Re: Panasonic GH5 is coming

Well that certainly makes sense. I won't be banking on anything until it is released with the specs & i can actually go out & buy it. Who knows what they have up their sleeves though??

Have you tried non stabilized lenses on the camera? That's what IBIS is actually made for and the difference is like night and day, you can't even compare because the difference is so ridiculously big. One might question the use of IBIS on a more professional camera but just like Canon's DPAF these functions can be a godsend for documentary type of shooters, such as myself. Anyone who shoots in controlled environments on a tripod will probably never need any of these automatic aids but both have proven their usefulness, also on professional shoots. I even consider IBIS as a part of what makes M4/3 camera's so great, small size and low weight which makes a perfect travel companion and the addition of IBIS just makes it so much easier to use, last step would be to give the camera something like Canons DPAF.

I have to say though, that the ergonomics of the GH4 are far better than the GX85.
Yes but what else would you expect? The gx85 is a pocket camera that comes with the usual limitations, you buy such a camera because it's so small, not because you would expect it to have the same ergonomics as a bigger camera.

One thing i definitely don't like so much about the IBIS on the GX85 is the noise it makes
You also can hear the stabilization on the Olympus EM1 so it might be "normal" but Sony has proven with their BOSS system that this doesn't need to be the case but it's not the actual sensor that moves in their case so that might explain the difference. The noise the stabilization makes however does not bother me at all, what does is the fact this noise gets transferred into the sound making it unusable at times, I do hope that the G80 and the GH5 (if it has IBIS) have found a way to eliminate that on their internal mikes or at least can give a clean recording using it's mike inputs.

Re: Panasonic GH5 is coming

10bit 4:2:2 60p DCI 4k?

My God,.....how are they going to control heat? The G5 HAS to have a fan....a significant sized one! Can anybody see this happening in a passive cooled body?

That's allot of CPU power for that little GH5 battery too.

Wow.....this is one HELL of a shot they are firing at Sony. By announcing it so boldly 6 months early, Panny is saying "Go ahead Sony,...we DARE you to go 10bit on your Alphas!"

I think Panasonic might be VERY confident that Sony will not cannibalize their fleet with a new 10bit Alpha model and Sony will likely back down from the GH5 challenge. For Panasonic to reveal it's cards soooo early, REALLY shows how confident they are. It speaks volumes about their mindset and attack plan.

I love Sony but I just dont think they have the guts to do a 10bit, 4:2:2, 60p consumer camera. There is just no way in Hell that Sony takes a swing at Panasonic's GH5 fast ball pitch. They are just going to look away and accept the strike-outs on this one.

Wow,....Is this is an industry Earthquake?.

The announcement from panasonic said 10 bit 4:2:2 4K at 25 or 30p and that it also could shoot 4k 60p but no mention there about it being 10bit, unless some new info came out?

Very good point Noa. I have only tried it with a long telephoto lens & the results weren't that great. With wide lens' though, i'm sure it would perform very well.

I really only bought the GX85 as a little brother cam to the GH4. In most cases as a static wide shot, but also as a backup to the GH4.

Yes I totally agree with your thoughts on the sound recording. They cannot release the GH4 with sound issues from any IBIS system like the GX85. Let's hope they can make it work somehow!

Then either your gx80 is not working right or you have not set the stabilization option in the menu because that is not my impression at all. I shoot handheld with a 75mm f1.8 (or 150mm full frame equiv) a lot at receptions and my footage is near tripod like, this is impossible to achieve with my gh4, it would jitter so bad that it would be unusable.

Interesting. So it's possibly 4K 10bit, 4:2:2, 30p, with an option of 8bit 4:2:0 60p.

If this is true, this is still every bit as ground breaking. This is nuts.

Panasonic has the luxury of doing this because it has no model above it to protect. Varicam is a Super35 camera that is WAY out of the GH4/5 market. So Panasonic has nothing to worry about.

Sony? Yeah, they have models all over the place at many price points. So for them,10 bit internal 4k is a FAR dangerous marketing problem.

Sony consumer Alpha division might love to give 10bit to a brand new A9 or A7s-III but the Sony PRO department management would likely protest that internally to high heaven. The XDCAM teams/groups/managers REALLY dont want 10bit 4:2:2 Alpahs out there!

Re: Panasonic GH5 is coming

I would only guess that's it's typical Micro 4/3 sensor low light performance. Possibly better noise reduction.

We know for a fact that Sony Semiconductor now manufactures a Mirco 4/3 sensor in their catalog. I heard that Panny is buying it today but that's only a rumor. Is the GH5 a Sony sensor? Who knows? We know they are buying Sony 1 inch-type sensors today.

For me, the bigger mystery is: How will Panny read out the GH5 sensor? Are they pixel binning? Are the line skipping? Are they doing what Sony is doing with reading out all pixels, processing and scaling down?

Re: Panasonic GH5 is coming

Even 4.5K or 5K would have been nice.
