Chris - it can be done. You can put 2/3" B4 lenses on the
$3600 AF100, and with a power supply, you can use the servo zoom. Take a look at this video from Abel Cine:

I love the guys at Abel - but their approach was pretty expensive (
$750 Hot Rod PL adapter plus a
$5500 2/3 to PL adapter).
There's a better way. I would use a relatively inexpensive
$300 B4 to m4/3 adapter, a
$55 power supply and a
$60 cable to power the zoom. If you already have Anton Bauer batts, you can skip the power supply and get
this cable instead.
Darren, over at
AF100 User Central, chose the less expensive option:

And here is a field report with ungraded SOOC sample video:

You won't have camera-controlled autofocus with this approach. If you absolutely need autofocus, Panasonic does make a couple of autofocusing power zooms for the AF (a
14-42 and a
45-175), but they have consumer-style controls and are relatively slow at f3.5 and f4.0, respectively.
Hope this is helpful,
