To use my lenses on an e-mount body is there a less-expensive yet
full-featured adapter alternative to the Monster?

I've never seen one so expensive before, but then again I've never seen
an adapter that also adapts screw drive AF either.
I kind of doubt that you'll find anything cheaper that actually will
auto focus a K mount lens on a mirrorless body. You'll be buying about
a third of the working bits of a K-70.

How on earth is screw drive AF possible?

I assume there's a motor in the adapter (drawing power from the camera).
The first two pictures (the lens-facing side) show a screw-drive shaft,
and also the two contacts that could provide power and digital signals
for newer AF lenses, and may even provide power for power zoom lenses!
I'd guess there would also need to be a microprocessor to translate
between the various signalling protocols, but that's not going to add
a whole lot to the cost.

Thanks John. Now I understand why PJ says you're buying a third of a K-70!

You know, sometimes I know what I'm talking about. (Too bad the quotes

I was curious, and with Google's help actually found out a bit more.
There are apparently two motors in the adapter (I have no idea why).
And although the contacts, etc., seem to be there, the manufacturer
says that this adapter doesn't support using SDM lenses.

K-70 is only about a hundred dollars more than the adapter $546.95 vs $439.00
for the adapter.

I assume that the adapter is made of the more expensive mechanical
parts, and at a much lower volume so there would be a much lower return
due to the economics of scale. That is unless you have good numbers on
the quantity of Sony users who see serious quality in Pentax Auto Focus
lenses.
