It’s a little hard to parse the barely translated text, but All lenses compatible with Dual I.S. 2 are backward compatible with original Dual I.S. bodies: https://av.jpn.support.panasonic.com/support/global/cs/dsc/connect/dual_is.html

Also, the G9 and GH5 also support Dual I.S. 2 – the G80/85 isn’t alone!
