Greetings.
I have some issue (?) with G85 or lens.
I use it almost year as amateur travel cam and have noticed some sort of lag/jelly/jitter/rolling shutter in my video recordings.
Some raw samples g85_trbl - Google Drive (pls do not judge colors or sharpness)
This is 14-140 II. E-stab iss OFF, in-body stab and lens stab is ON. So this is Dual IS mode.
Lens and body have latest firmwares.
Do i have deffective body/lens?

Hi, I've taken a look at all 3 videos and can't see anything particularly out of the ordinary. They look pretty much like most videos that are shot hand-held without (I am assuming) a steadycam.

P1070200 - I don't see anything, just a slightly uneven vertical panning shot
P1060683 - Maybe a little bit of focus flutter at the beginning and not held 100% steady
P1070290 - The focus is struggling a bit and I guess this one was shot at max zoom as you are struggling to hold the shot steady. This has caused a bit of rolling shutter

I'm really not a video expert, and I'm sure that there are more accomplished videographers that could give better critique. You could try manual focus and supporting/bracing the camera better to help steady the shots out. This is particularly important when using a long zoom, 140mm fully zoomed out is 280mm FF equiv field of view and that's always going to be a handful. Also try to avoid high shutter speeds when panning, this tends to create a tearing effect.

Good luck!

I see it in the Youtube, but I don't see anything like that bad in your videos. I just see hand-held video shake.

You could try turning off either IBIS or OIS if you think that this is a problem and re-test. I'd also try shooting video from a tripod or while bracing the camera against something.

I know that 14-140 II really can have this problems and i bought new 12-60 3.5-5.6 from kit.
But problem still with me: (pls download, not watch in browser)

(easy to see problem on brick wall)
Image not stable and jagging. some sort of horizontal lines lag/jelly/jitter in my video recordings

what can i do? Sell this body and buy new? It have now good price $605 only. Don't know other same price cameras with good video record potential.

Tested at home with artificial lighting .
Actually i don't see that jelly/vibrating.

I checked twice my travel videos for last 2 years (years with G85) and was noticed that problem occurs mostly in sunny good weather. In churches/bad lights camera have big iso (>1600) and less shutter speed and same time I can't find so easily those artifacts.
Check my other raw videos recorded in Italy vacation a week ago in low-light: It's OK and no jitter, right?

Jitters, again! And again:

But when too dark even outside i can't see problems:

I'am start to think i should follow rule shutter speed = fps*2 and buy variable nd filter to keep stable shutter speed? But i though it was only recommendation for smooth motion, not use-or-gtfo rule to use it on cameras. Seems i was wrong.

For some reason I can't view the videos, but from the comments here I am wondering if this is a simple matter of not being stable while holding the camera. Do you have your elbows out like the wings of a bird or is your left arm held tightly against your body? Left hand again, are you supporting the camera solidly so your right hand could be removed? Are you leaning or bracing yourself against solid objects wherever possible?

My view is maybe a little unusual but I don't think there is such a thing as a camera that is too stable. I work like crazy to stabilize my camera hold, then I take whatever in-camera stabilization gives me as a gift. I absolutely do not rely on the camera to compensate for a sloppy hold, popular though that seems to be.

Though he did state that he had O.I.S. turned on the lens (least the 14-140), and the 12-60 I assume has OIS as well yet doesn't exhibit the same problem.

If the problem is due to weak holding, it will appear to be random and uncorrelated with anything except how the OP handles the camera from shot to shot.

I'm also going off the consumption that he's been obsessing over this a bit, and would be producing consistent results trying both lens back and forth. Handling shouldn't be that drastic between the 12-60 and 14-140.

Sorry I did not make my point clearly. What I am calling "handling" changes with the circumstances; standing freely, braced against a wall, windy/not windy, sitting, ... The camera and lens are pretty much irrelevant to camera physical stability until you get to some pretty big lenses like the 100-400.
