In my own use, Sony has no problems with IBIS
and OIS/OSS running simultaneously ... but I'm
not noticing it performing better than IBIS alone
[a7XX with A-mount] nor better than OIS/OSS
alone [a6000 with native OSS lens]. No problem
or interference if both run but no distinct benefit
noticed by me, and plz note that I'm frequently
working dim light and slow shutter times.
OTOH, Panasonic's claim that "Dual IS" is better
than either OIS or IBIS alone DOES seem, from
my use, to be really true. Panasonic OIS comes
in two flavors with silly names: "Power OIS" and
"Mega OIS" and they state that only "Power" can
combine with IBIS to create Dual IS. That also is
observable, in my experience.
So, I'm not seeing any "battle" between OIS and
IBIS. My Canon and Nikon SLRs running IS/VR
seem to provide about equal levels of IS as from
the IBIS alone in my Sonys [A-mount lenses on
a7XX and a6500 IBIS bodies].
Admittedly, any of the above that provides just a
1 stop improvement over another would escape
my notice. But by in-use observation, any 2 stop
improvement would be noticed, and on that basis
I feel that Panasonic Dual IS does offer 2 stops,
or very close to 2 stops. No hard data, but I am
doing my "most comfortable" hand held dim light
shooting with Panasonic Dual IS.

My only experience, USER ID - is with my Sony alpha a77 II and a Sigma 105 OS HSM Macro. Sigma recommends turning OFF the OS for use with this camera. If you do not - what happens - is - both OS and IBIS battle for priority … and the results are not so peachy ….
