The manual is telling about Dual I.S or Dual I.S.2. I understand that the Dual I.S. means that there is a stabilizer both in the lens and in the camera but what is Dual I.S.2?

Just a newer, better version. The difference is in the build of the lens. I think. My older PZ 45-175 has dual IS, my PL 50-200 has dual IS 2, & is definitely better.

This is little difficult for me. Does my "Lumix G X Vario 12-35mm F2.8 ASPH Power OIS" has Dual I.S.2 ? There is a newer model with " II " in the name does this mean the IS2?

Just like to get to the bottom of this. I don't like to end up in the situation that I buy a new camera and find out that my lenses need all upgrading to get the best out of the package. For example that 12-35 lens. Do I loose a lot with that in G9 if that is not IS2?

As per 14-140 f/3.5-5.6 mk-I which is DUAL IS 2 compatible on G85, vs 12-35 f/2.8 mk-I which is DUAL IS only, there should be around <1 stop more effective stabilization on DUAL IS 2 combo vs DUAL IS combo.

I'd like to see this tested. Dependent (obviously) on lens focal length, i'd suspect very small diff... less than 1/2 stop! In fact many testers have found no diff between stand-alone IBIS and Dual IS, both w/ the G9 I believe. My guess is there might be a 1 stop dif at long EFL >200 (FF). Again, the dif 'tween dual-IS one and two should be negligible.

= mostly marketing

Agreed. Despite of the difference there (no matter how small it could be), in real life it would be quite insignificant. The focal length involved, the physically condition of shooter etc might neutralise any advantage.

A reason I picked 12~35 mk-I at a lower cost over mk-II to give up that extra effective stabilisation of DUAL IS 2. 😀
