From a true professional rigging standpoint IBIS is a pain in the ass.

For guerrilla and low budget productions (which is now almost 80% of production content on web) is perfect.

Gives the bad operator a good camera movement and for the client the ´´feel´´, ending with a better product overall.

In real speaking, from truth, IBIS is grate tech, gives smoothness on shots where if not there, would be very difficult if not impossible to shot it understandingly. But that is where proper use of image with varied technics, real resources from a cinematographic stand point, is that IBIS is just one more tech, is not a language. So its not IMPORTANT for the video oriented GH5S.

In fact any DP would be happy to trade, robustness and low noise, for IBIS.

(...so the floating sensor on the grip car cam....hmmm...ok...all days of shooting and no damage on shortime.... there are 14 episodes dude... dont you have those GH5S? on the truck)

You can always just turn off IBIS when you don't need it. I can understand it if they can't implement IBIS because of technical or physical limitations (i.e. heat, size), but to say that they didn't include it because it's not required for "professionals" is a a bit silly.

Never listen that managers tell you as reason. Because usually they have no idea.

I am 99% sure that they had been forced to do this due to better cooling, to keep some minimal advantage of GH5s.

@Sph1nxster

My advice, wait one more year for the GH6.

It is strong inside rumor that Panasonic really want to copy Sony and fragment GH line as much as possible.

So, it can be as I wrote, that it won't be new GH6 for 2 year at least and it'll be instead new member of GH line. May be something like G9 in GH5 case and cheaper EVF.

Yup, that's exactly what I'm also seeing. The raw noise performance is identical until ISO 6400. I have a strong feeling the video looks improved cause Panasonic has introduced a very good spatial temporal noise reduction in the GH5s which cleans the image much better compared to the GH5 NR algorithm.

At low ISOs, shot noise dominates. Shot noise is usually similar across cameras, being a function of the noise inherent to the light combined with transmission losses through the filters, fill factor, and quantum efficiency. As the ISO is raised, read noise becomes a large factor. Read noise depends on the particular design of the sensor.

@kin869 Right. You turn it off if you don't want it. And, believe me, when you have a camera at a distance, like a balcony at an event, you definitely need it. Then you turn it on.
It is a very useful feature.

Native iso's when using vlog-l and hlg,are listed as 800 and 5000 at Panasonic's website..

Also,ex-tele x2.1 for FHD.

They keep saying 14stops of DR when vlog-l is capable of 12stops..

No IBIS

@Vesku it isn't 14 stops.

Oh that is completely hilarious that there was a blackout while discussing the GH5S! Ha

I'll be buying a camera soon, and between the GH5 and GH5s, it seems that my decision's got one big question. Is the low-light performance of the GH5s worth the extra $400? (Side note: $400 because a GH5 with Vlog is $2100.)

Lots of people have posted good-looking low-light footage from the GH5s, but it's nearly all outdoor nighttime shots. And they look great. And in the higher ISOs, it's really impressive. But my concern is when I shoot indoors, with existing light. As we know, the lights we have in our houses aren't really there for shooting video. And when I shoot indoors with existing lights, it's usually kind of muddy and dim. (Sunlight helps, but can't count on that.)

Are there any GH5s tests out there that shoot in a normal room, with no special light, and no excessive sunlight? That'd really help me make up my mind.

@DrDave Thanks for the reply. You're not the only one to point out that using Neat Video on GH5 footage brings it closer to the GH5s's performance. (It might get even better if I use the 6K anamorphic setting.) And Kai M on YouTube stresses that he's invested in fast Leica glass, so he's been getting good stuff with the GH5 as it is.

So I'm 95% decided on the old GH5. Here's hoping it gets a price drop in the next month.

As @Ironfilm says, the G85 (sort of like the GX85 but in the standard body, and with more dials & features) is almost the same IQ--if I was spending 2 large I would have a tough time choosing between the GH5 body and a G85 with with a Panny 12mm or something along those lines. The bare 5 has some nice pro features though.
Since I buy a set of cameras, I often look for the cameras like the G85 which is 98 percent of the IQ for half the price. Makes you feel better when you drop it, too. And, hey, the GX85 can be found used for ~$450 and you can hack it for CineD and maybe Vlog--not sure about the Vlog but I did do the CineD. Buttons are fiddly but the IQ is very good. I saw a tiny bit of difference bewteen the GX85 and the G85, but the difference between the G85 and the GH5 is super small. GH5 has all-i and other nifty features.....might be worth the extra cash for that tiny difference, I do recommend just renting one before you buy it. Charge the client or just eat it--knowledge has value.
