Does IBIS Further Improve OSS Lens Performance?

Can owners of A7II/A7rII and Sony OSS lenses please comment on whether IBIS further improves OSS lens stabilization when the two are used simultaneously?

Or, conversely, if IBIS and OSS are technologies that are not meant to be used together at the same time.

Thanks.
 
They actually complement each other: an FE lens with OSS gives you the full 5-axis stabilization, non-OSS lenses give you 3 axis stabilization.
 
The OSS takes on pitch/yaw instead of the sensor.

If OSS is not present than the sensor takes on pitch/yaw which causes distortion in the A7II. But I just got the A7RII and I don't see any distortion with my Batis 25 lens which has no OSS.

So it looks like they improved the IBIS on the A7RII.

From what I read, there is always 5-axis happening, the difference is which element takes on pitch/yaw. It can be OSS or the Sensor but not both at the same time.

EDIT: Here is a quote from the A7II, A7RII and A7SII product descriptions: "All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization."

Thank you both for those responses.

So it seems that 5-axis is enabled for every scenario -- but if an OSS lens is attached, the pitch/yaw is handled by the lens.

Question (the answer of which may be obvious): For those of us who have only experienced OSS on an A7s, is the simultaneous use of IBIS and OSS significantly more effective at stabilization?

People say that IBIS + Native OSS gives it a tripod feel, it appears that smooth.

However Sony says if you have IBIS + non-Native OSS there may be over compensation happening which may not look good. I've not tested either myself.
 
UPDATE: I used the Batis 25 + A7RII + IBIS more extensively today and I did see some sensor shake when my hands were too still. So the IBIS over compensated a bit sometimes. It was subtle and could only be seen in the corners and could easily be mistaken as shake from hand holding it. So it is very usable but not bulletproof.

EDIT: To clarify the Batis 25 does not have OSS built-in.

Thanks for that input and those tests.

Anyone else using a Sony OSS lens in conjunction with a Mark II IBIS camera and who has comments regarding how much better (or not) the image stabilization is compared to using only the lens OSS?

Thanks.

Erk :Drogar-Shock(DBG): what kind of distortion?

Presently considering to upgrade my A7 to A7II to improve stabilization when shooting in low light with legacy non-OSS lenses but this could be a deal breaker, so a pointer to more info. about this would be most welcome. Does this only effect video or also shooting stills?

It is in this video review on Youtube at 17:33
https://www.youtube.com/watch?v=aTZ0EiUeW-k

He uses the Rokinon 14mm lens which has no built-in OSS and you can see the results in the corners of the frame.

For a related example, this other review by Mathieu Gasquet talks about the IBIS in the Olympus system and he goes into detail about the pros and cons. This video gives you an idea of how the sensor shifts are "hacking" the camera movement in order to give you the perception of steadiness. But in doing so, creates some unwanted side effects:
