P: Denoise AI and Pentax K3 MKIII DNG files - not working

With my K-3 Original the Denoise AI works perfectly.

With my new K-3 Mark III the Denoise AI has little to no affect. I am greatly disappointed as this is one of those features that got me to move from Luminar to Adobe. 

Any progress with figuring out what is causing this bug and when there will be a fix released?

I have the same problem with my K-3III - that is, very little to no noise reduction, with patchiness in the application. I've even seen noise reduction in lighter areas while there is next to nothing in the darker areas - weird.

My old K-3 files shot at 51,200iso however can be noise reduced totally and completely.

Thus I concur with thix2112.

Agree that K3 mark iii (ISO 12800) sample showed practically no difference between the original and the LR Denoise version.

Can confirm that LR Denoise works well K-3 mark i (ISO 6400) and K-5 (ISO 51200).

LR Denoise also works on K-1 mark ii (ISO 16000), which is odd, since the mark ii was an upgrade from K-1 mark i (Co-Processor chip on the motherboard that significantly reduces noise at high ISO)

Seems to work with K1ii files ok. I did not extensively test it, but seems to work. I also have a K3 original but haven't been using it since my K3iii. So I don't know if Denoise works on K3i files

Funny enough, I ran some RAW DNG files out of my old Pentax K30 and the Denoise feature worked like a charm in both Camera Raw and LR. Seems like this bug is only affecting newer Pentax camera RAW DNG files. Weird. 

I was just about to start a thread on this very same topic, but found yours. I too see almost no difference in my raw, high ISO (3200 and above) DNG files coming out of my K3iii when processed through the new Denoise feature in either Camera Raw or LR, Thought it was just me, but apparently not. Would be cool if they got on this. 

I try to use denoise to my foto (pentax k3 iii) en does'nt work

can you tell me the reason?

thanks

Ricoh cameras are experiencing the same issue but we have separate bugs filed for them. Ricoh here: https://community.adobe.com/t5/lightroom-classic-discussions/lr-classic-12-3-denoise-dont-work-for-raw-files-from-ricoh-griiix/td-p/13736622

Only the color noise is being affected by Denoise. 

There was another forum post with a similar (?) camera that had the same issue. 

Rikk - it seems to be ineffective on all Pentax K-3 mark iii DNG files as a general rule. This discussison started over on the Pentax Forms discussion group. I confirmed to the group and the group concurs that Denoise AI appeares to be ineffective on K3iii DNGs.  

Thanks for your attention on this.
