It sounds like you might be more interested in a dedicated video camera. Honestly, I don't see enough moiré in 4k to warrant any real concerns for the GX80. Yeah, it happens... I've seen it happen on pro cameras too. At the end of the day, most cameras have a frequency where they'll exhibit some sort of moiré. The GX80 is "good enough" for the amount I spent on it... I still have yet to see moiré on the stuff I film. However, I'd like to understand more about what the Venus engine is doing.

Does that include ALL M43 lenses, including the Samyang 12mm F2? I suppose it's hard to know exactly what Panasonic is doing with the Venus engine, but according to sources, it corrects for moiré in software. If that is linked to the lens, I'm not 100% sure. As you say, CA correction is not, but other M43 lenses have a minimum of correction being applied. The question is: in a given scene with moiré, will a Panasonic lens perform better than a non-Panasonic lens?

imaging-resource.com says this: ephotozine.com says this: The previous link was to this picture: You'll notice moiré on her right sleeve... taken with a non-Panasonic lens.

When Panasonic took out the AA filter, their software engineers supposedly made corrections through their jpeg engine for moiré as it was a concern. I read about that in several of the preliminary reviews on the GX80. In one of the reviews (https://www.ephotozine.com/article/panasonic-lumix-gx80-gx85-review-29143/performance) I found an image with moiré problems and it had been taken with an Olympus lens. I'm assuming that the Panasonic software turns on all these corrections for Panasonic lenses and it's not a selective process. For example, I use a Panasonic 15mm Leica lens and its software will compensate for the 6% distortion of that lens (and all of its other problems). However, it won't turn on for other non-Panasonic lenses as there are not any entries in its database for corrections to be made.

I only asked because the GX80 does a lot of corrections (distortion, vignetting, moiré, etc.) with Panasonic lenses but not with other manufacturer's lenses (Olympus, or any manual lens). In this case, it looks as though the frequency hit just right for moiré to happen. If the person backed up 1 meter or came closer by a meter, I bet it wouldn't have happened.

I just wanted to ask you what lens you were using? Was it a Panasonic lens?

That works. I tried it just before this was posted.

Just saw this a few minutes ago... a new firmware for the GX80! https://***URL removed***/news/6015047784/firmware-update-adds-focus-stacking-to-panasonic-lumix-dmc-gx85-gx80 Can't find it yet, but I'll report on it.

You might need to add on top of that a new 4k display, video card, drives, etc. Personally, I'm just going to "rough it" with the GX80 for awhile longer, even after considering some of these cool features in the G80.

Not everyone here has the funds to get the latest and greatest. The GX80's popularity on these forums was due to the incredible value offer it represented IMO...

It's better. The GX80's VF is limited due more to the form-factor- the G80 will be significantly bigger camera than the GX80.

That would be a serious faux-pas. Any way to get confirmation?

I believe it also has a flip-out screen.

I've been trying and liking this recently... I'm just curious what settings were you using for it?

Somehow I missed this review of the GX80's IBIS vs the GX8... interesting.

I'm wondering if this has anything to do with Panasonic not giving a 100% live view in A and S modes like it does in M mode... IMO, this has to do more with contrast-based focus. I'm guessing they will eventually opt for phase and contrast, but I imagine it'll take some time. In video A and S mode, it'll save the ISO setting, but I think it's only saving the ISO at the time of starting the recording... it'll then adjust later in the video if the lighting changes and you didn't lock the ISO with the AE Lock button. IMO it should communicated the ISO upon hitting the AE Lock, but it doesn't.

Well, I imagine many cameras don't display auto ISO levels when recording video in S or A mode; and, you're right they probably should do it. But honestly, S and A modes are foreign to me now in video mode and I think most people are routinely in M mode with ND filters or stepless aperture lenses for minor exposure adjustments. In all the photography-related modes auto ISO is displayed on the GX80.

I have yet to see clips with IBIS on like the first three clips you showed. The floaty one is more like it... not sure what's going on... I don't have a Dual IS capable lens; so, I can't say. The first 3 clips are as if they were filmed on a A6300 with no IS. If you're not getting consistent results with the same settings, I'd say something is wrong. Do more tests and make sure the settings are correct... 4k movie mode, 180 degree shutter speed, etc. Maybe someone else has some ideas...

