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.

The IBIS of the GH5 is very similar to the GH6, people saying the GH6 is a lot of better never used both cameras (or they are influencers). In 5,7K the IBIS of the GH6 is worse than on the GH5 in 4K, much more "jumps" while walking between 15mm and upward. The real upgrade in IBIS performance is on the G9II (and probably the GH7). However I still get a lot of wooble between 8-12mm on my G9II. The new EIS mode suppress the wooble but also lower the level of fine details because of the crop. About the S9 I'm not sure, I still don't like the S5II internal video engine and I think the S9 has the same. Also the rolling shutter is probably the same than the S5II, though I'm not sure since I have not used the S9. For me the big selling point of the G/GH (outside of IBIS and RS) is the lenses weight and size. Even the tiny 20mm f1.7II has very fast AF on the G9II (though a bit noisy), this combo is a joy to use. And when I want the best quality, it's always with the 25-50mm, I just love how this lens renders (colors and contrast), I think even more than my most expensive FF zoom lenses.

Yes, it's 8 bits ... I think lot of people don't agree, but for me most of time 8 bits files are enough. If I don't need fast AF, 90% of the time I even prefer to use 8 bits 4K H264 files on my S5 instead of H265 10 bits on my S5II.

I agree and most of influencers never speak about these things, they are very enthusiastic about the GH6 4K 120fps or 5,7K 60fps but at no point during their reviews they speak about the drop in detail quality or the lack of Open Gate 60fps compared to the GH5, in the same way they never speak about the drop in IBIS performance when using 5,7K.

I confirm, my GH5 has Open gate 3,3K downsampled 60 fps. Even my GH6 and G9II have not Open Gate 60fps. The GH5 is still the best Panasonic m43 cameras for a lot of things, including detail rendering and Open Gate 60fps.

While the S5II H264/265 uses temporal noise reduction as opposed to the S5 and make the fine details worse especially in 4K/C4K. I think the GH6 being softer than the GH5 in 4K/C4K is mostly due to a more agressive IDP (Intelligent detail processing). In order to reduce moiré, it smooth fine details (making the image more organic for some people) but also reducing the level of fine details when you crop a bit. So if you want to get the same impression of sharpness of the GH5 and tries to add digital sharpening in post on the GH6 (this is rarely a good thing to do but it can help to see the differences of details between different cameras/recording mode by highlighting them), the image becomes very bad with some apparent details looking oversharpened and some very fines details looking smoothed out. The GH5 just keeps more details and even if this camera still use a good amount of sharpening in 4K, this sharpening looks less rough. In 5,7K, the GH6 is much better (and closer than the GH5), fine details looks less rough than 4K/C4K, however the IBIS takes a good hit when walking producing more "jumps". Open gate is very similar to 5,7K on the GH6, maybe the fine details are slightly better when there are not a lot of motion, but the rendering is very similar. However the GH5 in Open Gate is the best I've seen, the level of sharpening is almost the same than a raw picture file, making the image the best you can get on from a Panasonic m43 camera about detail rendering and in my opinion this mode is much better than any mode inside the GH6 or the G9II, even in Prores. Of course I don't speak about DR and colors, for me the GH6 has the best colors of any Panasonic cameras.
