V-LOG is very bad for Autofocus. You should try HLG (almost the same DR) or even CINE-V, the AF is better than with V-LOG. Also, the more DOF you get the better is the AF so it is not very surprising than lenses like the 24mm or the 20-60mm (on the wide angle) perform better than lenses longer than 30mm.

Undone is the guy who claims the Sigma 18-35mm has better AF than the Summilux 10-25mm on the GH5. I recall he also said the A7SIII 4k video was sharper than the A7III. He clearly biased for Sony and destroys anything about Panasonic. About his S5 review, the only thing he said about the IBIS was the S1 is clearly better without comparing to Sony or anything like that.

You noticed the IBIS is less effective in 6K open gate or 5,9K ? The IBIS in 5,9K is fantastic. So good you can simulate slider shots in post.

I can't agree more, especially for the S1/S5 and the NX1. I still love to use my NX1 in good light at base ISO, colors and sharpness are outstanding with the 16-50mm S. The S1/S5 are also great, image quality is IMO superior to the Sony A7SIII. I like to use the S1 6K mode combined with the wonderful IBIS and the 50mm S PRO to shoot dolly like footage with awesome quality.

I only use 4K because I watch my videos on a big TV. I downloaded some clips with 20 and 100mbits in 1080P but I don't see a major improvement. I also compared some of my old 4K videos with my GH4 and the GX9 is really worse noise wise. I think it's a pretty bad idea from Panasonic to use such a crop on a 20MP M43 sensor.

I have a GX9 but the 4K mode is disapointing to say the least. I can live with the 1.25x cropping, however because of this crop, the noise is everywhere, even at ISO 200. It could be awesome if it was possible to remove the crop in 4K. This little camera is almost perfect otherwise for daily use , pocketable with small lenses, good IBIS, nice colors etc.

Very nice pictures.

Sadly, S5 is limited to 5K internal, this is the "6K" photo mode but the resolution is "only" 5184x3456 with no way to use things "like IBIS Boost". Only the S1 can do 6K and 5,9K internal.

I prefer to get 5,9K and 6K open gate than 4k oversampled to 7k. Furthermore, I don't know about the A7IV but the A7III and A7SIII have massive noise reduction, I think the A7IV will have the same. The IBIS on Sony is almost useless, it depend if you use your camera for run and gun, but the S5/S1/S1H are miles ahead for stabilization. About LOG, Panasonic has VLOG, DR and colors are top-notch

I love Panasonic, I have the GH5, S5 and S1 with very good lenses. The S Pro lenses are magnificent and the S5/S1 image quality is great. However The AF is just bad, even with the firmware updates. Even the old NX1 is faster in video.

I watched two reviews from him. The Panasonic Leica 10-25mm and the Sony A7SIII. On the first video, he said the Sigma 18-35mm with SB had faster AF than the 10-25mm. On the second video, he said the 4K of the A7SIII was sharper than the A7III. Why not ...

Yes, my mistake. Thank you for pointing that out, I never used the Pocket 4K. I thought it was the same process.

I remember Andrew and a german site said DCI 4K was slighlty softer than UHD on the NX1 (and GH5) because the size of the sensor used on DCI 4K was a bit smaller than UHD. However, the rolling shutter must be a tiny bit better on the DCI 4K, again because of the size of the sensor used with DCI 4K.

Great pictures, Pana Leica 50-200mm ?

I used the A7SIII, the S5 and the S1. I returned the SIII because of the noise reduction, colors, IBIS, MP and sharpness. I don't need the 120fps 4K 1.1x and the fast AF-C. My S1 and S5 with the S Pro 2.8 have very fast AF and good enough AF-C. And even if Sony has more lenses I prefer the Lumix ones. I had/have the 24-70mm GM, 70-200mm GM and 50mm Zeiss Sony 1.4, the Lumix Pro equivalent lenses are better (sharpness, bokeh and 3D pop). About the S5, it's a great camera, but the S1 is even better (slightly better IBIS, better EVF, 6K internal next year etc ...) !

I agree, I had the A7III and noise reduction was very strong. I tried the A7SIII one month ago and even if the image is cleaner, there is still a lot of noise reduction. My S5 and S1 keep more details (although noisier).

I love the S5 as well. Coming from Sony FF , it's nice to have good IBIS and to get ride of the ugly noise reduction at high ISO. And the 50mm PRO is the best 50mm lens I have ever owned (even better than Sony Zeiss Planar).

There is advantages and disadvantages on both cameras (the S5 will get the 5.9k raw update too), in the end it's about user preference. As an hybrid shooter, I much prefer the S5.

No doubt about the better image, better IBIS too.

Slightly less good dynamic range than S1H and S1. https://www.cined.com/panasonic-lumix-s5-lab-test-rolling-shutter-dynamic-range-and-latitude/

Luckily for Sony, they have some popular Youtubers with biased reviews.

Interesting test about the R5/R6/A7SIII/S5 dynamic range ... https://www.slashcam.de/artikel/Test/Der-Dynamikumfang-von-Canon-EOS-R5---R6--Panasonic-S5-und-Sony-A7SIII-im-Vergleich--Erkenntnisse---Fazit.html#Fazit

Yes we must wait for Andrew's review.
