Panny G9 questions: I.S. and exposure weight

I have two questions regarding the Panny G9:

1. When I am shooting in animal/bird/human detect mode, if I have exposure set to "center weighted", is the center weighted point the center of the image ... OR ... is the center weighted area the focus point? Prior to animal/bird/human detect mode being available, I typically put the subject in the center, half pressed the shutter button (locking exposure & focus), recompose and then fully press the shutter button to take the shot. Since I started using animal/bird detect for wildlife, I've been using the "multiple" exposure mode. However, I prefer to be in control of what I want exposed properly and not turn that task over to the camera's firmware.

Good question, not Sue of the answer.

2. When I use the G9 with the PL100-400, can I have sensor image stabilization ON, but have the lens stabilization off? When I have the lens mounted on the camera and image stabilization is ON in the camera menu ... AND ... the lens switch is set to stabilization, I see an icon on my LCD display that says "Dual 2". But when I turn it off on the lens, the icon changes to OFF. To me that means both in body and in lens are OFF because I turned it off on the lens only. (One may ask why I want to do this? Good queston. When shooting moving wildlife (e.g., flying birds) I use a fast shutter speed (1/2500 sec) with stabilization OFF because I'm under the impression that IOS interferes with getting sharp focus. However, maybe there's an alternative to everything ON or everything OFF. I'd like to experiment with this, if the two can be set independently with the G9 and the PL100-400.

No, Dual IS means both camera and lens ISS working together. So, if you switch off the lens’s IS then Dual IS cannot operate but the camera’s IBIS continues to operate. Update - not now sure this is correct.

I use Dual IS but still go for shutter speed of 1/2000 or more, if possible. The IS is compensating for your movement not the subjects.

Thanks,
