GH5S on Ronin SC is shakier than my Mark3 handheld. this sucks I want to sell this camera
@PhotoJoseph microjitters . the camera picks up every tiny slight movement
@PhotoJoseph Ronin app reports balance as Excellent. I mean I do have to learn to move better with it
This is the only one of the other uses where, in turn the ibis is extremely useful! So I vote for GH5! Thank you so much the video!
Only the GH5S sensor is not fixed in place. No stabilization doesn’t equate to fixed in place. I have the GH5S and if I hold it up to my ear and tilt the camera forward and back on the tilt axis, the sensor can be heard rattling, the same as the two GH5 cameras that I returned for this reason. I can also see the sensor rocking back and forth. I find it hard to believe that I’m so unlucky to have gotten 3 defective cameras with loose sensors. I must admit that I was very disappointed to find the issue with the GH5S after having anticipated having a better version of my old GH4.

Watching your video here, the GH5S footage is horrible. Hold it up to your ear and tilt it back and forth and listen to the sensor rattle and report back.

Here’s some footage from my GH5S + Ronin-S + 8-18 mm Panasonic at 8mm. Total junk. And I’ve gone round and round with DJI who has the worst support on the planet. The Gimbal is setup properly.

1) I think you’re correct on it being the shutter or something in that neighborhood, as I looked at it more last night and put my finger against the plastic plates above and below, out in front of the sensor and that temporarily stopped the Yahtzee effect.

2) I understand the mechanics of the thing, how the IBIS works, however I record walks. I walk extremely carefully, heel to two, gimbal at a 45 degree angle out in front, and with the two GH5 cameras I owned, the internal shutter or sensor click, or whatever it is that rattles was audible to the internal and eternal mics and in the resulting footage.

3) I don’t care if others are happy, it’s not suiting my needs. I consider a loud clinking that’s picked up by the mics a problem. For 2000.00 or 50,000.00 I do expect better.

4) See above. Walking steady. I suspect the gimbal is misconfigured or broken. I’ve tried about every setting and configuration possible though. The GH5S gives much better results than the GH5 did, more evidence that it’s the shutter, not the sensor that’s rattling in both cameras.

5) You’re not the first to mention the bitrate issue on that videos. It’s a 4K video uploaded from final cut through the share to YouTube option. It was about 50GB prores compressed to about 6GB for upload. I think you’re seeing the low res/quality version from YouTube. Please check and tell me if it’s set to low quality and if it looks better if you increase to 1080p or higher? What about my other videos? Do they look the same?

Regarding the mic, I use a Rode Stereo Videomic X attached to the camera hot shoe. It was picking up the rattling sound from the GH5 not the GH5S. I returned one to Best Buy and had the opportunity to talk with the camera salesman and he couldn’t believe how loud it was. He was shocked and immediately refunded me.

Regarding the bitrate, I see it crystal clear in 4K on my end, so it’s odd and concerning that you and others see something different. I wonder if my other videos look the same to you?
@PhotoJoseph in my last response I was talking about the GH5S and the GH5. I've owned both. I was making a comparison. I've determined that the rattle is not the sensor (GH5S or GH5), it's a plastic part (which doesn't seem to be the shutter) that sits in front of the sensor. Mystery solved, but it's still audible to the Rode Stereo Videomic X. You probably don't hear it because you don't do walking videos, just a guess.

Regarding compression, I use FCPX. I bought the compressor and now use 50mbps on the custom setting. FCPX doesn't allow such a configuration OOTB.
What they actually should have done is design a way of parking the sensor. I’m sure a couple miniature servos could physically lock it in place? Great test tho. I guess if you want the best of both worlds you just need get a GH5 and GH5S 😂
@PhotoJoseph Not that I know of, but I know <6mm servos definitely exist... On a similar note, do you think using a lens with OSS switched off would still have an effect on the image? I've noticed when filming concerts the bass vibrations interfere with IBIS systems (Sony in particular) but now I've started to think about OSS lens optics floating around when OSS is switched off...
Thx for comparing... I think GH5s pretty stable though... Is your lens has Image Stabilizer in it?
@PhotoJoseph thx for answering! It looks pretty legit though without any IS... great review!
I had to get an in-car shot yesterday and rigged my GH5 + Lumix 12-35 lens with stabilization for BOTH turned ON. I had the camera mounted with two suction cups on the windshield connected to the cage via friction arms. The thing was rock solid. Got the footage off of the camera and it has those tiny micro vibrations. I didn't even consider using my GH5S. I think that I'm going to have to do some tests now b/c I need to re-shoot the footage.
Holy freaking crap. You did a great job of showing the truth behind the lack of IBIS, but you've unintentionally done something far greater: you've shown how much more detail the GH5S captures over the GH5! If you look at the ribs and ends of the metal awning as you drive by, there's SO MUCH more detail in the edges and the reduced rolling shutter becomes obvious too. Thank you for this. Quality content, my friend.
@PhotoJoseph Possibly, but even if that's true, the captured colors are richer as well. The movement shouldn't make the colors look better. I'd guess the fat pixels are responsible. Well, that or you didn't match color styles. By the way, was this with the newer firmwares (2.4/1.2)??
This is a late question. Which lens did you use for this comparison?
Thank you so much!! I wanted to know whether the lens you have used had O.I.S. or not.
Sorry. It's my fault. I couldn't catch all of your words because I'm not an English speaker.
Drives car three times around block to test camera end up in prison cause police though he was pedofile watching kids :D
:D
I was making a joke, but that actually can happen...
This is the reason I purchased the GH5s
I own both. Love both!
I'm shooting a doco at the moment, and the GH5 and the in body stabilisation is incredible when you hand hold it. But the GH5s picture quality is better. Not sure if it's because of the slightly larger sensor? Ps Love you work!
Very interesting! Great post!
You can't argue with ibis lovers. Personally ibis is useless to me unless I do photography. I have my Sony for that. I'm inches away getting rid of the 5 and only using the 5s. 5s and Ronin are light year better than the atrocious warping effect of the gh5, let alone the obvious jitter as was shown here in an exemplary fashion. 👏👏👏👏
Wow! GH5s is rock solid compared to the other two! Thanks for doing this.
I wonder if they could design some kind of trigger in the GH6 that mechanically locks on the sensor when IBIS is turned off. Just so those car and Gimball/steadicam people can be happy.
Yes I'm thinking retractable claws or something like that that mechanically holds the sensor stable when IBIS is disabled.
@PhotoJoseph Never say never ;)
I thought the other issue is that they are actually going using the "entire" sensor size to maximize anamorphic resolution, vs. GH5 which can only utilize a portion of sensor to allow movement. (same principle as with IS lenses).
Freak'in awesome... best actual "example" showing the reason the IBIS was left out. If anyone argues otherwise after seeing this they are just arguing for argument sake! Keep up the good work!
Gr8! What lens was used? Can we see a stabilized native lens footage on the GH5s as well a Dual IS on the GH5 or was the footage shoot on that setup? If you would use the IS Lock on the car body, how would it looked?
Hey photojoseph, were you able to compare the jitter of an ois lens vs non-ois lens?

