Does anyone know if dual IS works with zuiko 12 100 mounted on a G80?

Have anyone tried G80 with metabones speed booster ULTRA 0.71x Canon EF? Sample footage?

Panasonic G80/G85 image stabilization freezes in cold?

Not my example but I shoot much in cold winter conditions with my GH4 and have not seen this issue with lens OIS (My 14-140mm II vibrates always in hot and gold weather). I hope the GH5 IBIS will not have this issue.

It is strange that GH4 has the best sensor and the best iso score but still worst high iso video.

I wonder how Panasonic can change a good RAW sensor to bad video sensor? I think GH4 has more FW processing power than G85. At least 4k AF is much faster in GH4. Maybe G85 LSI has still more power and wisdom.

If the G85 good high iso is done by LSI processing I wonder if it is possible to get similar result with GH4 and post processing.

@Vesku "It is strange that GH4 has the best sensor and the best iso score but still worst high iso video." Do you have a source for this "worst high iso video" comment?

ISO test

Here's a test I did with the Lumix G80/G85 (whatever!) plus Metabones Speedbooster 0.71x and Tamron 24-70mm 2.8 VC Lens. In short - IBIS is working great with it now, but no Dual IS. When used with this camera, the VC (Vibration Control) is disabled to allow the IBIS to function properly. At least that is my understanding of it. The VC works perfectly with my GH4 + SB

Panasonic issued three new firmware updates: G80 (G85) firmware update Reduced operation noise during the shooting standby or the motion picture recording. Dual I.S.2 function with the interchangeable lens H-RS100400 is available.