Agreed... and that's a fair price for that lens too.

I only use the shutter for starting and stopping video in 4k movie mode. I just set up a C mode (that is movie M mode), had the camera set for F4, 1/50, ISO 200, WB, etc.- that's my starting point whenever I film. For photos, I slap in A mode or M mode. I used to have a RX100... could only shoot it reliably in S mode- hated it, but go some nice shots. I would also like this lens, but it's more expensive than the Samyang and it has a ton of distortion (not on video though). I wish there was another option.

An ISO invariant sensor is really cool. Most Canons don't have it; hence blown highlights. Many photographers (including pros) talk about this. Minimum shutters at programmable ISOs is a feature that would be easy to put in a camera nonetheless... maybe next version. Not sure about the new version of the LX100 (supposedly LX15). I think a new lens might be what you need for the GX85 as I think a GX85 (with the 12-32) isn't much of an upgrade when comparing it to the LX100. If I were you, I'd go for something wider than the 30mm; or, are you going to still use the LX100?

I do have another thought regarding the ISO. The GX85 is ISO invariant up to ISO 1600. My recommendation would be to take photos in M at ISO 200 (native ISO) and just shoot away in RAW only mode. Don't chimp the photos because you won't be happy- way too dark. Take them into Lightroom or whatever and adjust your exposure. Shoot like this will mean you have the same amount of noise in your shadows as you would shooting at ISO1600, but you don't blow the highlights. Also, you can just set the SS to your liking in M mode. As long as the conditions don't require anything above ISO 1600, you'll get good results. For someone who cannot do this (i.e.- my wife), I just put into P mode and hope for the best. The GX85's IBIS issue would definitely be floating if anything. Personally, I just try to minimize with technique as much as possible; the rest is left to software if necessary. I sure am happy with taking out the micro-jitters though. The NX1 was/is a great camera- hold on to it because it might have more value one day since camera manufacturers can't seem to replicate its functionality. Again though, the GX85 (with the 12-32) is a much smaller package and not really comparable to the NX1 (with OIS lens). The EM1 mkii could be a winner, but it's competing more with the GH5, which could have even better IBIS/ DUAL IS than the GX85. We'll see. The LX100 is a sleeper video camera though at the wide end. I wouldn't mind picking it up just for that alone. Quirky, yes, but still quite capable. Panasonic/Olypus can't seem to make a cheaper 12mm; really the only option when on a lower budget is the Samyang 12mm F2.0... or you get a used LX100 and you get a even wider and brighter lens with the option of a second body... still thinking this one through.

Sounds like your main beef with the camera is how it/you manage ISO. I really haven't found it that much of a big deal. I just use the ISO button Panasonic gave us. When I'm outside, I just leave at ISO 200 or Auto ISO in Aperture priority mode... shutter always seems high enough for me. Of course, I mainly use the 25mm f1.7 prime. Inside, I just leave in in Auto in Shutter priority or manual. For video, manual is the only option, typically with an ND on it... no need really. For the IBIS, a few people have voiced their frustrations, many are using the 12-32. Have people been having good experiences with that lens? You mention the E-M1... are you shooting in 4k with the Panasonic? I'd think it important to compare apples to apples. The GX85's IBIS is still significantly better than the GX8, GH4, LX100, G7, every canon, every nikon, every pentax, etc. I'm sure they'll only get better. Personally, I'm very happy. No, it's not a gimble, but it takes out my micro jitters which is probably all I want from IBIS anyway.

According to rumors, the update to the G7 and LX100 will be announced around September 19, 2016 and I imagine availability will be in November/December 2016 (in time for X-mas) . I received my GX80 on May 20, 2016. That's a total of 6 months at being the newest. That seems on par with other Panasonic cameras I guess. Actually, I thought the earthquake in Japan would have had an even bigger impact for Panasonic as I believe Sony was making these sensors. Really, the GH5 availability will be the big question.