Also did the lenses you used in this video have ois? Thank you!
I agree!! that's true!! nice job and good conclusion
Lok send me here. 👋
Welcome!!
You've got it completely backwards. Don't watch the roof of the car, watch the background, check the trees. For most people, the subject is not the tripod your camera is mounted on, the subject is the scene you shoot. And b.t.w., the optical stabilization also has a floating element, and even in the non-stabilized lenses there can be a floating focusing elements.
PhotoJoseph I have both. They are absolutely fantastic camcorders! The facts behind the lack of IBIS are plain as day... They couldn't have included it whether they wanted to or not. We could even call it a beneficial compromise. But 'removing' IBIS wasn't a decision that was made to benefit anyone...

... They simply didn't have a choice in the matter.
PhotoJoseph the new dual native system and multi aspect coverage didn't allow for the clearance for IBIS. The primary purpose for creating the S model was to offer a comparative option to the A7 S series cams and their low-light performance. It's just disingenuous to say they 'removed' IBIS... It was in the way and would have required major design changes. Instead it's just easier for them to say they removed it for "real Hollywood professional filmmakers" because that's what sels to indie film wannabes, YouTubers, and gear junkies. 99% of real film pros aren't wasting their time with prosumer grade MFT cams.
PhotoJoseph lol dude, what part of "I have both. They are absolutely fantastic camcorders!" Wasn't clear. The GH5s is an excellent camera. I'm just clarifying the misinformation that they voluntarily chose to remove IBIS because a few videographers complained about sensor vibrations while mounted to vehicles.

I 100% guarantee you the S still wouldn't have IBIS even if the GH5 not had that particular issue.
A lot of people have this misconception that every camera used in high-end production is an Arri or Red that costs as much as a small house. This is false. Movies are often shot (at least partially) with GoPros and DSLRs and cheaper camcorders, especially in a scene where the camera is likely to be damaged or even completely destroyed. Technicolor CineStyle exists because of this need to match the Technicolor film processes with modern DSLR video so that post-processing the final digital image will be easier. A lot of DSLR owners inappropriately use CineStyle because they think it'll make their movies look good but it's not made for that and it looks like crap on their lower-end cameras.

Also, Casey, keep in mind that the same problems which show up in car mount situations will also show up when shooting handheld. Every time a camera operator takes a step on the ground it sends a pulse up their body and into their arms and the camera. Stabilization systems can also wander looking for something to stabilize if they're already super stable in the first place, i.e. on a tripod or gimbal. For info on that, this article demonstrates the problem well: https://photonaturalist.com/when-not-to-use-lens-stabilization/
@PhotoJoseph Now we will have S1 and S1R, and if we see S1S in the market you were right, otherwise Casey's arguments were correct.
PS I own GH5S and love it. Interesting discussion right here.
I appreciate the video and can see the difference. Thank you.

What I don’t understand is why this is win. Would not people who are shooting in cars want stabilization and put them on gimbals? If so would this even matter? Thanks in advance.
IBIS and a gimbal is really not the best way to go always, you can get too floaty of an image.
That so why I am keeping my old G7 despite having the generally superior G9 😄.
I was wondering if you covered triggers anywhere. I am looking at the Pluto, MIOPS or similar triggers for various fun projects like lightening (or me running past...which is just as fast 😂 ha haa), and all the other cool features you can play with on them. It would be good to have a Panasonic focussed review of them.
Excellent Demonstration!
Guess this would apply to running or moving fast paced with a gimbal
PhotoJoseph I've heard someone explain that with the gimbal and a camera with stabilization they've seen more gitter. So after seeing your video the gh5s looks more stable because of its lack of in camera stabilization. I Forgot to mention the gimbal in my first statement
short and sweet! :)
Glad you made this video for those who didn’t understand
