Panny G9 questions: I.S. and exposure weight

I disagree with the above comments. The 100-400 has a ‘Power OIS' on-off switch, which can switch the lens stabilisation off independently from the in-body stabilisation. So it can either use the combination or in-body or completely off. What I’m not sure about is whether the off in-body also switches the lens OIS off. I suspect it does. But as long as that is ‘on’, there is a choice of both combined or in-body alone.

The only compatible lens I own is the tiny 12-32 with Mega OIS with no switch on its body. So the switch in the main menu controls both on my GX80.

As to centre weighted, not sure I’d choose to use it for birds in flight unless they were very low flying with a dark background. It is not ‘spot metering’ and I think it might be advantageous to link the metering point to the focus point if your camera allows this. This can be done on Olympus cameras but can’t say I’ve noticed it on my Panasonics, but mine are not the latest models.

Re: IS on the G9: it is all or nothing, even with a lens that has a 'Power OIS' switch. My PL 50-200 has such a switch, and if I turn it off, all IS functionality turns off as well. It can also be controlled by the in-camera settings, but the physical switch overrides these.

However, for the OP: those in-camera settings do have three options: Off, On, and Panning. That last only compensates for vertical movement, assuming that horizontal movement is deliberate as you try to follow your subject. You might want to experiment with this and see which of the two "On" settings works best for you.
