Changing the optics to accommodate Pentax' SDM ring motor doesn't make any sense, as that is a standard "ultrasonic" ring-type motor. Those are made by various companies, it's not a Pentax exclusive.
Even more, since the Tamron already uses such a motor changing it to a "Pentax" part.... why on Earth would they do that?
