Isn't this the lens that is speculated to by the same as the Zuiko (i.e.
Olympus outsourced the 35-105).

I don't think so . . .
The "Close Focus" rings turn in the *opposite* directions. On the Zuiko,
this is the equivalent of about a 5mm extension tube; don't know what it
does on the Tokina. There would be *no* reason for a lens maker to expend
the money tooling up to make two precision helicals that work in opposite
directions for complex lens barrels like this, one for their own name and
the other for an OEM, that work in opposite directions.
My *guess*? A little reverse engineering of the mechanicals by Tokina plus
sufficient modification to keep out of trouble [patent(s) ??] with Olympus
along with other changes to make it less expensive. This is done much more
often than many people think.
