AF100 / AF101 / AF105 Master Lens thread

All,
Coming from a GH2 to AF100, I notice that few lenses act differently on the AF100 even though they're both four thirds and micro four thirds. While currently I no longer own a GH2, I think it's reasonable to assume many AF100/101/105 owners carry a GH2 for backup/b cam reasons. With that, I'd like to start a master thread that contains relevant lens information and how it performs on each camera for video purposes.

For example:

Olympus 14-35 four thirds lens:
14-35mm (effective 35mm = 28-70mm).
Aperture - F/2.0

AF100
Autofocus: No
Push Focus: Yes
AutoIris: ?
Notes: Clicking noise while zooming at focal lengths other than wide-open (F/2.0). I.E. F/2.8-F/16.

(Other stuff here; I'm running late and will update later)

We could put these in groups and update them as lenses are released. I really would love one big thread to read about all the possible lenses and the caveats/pros and have them all compiled in one thread.

Like how adapters work with certain lenses; if a lens extends for use in a matte box, etc.

I would love to see all the pooled community information on not just 4/3rds and micro four thirds, but Cosina, Nikon, Canon, Tokina, Zeiss, etc.

For example, I'll bet most of you haven't used a Panasonic Leica Summilux 25mm F/1.4 micro four thirds on the AF100. Do you know it breaths quite a bit on the GH2 during autofocus, but hardly at all on the AF100? It's little things like this that the brochure may not tell us but you experts in the field can.

Hoping for a sticky on this. I like lenses, and I love my AF100.

Some notes so far:

Olympus 14-35mm F/2 - At F/2, there is no Iris "flicker" while zooming. Stepped down at any other aperture, this lens will flicker.
Of note, different results with other cameras. With the GH2, the iris flickers @ F/2 but not at other f stops. With the Panny GF2, it doesn't flicker at all at any setting.

Sigma 18-50mm F/2.8 four thirds mount macro lens:
Iris does not flicker or change on the AF100 no matter the F-Stop. Autofocus does not work, and surprisingly, the "push focus" feature does not either. Auto-Iris does work though. Used with the AF-100 and the Panasonic 4/3rds to micro four thirds adapter. Strangely enough the autofocus works (and actually surprisingly quickly) on a GF2 camera.
