Dreamers, all of us. I do think market-niche and pricing considerations must be driving the Hoya folks crazy on this item.........

Not sure if the Pentax 1.7X works with SDM but one good feature of it is that it converts manual focus lenses to Auto.
That sounds like a fantastic feature. Could anyone help me understand how it can do that?

I got one from frank . A good buy .

The 1.7X TC has the AF screw on the body side so the elements can be moved by the in-body motor . You have to focus the lens manually and then the TC will do fine adjustment on it .
