I've been enamored with shooting 5-axis stabilization.  It's undeniably a great tool and I do rely on it for a lot of work.
Utilizing it for over a year now, and now the motion pictures are tending to look uninspired to me.  I'm finding myself drawn back to the sloppiness of true hand held.  I don't know.  Maybe because strong IBIS has been such a constant in my work, the opposite approach is now more tantalizing than the current?
There's an organic energy in the connection of a (good-not-bad) hand-held shooter to the camera.   A 5-axis camera can dull it.  Add to the fact that I've really leaned on using slow-mo and combined it with 5-axis...for no good reason other than I can do it, if I'm being honest...
Eh, is it true when they say, "the grass is always greener?"
Anyone else that been dabbling in 5-axis questioning it?  Perhaps it's because my work has been "rely"-ing on it...maybe that's the issue.  Why should I rely on a feature that much?  Is it necessary?  Maybe in my older age I'm just yearning for nostalgia and basic simple shooting reminds me of that?
It's interesting because I'm old enough to recall how the hand-held aesthetic upset so many traditional cinema folks as it came into wildly adopted vogue years ago.
Is my 5-axis romance just a "phase?"

I am in charge of firmware at Metabones and I would like to give an official response with regard to GX80/GX85.
We do not expect any EF mount to be able to take advantage of Dual I.S. in the foreseeable future. Either OIS or IBIS should be used, but not both. Andrew reported that "They seem to both operate and ignore each other, leading to problems." We could confirm that it is indeed the case when we downgrade to 1.4 or before. This was fixed in 1.5 a long time ago (Feb 2015). It is easy to tell one way or another: if both OIS and IBIS are active simultaneously, vibration will be overcorrected by twice as much and there will be just as much jitter as no IS, which is indeed what we see with adapter firmware 1.4 or earlier. If you are seeing just occasional slow jitter, it is likely you are observing the result of the vibration exceeding OIS' capabilities of that particular lens.
We have a 50-100/1.8 on order, but before that arrives, the most likely hypothesis drawn from Andrew's and our own observations is that adapter firmware 1.5 and after breaks the 50-100/1.8 and the old firmware 1.4 and before breaks all IS lenses (no AF and double correction). If this hypothesis is correct, you are okay with the current adapter firmware except for the 50-100/1.8 and except for the fact that you will be always using OIS but never IBIS.
A new adapter firmware will be around the corner with which we expect the 50-100/1.8 to be fixed as well. There will be a new option to choose between IBIS and OIS on Panasonic in the next firmware, something that is just natural for Olympus but not yet possible for Panasonic. (On Olympus if you turn off lens IS, IBIS comes on, but on Panasonic the lens IS switch turns off both OIS and IBIS.) The procedure to turn off OIS and turn on IBIS on Panasonic is not going to be pretty, but it will be doable.
I enjoy reading Andrew Reid's very informative review and tests, we greatly appreciate his work and we are always listening to customer reports of any issue which might arise. However, we would like to advise our customers that writing to support@metabones.com is the only way to ensure a problem is looked into in a timely manner. I do read eoshd often, but it is not a reasonable expectation that just because something is reported or discussed on eoshd we must be working on it. We appreciate you informing us of any issue via the official support channel in advance. That would greatly expedite the fix.

Looks like the engineers STILL haven't figured out Auto ISO + Exposure Comp in manual mode video in all these new releases. 
GH5 maybe?
