I was told no in camera raw NR was done on the Om1.
But who knows really.
It is so clean, I dont really believe it.
And the image chip of the Om1 is really 80mp. Four sensors under each microlens or something like that. So, you would think it would be more noisy than it is.
No. That's exactly why it's so clean for a small sensor. It's using hardware pixel binning and noise read to do some very cool noise reduction to the raw file with very little deatil loss. Same tech that's in modern phones.
I haven't done any *close to the edge* testing for the sensor of my XH2 or XT5 but from day to day use I think it's the same or *slightly* better than K's OM-1 in normal shooting conditions (exposed properly and not pushed). Your findings do make me interested to see what happens if I need to push the files in *really* low light. It looks like the OM-1 might be better under certain conditions. My Pen F was always a fun camera when the lights went out. Haven't tried the OM-1 like that yet. But I was super impressed when she showed me the first set of files she'd shot in anger after receiving the camera.
A few general points: I don't consider my X2D or GFX great at 6400. I'm sure not going to worry about a smaller sensor at those outputs. Secondly these things can either be fixed in post or generally don't make or break an image anyway.

Anyway, I'm sorry if that image misled the discussion down a different path. The two images below are at correct, default exposure - the second being DPR's test studio scene.
I downloaded the RAW file from DPR as well (ISO12800) and imported it into LR; with a bit of noise reduction the specks disappear.
NR to 50%; Noise Detail to 50%, Noise Contrast to 10%.
(No other settings applied).
Color Noise I cranked way up to near 90% just to get rid of the RGB noise.
If folks are pointing out that your image looks like it has dust on it, maybe you're not doing your NR properly...
Note that this is just Lightroom, not any of the fancy NR tools that are available like Topaz, DXO or ON1.
I'm going to go ahead and bow out of this discussion, as I believe it has largely become circular.
I've spent more time reviewing the images I've shot to-date, making note of the ones which would require extra noise reduction to remove the specks (as compared to the X-T4 and other cameras). I feel that since my primary use-cases for these cameras - the use cases that provide income - are largely unaffected by the issue, I will probably stay the course.
I think it is something Fuji could address with firmware, although I wouldn't want to see that at the expense of detail. For now, if I'm in a mission critical high-iso situation, I have the option of renting from another camera or system.
Thanks to all who engaged in constructive discussion. My 90mm F2 came in yesterday, so I'm off to play! :-)
Glad you found a solution to your issue! I'm not sure that this is a firmware issue, it might just be an inevitability of the hardware. It's not uncommon to see this type of noise in other cameras as well.
I think that the benefits of the higher resolution sensor and better autofocus should outweigh the noise issue you encountered. If not, you can always go back to a lower resolution sensor.
