Sample movie filmed with the Panasonic Lumix GX80 GX85 in its 4k UHD / 25p mode.

Gordon says in the video above that he is using aperture priority in f/3.5 - hence the shutter speed must be all over the place. In fact, in very short segments (like when he shows the front white grid of an Orange amp), the jitter is diminished.

Like his reviews, but movie is not his speciality. :)

Shot handheld with the new Lumix GX80 (pre-production) and Leica 15mm f/1.7 lens. No post stabilization only the 5-axis active in camera!

It's tempting to compare the GX85 with the slightly more sophisticated GX8, which has been on sale for a while. Resolution-wise there's not much difference between them (16MP vs 20MP), so if you're looking for an enthusiast-orientated, compact, interchangeable-lens camera with 4K support the GX85 is an attractive option. The new sensor (without low-pass filter) delivers sharp pictures with natural-looking colors and excellent movie recordings.

well, it made me a bit frustrated about 5 axis...And the pen-f looks great.

possible additional benefit to stabilization: by reducing jerky motion and jitter in the signal the codec is able to encode less motion/changes in the signal so even if you have to stabilize in post to get it even smoother stable video, you have more usable information in the signal. So on chip stabilization or in lens stabilization is like using noise reduction before encoding, which makes it more efficient or more resolved (all other thing being equal) with the same bandwidth. Probably something like: people will see less macro blocking when switching on stabilization. Now if there is no motion in the scene then it won't help, but for run and gun, I imagine it will factor (especially with extreme motion) - though it may be described as: it just looks better with stabilization on.

Again, GX80 beaten by Olympus (in 1080p).

I've asked Mathieu from Mirrorlessons to make a test of the 5-axis IBIS with an adapted lens - since no one is testing it. He sent the link, made the test with a Voightlander Ultron 28mm f2.
