grandpa...

A good teleconverter has been a clear gap in a lens lineup including professional grade long primes... Has to be WR ...

Also, a cheap fast prime! Canon, Nikon, even Sony have them! Meanwhile I have to go around ebay begging for a used F 50 1.7 for twice the price?!
