Firmware finally out for GX80/85... will report later, but here it is: http://av.jpn.support.panasonic.com/support/global/cs/dsc/download/fts/index2.html Focus Stacking is now available. New function which enables the user to enlarge focus area after shooting by combining multiple images shot with Post Focus function. [Sequence] can now be selected for Focus Bracket recording. [Flash Mode] can now be set to [Forced Flash Off] for built-in flash. Seems to work as advertised... still testing.

I can understand why you'd want something smaller than the C100. Personally, I'd go GX85 simply because you can practically pocket it with the kit lens. Then just accept the limitations it has... don't want limitations? ... take the C100. Ultimately, you have to decide what you can live with. There are so many (too many?) great choices. For me, the XC10 wasn't even possible because you can't really "start" with it. You simply have it or you don't. Also, I don't need the extra features it offers and the form-factor is too strange and big for me... I might scare my daughter with it.

Agreed... not fair on so many levels. Here's a quick look: Price: $2000 (XC10) vs $800 (GX85) I think the discussion should probably stop there. The form-factors are way different too. The XC10 doesn't look like a hybrid video/photo camera at all IMO- just a video camera. I'm sure it has great ergonomics and I trust @Mattias Burling 's "5 Reasons to buy the XC10." The footage looks nice.

You make some good points and I agree that Panasonic was stupid for the most part in some of their exclusions, but the GX80 is significantly smaller than the G7. The G85 is expected to be even a few millimeters bigger all the way around (128.4 x 89.0 x 74.3 mm). The GX80 is also about 80 grams lighter... just saying because size matters with M43; otherwise, we might all be shooting something different.

Caught Max Yuryev comparing the GX85, Fuji Xt2, 5dIV, and A6300... all of which are the hot cameras right now (especially the A6300 )... a nice video considering low-light, detail, and DR. The GX85 fairs well, especially at its price point.

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.
