Thanks for sharing and don't beat yourself up too much. The only way to really learn new equipment is to use it.

I checked the jittery footage again. It's unusable.
I'm so sorry to hear that, clermond. FCP can't stabilize it enough to be useable?
I'm confused about what is happening there. It almost looks to me like what happens when you have lens IS and IBIS working together without coordination, leading to jittery overcorrections. But the sigma has no IS.
The jitters do not look like handheld shake. It looks like the IBIS is doing it. What do you think is happening? Is the camera reading the wrong focal length and over correcting for it as if it were a telephoto?
Conversely, the 24-105 looks remarkably smooth

I might get some frames out of it. As I had some concerns by reviewing the 1st few clips I did some extra footage later. It's b-roll, no specific scene requested and it might work out.
I have no clue what's happening.
I will dig a bit deeper next week.
And I will also check the same lens on the S1 with the Sigma adapter
update
it could be a firmware issue. Mine has 1.0 and fw has been updated to 2.0 last year.

Sounds like a ‘universal IBIS ON/OFF’ option needs to be one of the things added in a firmware update(should have been there from day one).
On a related note: Ken Rockwell is saying that IBIS in the R5 is not as great as it’s been made out to be. Regarding stills, he’s seeing, at most, about a 1/2 stop improvement.

I call BS just based on seeing what people can accomplish with Canon IBIS vs Sony IBIS
A 1/2 stop improvement on what? Using nothing?

IBIS on/off is available in the menu but only if you attach lens without IBIS
If the lens has OIS the switch on the lens is the universal on/off.
There is no selection of lens and/or body only.
My issue with the Sigma 24-35 might be specific either firmware or incompatibility with the adapter.
I don't care too much about Ken Rockwell, the Northrup couple, Mr. Bloom and other.

He was comparing it to the Canon RP which has no IBIS. Same lens with IS(OIS) on the RP and R5 and he was only seeing about a 1/2 stop better on the R5 with IBIS.

Yes. I understand how it works with the R5. I was was just saying that it should have a universal setting that isn’t lens dependent, so that you can shut off IBIS altogether, period.
Lotsa people don’t like Ken Rockwell and I take him with a(big) grain of salt, but I’ve found over the years that he is generally a straight shooter and doesn’t suck up to any manufacturer and will call something out when others don’t or even the reverse when others may be bashing something

This is how most video/hybrid people are going to see the R5.
Even though we mostly tend to buy multiple bodies, everyone still expects the all-in-one, be the best at everything sort of camera to come along.
Despite what others say though, i really like seeing and learning from everyone here on how to make cameras work. And you and Cleremon have made the R5 work! And not just kinda, but like it seems to be ideal. And that is the “user” part of this community. Making choices based on experience.
I’m not at all into conspiracy theories normally, but the printer one seems rather valid. This doc is worth a watch:
“the light bulb conspiracy “ (about Planned obsolescence, =“dont repair buy a new” - printers are the first examples in the doc, but not the first example in history)

Exactly right. I've had similar problems on the A7RIII with certain Sony E-mount lenses, esp. the 70-200 2.8 G-Master but also the 28-135 4.0 PZ lens. It's like there's a timeout whereby after 10-15 sec of shooting video it cuts power to the lens OIS or IBIS to save batteries. It doesn't happen with Metabones-adapted Canon EF lenses, but that mode uses only OIS not IBIS.
You have to test every lens/body/mode combination well in advance of a real shoot. For cameras with Super35 crop mode that must be also tested for each lens and config, not just full frame mode.

Wow that's a bit nutty - have you told Sony?

I was about to pursue that before coronavirus - I have Sony Pro support. Rather than just call them I planned on first getting together with our other operators and doing tests between a bunch of bodies and lenses, noting lens & body firmware, serial #s, etc. But we've now decided to replace most of our Alpha cameras with A7SIIIs and will probably get a couple of FX6s if they look OK. We likely won't be shooting anything major until early next year so there's no rush. My gut feel is it's a one-off problem since our other operators using the same lenses and bodies have not reported it.
Re stabilization in post, I have many tools for that but in general I think the Resolve stabilizer works the best. It's within the tracker menu of the color panel. Another advantage of the A7SIII is the faster sensor scan and decreased rolling shutter will likely make post stabilization work better. Some of the stabilizers try to correct for jello or rolling shutter but they don't do that well.
