GH5 GH5 stabilizer: do I have a problem?

Hello, I noticed a very strange thing: yesterday for the first time I removed the Leica 12-60mm and mounted the lens Lumix G Vario 14-140mm. Well I must say that with the lens Leica 12-60mm I have absolutely no stabilization as good as with the Lumix G Vario 14-140mm. Even with higher zoom the Lumix G Vario is much more stable. These buttons are on "On", therefore they are enabled. Why does this happen to me? Even when I film with the wide angle of Leica, I notice that nothing is fluid. Maybe I configured something wrong in the Menu? However the Manual is very bad. The fact is if I will use the Leica less and less for the benefit of the Lumix G Vario. In the Menu of my GH5 I see the "Operating mode" deactivated. Why? Can you help me to configure that Menu? This is what I see in the Menu:

I believe what you are seeing is the Electronic Image Stabilization is off. I am not certain, because you have the language changed, but this is what I believe. Electronic I.S. may seem steady, but it can also cause warping of your video. It's just like using warp stabilizer in Premiere Pro constantly. Uploading a YouTube video of your results with each lense will help us see if the IBIS system isn't performing as expected.

Have you updated the firmware on your camera to the latest?
 
I don't see any problem with those settings. Are you combining them with any other stabilization such as monopod/tripod/gimbal? The 12-60mm PanLeica f2.8-4.0 is the better of my two stabilized lenses. I have seen IBIS cause some problems with my non-stabilized 8-18mm PanLeica at the wide angle settings on a gimbal or tripod, so I switch off stabilization in the menu when using them.

You have everything switched off in the menu which is fine, but IBIS is still working hand in hand with OIS on the 12-60mm PanLeica f2.8-4.0 whenever the lens switch is enabled.

Electronic stabilization whether enabled or not in the menu should not cause warp since it is just using a crop to pan within the frame. IBIS on the other hand can cause warp whether on or off with certain vibrations because the sensor is simply suspended by springs and tilt-able until the field magnets are in play, maybe even then too. I have seen some disturbing jumps and vibrations with my GH5, worse with the 8-18mm non-stabilized. But since the OP's issue is with the 12-60mm, I don't know. It has been the better lens for me.

Another issue is that vibrations or IBIS instability can cause havoc with rolling shutter. This happened on the tripod, where vibrations, possible from wind or touching it set in motion a sustained wobbling of the IBIS sensor or lens OIS that when combined with rolling shutter was a mess of video distortion. That instance was with the 12-60mm, my more reliable lens.

Edit: As I think about this, the last instance I just described was with the GH5s and 12-60, no IBIS so it had to be the lens OIS. And so the other problem I had with the 8-18 was with the GH5 with IBIS on the gimbal, severe "jumps." I remember that IS Lock was on, so that could have been the problem in that instance.

IS Lock has worked really good for me on the GH5 with the 12-60 handheld, even panning, but not on the gimbal or tripod.

IMHO e-stabilization never works on a GH5, ever. It always warps and chunks your image. IBIS alone with manual vintage lenses is quite spectacular and never causes any sort of warp or irregularities that wouldn't be 10 times as noticeable without IBIS. Dual image stabilization with IBIS and a proper OIS lens is simply amazing almost always including on a tripod and either a Steadicam or gimbal.

I would highly recommend that e-stabilization be turned off always and IBIS on always.

Cheers,
Pete

I think the stabilization on Leica 12-60mm doesn't work fine at all for me. What a pity!

You still have to move with a certain level of decency and can't just whip it around and expect miracles. Just because you have IBIS doesn't mean you should shoot like it will always save your butt. You should at least attempt to keep the camera sturdy while walking so the IBIS doesn't have to work as hard.

You are right but I'm sorry you don't understand what I mean. I mean with Lumix G Vario 14-140mm I have a lot more stabilitation than Leica lens, even better with higher focal lengths than Leica lens. Sometimes when I use Lumix G Vario 14-140mm it seems I'm using a tripod.

Maybe your 12-60 is faulty then - my GH5 +12-60 is rock solid esp in IS lock mode.

I tried this tonight on a wedding shoot, e-stabilization off and IBIS on. I did not use the gimbal but did do some handholding with the lens I was noticing with the problem and moving with a tripod. I'm still downloading footage, have not watched it but am hopeful this gets rid of the warping and chunking. I can do some shots with the gimbal later, I'm really curious. I was blaming this problem on IBIS since the lens used didn't include OIS. I didn't think e-stabilization could be a cause because it just pans around the sensor but maybe it can cause warping, but the dread was the chunking and it was on a gimbal which otherwise was running very smoothly. So, more testing but fingers crossed.
