Regarding the issue of "center weighted" exposure, there seems to be different opinions on this matter from those responding to this thread. Thanks to all who responded to this question. I will try to do some testing along the lines suggested by your responses. You answers gave me some ideas for testing. Hopefully, I'll get a clearer picture of what happens when using human/animal detect with Center Weighted vs. Multiple exposure settings. If I get some clear results, I'll post them on this thread.

The G9 manual only mentions this in a footnote under the heading for the FW version 2 update which introduced animal detection: "Exposure will be adjusted to the face when metering mode is set to multiple."

I think the symbol in the manual shows Center Weighted, not Multiple.

The consensus on the issue of I.S. is that when one turns off the OIS switch on a Panny lens (mounted on a Panny body), it turns all I.S. off, including the IBIS. Thanks to all who responded and especially to alcelc (Albert) for the detailed analysis on this issue.

The G9 manual says they can be activated independently:

Nope, it’s multiple.  Center weighted ALWAYS (as far as I know, and would be consistent with Canon, where we could get more info) based on a strict weighting across the image.

Mutiple starts with Center weighted, but modifies (ECs) the exposure using many algorithms which analyses the different parts of the image.  In this case, the human/animal detect seems to be added to the mix.
