Canon EOS R6 mark 2 raw files noisy and grainy.

(fyi-I have open this new discussion as a reference point)

Seems like I am having the same issue with the grainy photos, I shoot in raw, for wildlife (birds) in flight I shoot manual, auto ISO with shutter speed above 1200 for eagles, ducks and 5000 for hummingbirds. The shots look clear and clean when taking them and even after in the camera but when downloaded to my PC, it shows as below, even after processing in lightroom, it still does not look as sharp as should be.

Using Canon EOS R6 mk2 with Sigma 150mm - 600mm contemporary glass.

 Not sure why the raw is so grainy, anyone having the same issue?

Yes, I think you hit the nail on the head, my shutter was a bit to high.

Much appreciated.

[Terry_R6mk2]

I think that you are right, I will test it again.

much appreciated.

I have the same lens and same issue

I lowered my auto ISO in the menu and took more shots, they were much better but Canon need to fix that thing about what we see it clean and sharp in the camera review as to what comes out on the computer which has a measure of blur.

Start a new thread and share some raw files.

Your ISO is too high, it may be 'OK' for a subject tight in the frame on a brighter day, but the noise is too much. 

A lot of photos may look better on the camera screen than they will on the bigger computer screen.  Zoom in on your review and it may not look so good.  Many photos look good on the camera screen, that's why so many phone photos look great on the phone.
