Boy, this is definitely a question that needs to end up in the FAQ!  I
think I've answered it three or four times in the last two weeks or so.

In short:

1) Yes, there is such a beast.
2) Yes, I've used it
3) It works splendidly with lenses up to about f/4 ... over that and
the light falloff is getting to the point the AF system starts
hiccuping, even with the MZ-S.

I use it primarily with an A 50/1.4 and a Tamron 90/2.5 and it works
just fine.  Don't even have to diddle with the host lens' focus point
very much.  I've also used it with the A 200/4.  Does a bit more
hunting, and you can just generally tell it's not as happy as it could
be with the amount of light getting to the AF sensors.  Also have to
fiddle with the focus point more than the 50 or 90.

Just for giggles, I tried it with the SMC 400/5.6 and Tokina 400/5.6
... those were basically nonstarters due to the lack of light ...
wouldn't lock onto the subject except in very bright circumstances.
