Curious if it compensates for Olympus zooms too actually. Any 12-40 users on panasonic bodies care to chime in?

I noticed that the G9 and the Olly 40-150 2.8 Pro combo is not parfocal and does not use any compensation to overcome it.

Interesting, thanks. So, one more reason to stick with same brand lenses for zooms.

Now the question remains if Oly bodies do any sort of compensation for zooms of either brand.

Why?

Doesn't the example show the possibility (which is my assumption) that the lens manages it own corrections of focus to maintain parfocality; after all, these lens know their own characteristics and could adjust accordingly (just as they used to do using mechanical designs in the past).

Nothing to do with the camera body for this function; AF is not involved.

Exactly, the lens is doing the correction by itself, nothing to do with the body. For example, the 9-18mm and 12-50mm Oly lenses I own are correcting themselves as expected on my Panasonic bodies.
