AFAIK, the DA12-24 and DFA100 is a Tokina design.
The 10-17,16-50, 50-135, DFA50 are Pentax designs.
DA35 I dunno.

Interesting. Any source you can link?

I would have thought the DFA100 was a development of the FA100 macro. Do you mean that even that one is originally a Tokina design? Or that Tokina made the "digitalisation" of the FA100?
