Yes when using my S Pro 24-70mm, my S1 and S5 are good enough, even with Open gate on my S1, and yet Open Gate has slower AF. However lenses like the 35mm DG DN f2/f1.4/f1.2 are almost useless. Only the S5II(X) has very fast AF with these lenses, but I can't stand the image quality of this camera.

Yes they use the same processing. The S5 only has the 6K photo mode which is more 5K and cropped, nothing comparable to the Open Gate of the S1 and S1H. On the S5 and S1, I never seen posterization on skin but I mostly shoot below 2000 ISO. Yes HLG on the GH5 was great, even more when using the 5,2K 4:3 Open Gate mode. No oversharpening, detailed but very natural image, more than the recent Panasonic cameras.

Yes, the S5 is still a great camera, AF-C s is pretty bad with most Sigma DG DN lenses though. I prefer the S5 to my S5II, but I like the S1 even more, the 5,9K and Open Gate are crazy good, nicer image quality than the S5II, better detail (like a raw file), no oversharpening and no chroma noise reduction. The image is very similar to the Nikon Z6III 6k raw, but with slightly better IBIS and of course worse AF.

Not really, the S5IIX has no OLPF, in fact even the S1 and S5 have better internal video quality than the S5IIX. Most people can't see the difference, but if you crop a bit in the videos, the difference is not small, especially in 4K and even more when using the 709 profiles.

The lack of new S Pro lenses since 2020 and the fact that they use the same IMX 410 sensor since the S1 in 2019 (a sensor from 2018 introduced with the Sony A7III) is very concerning to say the least. I like my Lumix cameras and lenses but honestly, I really think about switching to Nikon and adapting my FE lenses on a Z6III and Z8.

Interesting test but I own a lot of camera and there is much more to said about image quality. The way the details are altered with noise reduction even at low ISO is also important. To my eyes, my S5II has a very bad rendering in 4K, even more with the standard profiles. Yes 6K and 6K Open Gate are better, but the image still looks more processed than on my S1. And another issue with Open Gate (and even 6K) is the IBIS which is worse (mainly while walking) than in 4K.

I hope not as well, but when I think about their last S Pro lenses, the last one is from 2020 ... The 50mm S Pro and 24-70mm S Pro are among the best lenses I have used, but more than 4 years without S Pro lenses is concerning. I know Sigma released some high end lenses for L mount, but I always prefer the output of the S Pro lenses.

I agree, never had any issue with my GH5 AF when using PL lenses and "1 Area". I can say the same with my GH6 below 48fps.

Yes but this is not true. Undone has always found something to say to fault Panasonic in the past, like he did with the reviews of the 10-25mm saying the 18-35mm had better AF ... And saying the S1 IBIS is much better than the S5 without even comparing them to Sony cameras is doubtful to say the least, especially when he was the first to say the AF was much better on Sony than on panasonic (which was true). Both the S1 and S5 are very comparable for IBIS. The S1 is very slightly better. Even with a 85mm lens, I must really looking closely to see the difference with IS BOOST enabled. An exemple : When walking there is a bit more "jump" on the S5, but the difference is very slight. I used and still use the S1 and S5 a lot and they are really close. I saw some comments saying the S1H had better IBIS than the S1 but I never made a comparison with both so I don't know. The real upgrade was with the S5II, especially when walking, the S5II is noticeably better than the S1 and S5 but it can sometimes look more "digital". By exemple when shooting in 6K or Open Gate with a 85mm and IS BOOST, the S5II seems a bit more stable than the S1, but when cropping I can see a bit more micro jitters on the S5II like if the S5II was applying a stronger correction. This make me think the S5II uses more processing power for the IBIS, and maybe lower the overall image quality compared to the S5 and S1. However when walking, the S5II is clearly better past 24mm, both the S5 and S1 show visibly more "jump". I suppose we can't get a more perfect camera till Panasonic will drastically change the processor and the sensor of their full frame cameras (they still use the same Sony sensor from 2018).

He also said the IBIS in Open Gate and 4k have the same performance, but on his GH7/G9II video he only tested a 8mm lens but even my A7IV has a not so bad IBIS at 16mm. Owning the GH6 and G9II, the difference in IBIS performance is obvious while walking with most lenses.

I agree, even it will maybe harder to make this AI shallow depth of field for videos. But the lenses I like the most are not the ones with the deeper bokeh. I love the Leica 35mm F2 APO Summicron SL or the PL 25-50mm f1.7. Not because of their deep bokeh but because of their rendering, the way how the light convert on the point of focus, the highlights/shadows transitions and contrast. I think it will be harder to mimic the look of some lenses than adding some blur to mimic deep bokeh.

I never use tracking mode on either my S5, S1, GH5 and GH6. I always use 1 area with relatively small square. When using this setting with my GH5 with speed at +5 (sensitivity depends of the lens used), the AF is very fast most of the time, by exemple with the 12-60mm PL or 10-25mm, the focus is sometimes faster and more accurate than my old A7III. The only issue is with low contrast scenes. However even with 1 area, my S5 and S1 have sometimes an hard time to find focus if my subject is moving a lot, even more if the contrast is low or the DOF shallow.

Same here. With better IBIS, I would have pulled the trigger immediatly. The in camera Proresraw, which mean almost zero noise reduction and sharpening along with the 6K 60fps are really tempting.

Yes, I think it's possible, 5,7K needs more processing power. I see the same thing with my S1 and S5II, 4K and C4K are more stable than 5,9K, the difference is pretty noticeable when I walk while recording, 5,9K has more "jumps". Maybe it is why 4K and C4K on the S5II have a so good IBIS compared to the S1 and S5, because the level of details is worse and need less processing power.

But C4K uses the same part of the sensor than 5,7K. And if you look closely, 5,7K is even (very) slightly more croped than C4K. But for 5,8K Open Gate yes it makes sense.
