Not a problem

Lightroom/Camera Raw: Canon RF50mm 1.2 and Canon RF 35mm 1.8 Profile Corrections

Canon RF50mm 1.2 and RF35 1.8 lens don't seem to have profile corrections. I am wanting to remove the vignette on them. I am running the latest version of Lightroom Classic and have the corrections turned on in camera. One user mentioned that the profiles are built into the lenses, but Lightroom just displays the message "Unable to locate a matching profile automatically". Any help would be greatly appreciated!

ALL, and I Mean ALL, Mirrorless cameras have the lens profiles BUILT IN to the RAW file and are Applied Automatically.
In the case of JPGs the lens profile is applied by the camera at the time the JPG file is created.

That sounds great and I hope it is true! I am shooting RAW. But then why do I get this message "unable to locate a matching profile automatically"? How do I apply the correction?

Uncheck the 'Enable Profile Correction' box. The embedded profile is already applied (it is something you cannot turn on or off), so checking this box is the wrong thing to do. It means you want to apply an Adobe created profile and such profile does not exist because it is not needed.

But when unchecked, it isn't correcting the vignetting. See screenshot and note how much vignetting is on the photo I took of a grey card.

Then you'll have to correct this in the Manual tab, for the moment. You can't check the box because there isn't a profile to load.

You can ask Adobe to create a profile, only to correct this vignetting. It's probably best to do this in a new thread, where you explain that you understand why there is no profile (otherwise this whole discussion may get repeated), but then you show why a profile is still needed for this particular lens.

The EOS R does NOT embed the lens profile, so it's incorrect to say that ALL mirrorless cameras have the lens profile built in. Adobe have created lens profiles for some of the RF lenses (the 24-105 for example), so I imagine it's only a question of time before they create a profile for the rest of the RF lens range.
