The R5...I still think is noiser than my 5D IV when it comes to needing to pull detail from shadows in low light, but at least the rings/swirls are sorted out.

The R5 is much less noisy than 5DIV, if you shoot in the game conditions and settings. I had 5DIV and can compare.

If your R5's images are noisy, there's something wrong with either the camera, or settings, or workflow.

Check if you have something like highlight tone priority or electronic shutter enabled (don't use electronic shutter at ISOs less than 800).

Thanks everyone!

I have the exact same problem with my two Canon R3 cameras. I shoot a lot in low light conditions and often at ISO 25,600, which is the highest ISO that I can get away with before the pictures are completely unusable.I use Lightroom Classic to edit my photos and have tens of thousands (maybe hundreds of thousands) of phtos organized in one Lightroom Classic catalog. As a member of the press, I need to occasionally search for and use old photos, so I really cannot switch where I catalog my images.

I have been hiding the swirls by using the Topaz AI plug-in when I am editing in Lightroom Classic. That gets rid of the swirls but the resulting images are muddy and barely usable without extensive tweaking.

It sounds like Paul was able to get rid of the swirls by changing editing software, but it sounds like you are blaming using electronic shutter mode when shooting at high ISO. I use electronic shutter mode exclusively with my two R3 cameras, no matter what the ISO. I thought that the only potential problem with using electron shutter was a "rolling shutter" effect, which I have not seen in my photos. Is this another problem with using electronic shutter?

I had switched from 50 years of shooting with Nikon DSLRs to switch to the Canon R3, because I shoot a lot of professional auto racing. The R3 has great race car autofocus. I had sold all of my Nikon gear, so switching back to Nikon was not possible.

Please advise. Thank you.
