May be Panasonic will make price lower due to A6500?

Why is the battery grip so expensive? It's have the price of the body. $199 would be more reasonable. UK gets one for free.

Does anyone know if the contacts on the bottom of the G80 means it can work with the YAGH Module?

This is a workaround for the Sony a6300 to have a headphone jack, since the G85 can have dual recording with the HDMI, this could be a workaround to the missing headphone jack.

Final solution (with least points of failure)

Micro HDMI to 3.5mm line adapter ($5.75)

Mini 5V 3.5mm 2 in 1 Wireless Bluetooth Audio Transmitter, $14.5

Attach using small transmitter cable and use sticky tape to fix them together.

Wireless Bluetooth headphones, per your liking, from $5 to $30

@cas1 the IBIS will stabilize any lens.

It would be nice if the stabilisation is automatically adjusted according to the focal length the camera detects from the lens' electronics. - I think it would be easy to program in firmware / software.

Has Panasonic a to-do list for updating their DUAL IS? - so cheaper lenses like the 100-300 also benefit from dual IS?

I just know that this beast use the same battery type as GH2. Really an appealing upgrade for GH2 owner without the need of CINE 4K video mode!

@DanPV

It also has mike input. But most probably HDMI does not work during recording, otherwise must work.

True, i read it after post it.

Tests lately really improved

Le mode vidéo du Panasonic Lumix G80 est identique à celui du GX80. Nous vous invitons donc à relire la partie consacrée au mode vidéo. Le G80 dispose des intentions de rendu Cinelike D (meilleure dynamique) et Cinelike V (tonalité cinéma). Toutefois, l'option V-Log (GH4) n'est pas disponible.
