Lumix S1Rii - Raw Files - High Shadow Noise

I was watching a Lumix S1Rii YouTube review from "Jan Bors Creative" and he mentioned that he allowed free downloads of his Lumix S1Rii Raw files at his "Buy Me a Coffee" link

After downloading and looking at the files in Lightroom, I am noticing very high noise when bringing up the shadows, even at low ISO settings. I also processed and exported the RAW files to 4000x6000 pixel JPEGs to match my Lumix S5 resolution. Even with the downsizing from Lightroom, the noise is much higher than in my native S5 files.

I don't use these cameras for video, just photography. I was hoping that this 44.3MP full-frame sensor could almost match the resolution and beat the noise from the older GFX 50 cameras.

I think that Panasonic when trying to make this a robust video camera, and a high FPS photo camera, has made noise concessions for still photography. For now I will keep my S5 and if I need a higher resolution image, upsize the RAW with Lightroom's Super Resolution mode, which works excellently on the clean RAW files from the original S5.

I was also watching another Lumix S1Rii YouTube review (and comparison to Sony A7RV and Canon R5II) from "Manny Ortiz" where at the 8:00 minute mark he mentions similar finding with artifacts in the files when bringing up the shadows.

After watching this follow-up video, it seems that Lightroom's support for the S1Rii files may be premature. Better results are found in Capture 1 when bringing up the shadows:

That figures. I remember when the S5ii first came out, DxO Photolab made a mess of lifting shadows. They fixed it pretty rapidly.
 
Yeah, I also got my hands on some raw files (courtesy Richard) from the S1RII and ran them through Cap1, and I thought the outcome looked pretty good. IIRC Richard's big S1RII video does some direct comparisons to the 24 MP sensor, and while the lower-res sensor did have an edge in shadow recovery, it wasn't very large (he used C1).

Interesting. I had downloaded all the RAWs from the DPreview review. And I looked at these in Lightroom, and pulled all of the shadows up to 100% and did not see anything troublesome. One exception, there is one picture of Tokyo at night with a large region of completely dark sky, and it showed more noise than I'd like (at ISO 640). I ran Lightroom's noise function on that and it completely cured it. Note that I always process in the HDR mode and typically have already lifted the exposure 1 to 2 times before increasing shadows. For that picture in question it was lifted +1.25.

Anyway, thanks, I'll look at this some more.

I did download and try Capture One. There is quite a difference from Lightroom with S1R II RAWs, and that photo with Tokyo night sky at ISO 640 has no noise. There is another DPreview photo with the Tokyo night sky at ISO 6400, and that night sky also has no noise, and the features in the shadows only have fine grain noise. (To be fair, Capture One does clip the blacks, and maybe I should clip blacks with Lightroom for this case.)

I had held off getting Capture One because the S1R II comes with a free three month trial. But Capture One has a one month free trial for anyone, and I got that for now. I must say all the DPreview RAWS are beautiful with Capture One; they have done a very good job with the RAW converter. They also have RAW conversion for the Hi Res RAWs, where the early version of the Lightroom conversion doesn't have this yet. I'm hopeful the Lightroom RAW converter will improve and get up to par with Capture One, because Lightroom is my main photo editor. Or else $$$ :(

Yeah, I've never liked C1's interface, but I have to admit they do a better job of RAW development on some tough files than On1 does.
 
This kind of early cock-up could sink quite a few potential sales for Panasonic.
 
Hmm. I can only assume that C1 is doing some NR behind the scenes without making it explicit. I can't see how LR can be creating noise.

That Leica SL3 is looking more interesting for photographers ! Pity it's $$$$ and that the rear screen is tilt only.
