Panasonic GX80 5-Axis Image Stabilization.

The 4K camera scene is slowing down now that it's only Panasonic vs Sony. High frame rate 4K is still no where to be found. Panasonic seems to want to take on Olympus and introducing their own 5-axis Image Stabilization. So far it's not confirm that if the 5-axis exist when shooting 4K video, or if it's just their regular Power O.I.S. Something worth to follow if people are in the market for a camera that benefit photos and video:

Panasonic are continually moving forward and introducing higher end features on their budget/midrange cameras. The biggest advantage Olympus had over Panasonic was the IBIS. Now they have an IBIS as good as Olympus AND that now works with 4K video! Olympus just released the PEN-F that still does not do 4K! By the time they release a 4K capable camera, rumoured to be the EM1 mk2 in September, Panasonic will release the GH5, probably with the 5 axis IBIS, 4K 60p and possibly 6k video and photo modes. Olympus like Canon are losing more and more sales to the innovating companies like Panasonic and Sony. Even Nikon is now on board with 4K filtering down even to thier compacts and mid to high end DSLRs. I have an EM1 and EM10, both great cameras which we use underwater in Nauticam housings. But after I got a Panasonic G7 for topside stuff, it is fast becoming my go to camera above water OVER the EM1. Looking forward to September and the possible EM1 mk2 and GH5 face off. I know who I would put my money on.

Recently an UHD premium specifications has come about and there is a lot of confusion about 4K codecs still on the market place, I wrote about it some time ago

Sony and Panasonic are taking the risk of offering 4K under the requirements of REC709 HDTV whilst 4K will go further beyond very soon

The H264 codec used by both Panasonic and Sony is not great for 4K and actually a 4K stream at 100 mbps does not really capture much more information after all of a good 1080p recording codec.

Resolution is only one of the aspects of what the human eye can see and comes after contrast and colour.

It is expected that HDR provided by premium 4K will bring the most difference to the perceived image quality, far more than colour and resolution

To prove the point I have stressed my Sony RX100 Mark IV for a number of months now on land and recently underwater. I prepared the 4K clip and I showed it to my family on the 55" 4K Tv and they said wow great. However I was only displaying it at 1080p, I then put the display at 4K and nobody could see any difference. This is largely due to the fact that the display size required to see the extra resolution is incredible at 3 meter around 70+ inches.

On my land after much deliberation I am now shooting 1080p as the RX100 with full sensor read out and 50 mbps codec performs well enough and I can't see pretty much no difference at all with 4K even at close distance. This is of course not true for many cameras that do not resolve the full 1080p anyway.

It is likely that it will take a couple of years to define the disputes around 4K and get into real benefits. Furthermore most of the displays do not support HDR anyway

So if you like me have a normal 55/60" TV and watch it at 10 feet 3 meters and the TV does not have HDR you will not be able to see any benefits of any sort.

Only watching on a computer monitor will show the extra pixels

This thread is supposed to be about the GX80 (specifically the IBIS), why are you talking about 4K vs 1080P, TV screen size, viewing distance etc.? Please stick with the topic.

At the mean time, this is the first brief review of the Dual IS on the GX80:

http://www.thevideomode.com/news/panasonic-lumix-gx80-dual-test-2360/

I think a couple years ago I read that it's difficult to apply smooth IS on large sensor, that's why camcorders have smaller sensor size. Recently acceptable IS only applied to 1" sensor. The GX80 proof that the technology now allows good IS on sensor larger than 1", it probably will be years before good IS can be applied to APS-C or full frame sensor.

This GX85/80. (Anyone know the difference?) is a very good point to the future for Panasonic. To stuff all this in a relatively cheap body bodes well for the GH4 replacement. That gonna be 4K/60fps surely now.

Btw. This past FW update with the post focus is very clever.

It's alsogreat to see that perhaps they have stopped the race to 20mp and gone with a 16mp sensor without the low pass filter. Wasn't a fan of the increased crop on the GX8.

I think Andrew at EOSHD said it the best, Olympus have been caught napping. Any advantages they had with their IBIS has gone (* baring using non native glass on the GX85)

So many good cameras these days. How is Nauticam going to keep up!!

Richard, I thought you're getting a AX100 or its next successor?

The way I see it (just my opinion), Panasonic is making progress, but when come to video, it still lack the desire feature of low noise and better color rendition for UW. I'm maxing out my LX100 now that even shooting at ISO400 or 800, the noise is quite bad especially if the water visibility is not good. So in my case it probably make more sense to upgrade once we have a better codec or higher bitrate. But at the mean time, the GX80 should solve the shaky footage issue many of us are having.

With the IBIS on the GX80, it could also be a good B camera to use for topside. Anyone who took boat ride video will surely appreciate the IBIS if it works as well as we expected.

Moses you said it yourself the 4K scene is slowing down outside panasonic and Sony I attempted an explanation. those two companies are taking a risk as many 4K standards are not established. Some others may not want to take the same risk. Canon produced one of the first 4K cameras and has been watching since. In a one year or two many more players will come in and things will get better. For underwater shooting iso 400 is norm and 800 happens quite a lot. Having fine grainy noise in 4K is a real problem. The 16 mp sensor of the lx100 and gx85 is the same of the Gx7 and the same that is in each Olympus body. There is a need of step change here for 4K
