Unable to save profile correction changes with RAWs that contain embedded profiles

[Rukes]

Lightroom 14.1.1 on macOS 15.3, MacBook Pro M4 Max

Using a Canon R5MkII with a Canon RF 24mm F1.4 VCM lens which comes with forced profile correction in the RAW based on how the lens is built.

Bug: Currently if you load a RAW image, it does not load the Adobe Camera RAW profile for the lens:

Model - Canon RF 24mm F1.4 L VCM

Profile - Adobe (Canon RF 24mm F1.4 L VCM)

but instead defaults to the built-in correction:

Model - RF24mm F1.4 L VCM

Profile - Camera Settings

This profile is unable to be modified and saved with any new default changes, i.e. changing the Vignetting, then going to Save Lens Profile As Default, will NOT save the changes as designed.

Optimal situation: Allow the user to save any lens profile corrections for lenses with embedded profiles for future use, or allow the user to select the Adobe Camera RAW version of the lens correction profile as the default for the lens.

Steps:

1. Edit a RAW file, change the Vingetting setting to 50, and click Setup: Save New Lens Profile Defaults.

2. Edit a second RAW with the same lens, and in Lens Corrections, change Setup to Default (if it's not already). Observe that Distortion and Vignetting are 100 (incorrect).

3. Select the Adobe Camera RAW profile for the lens, edit Vignette to 50 and Save New Lens Profile Defaults.

4. Open another RAW file, immediately change the profile from the Embedded to the Adobe one. The correct settings will have been applied, but both Vignetting and Distortion will still be shown as 100. Only after moving the slider bar slightly will either immediately jump to the near 100 setting, showing the profile did save the new defaults but something is showing it incorrectly on top of it.

Lightroom 14.1.1 on macOS 15.3, MacBook Pro M4 Max

Recently bought the Canon RF 24mm F1.4 L VCM lens for my Canon R5MkII body

Upon importing RAW images to Lightroom, it loads up this camera profile:

Make - Canon

Model - RF24mm F1.4 L VCM

Profile - Camera Settings

For some reason this profile being loaded is giving me issues customizing the default lens profile settings for this lens. I can't save adjusted settings as a universal default for this lens. 

If I go to model, I can find the proper profile:

Make - Canon

Model - Canon RF 24mm F1.4 L VCM

Profile - Adobe (Canon RF 24mm F1.4 L VCM)

How do I make this lens load up this second profile by default and not the odd "Camera Settings" profile.

All my other lenses properly load the Adobe profile for their lens, it just this specific lens seems to only load the Camera setting one.

To change the default lens profile, select it and then choose 'Save as new Lens Profile Default' from the Settings pop-up menu in the Lens Corrections panel.

[Rukes]

That does not work for this lens, unfortunately. 

I load up the RAW file, it loads

Make - Canon

Model - RF24mm F1.4 L VCM

Profile - Camera Settings

I change the vingetting and save as new lens profile default. Closing and restarting lightroom and importing the same RAW or a different RAW with the same lens will still load the same profile as above but with zero changes.

Profile - Camera Settings

By @Rukes

That means that this profile is embedded by the camera. In that case I do not think you can change it with a new Lens Profile default. What you can try is change the settings in the Lens Corrections panel, and save that as a Develop Preset. Then apply this preset on import. 

[Rukes]

Is there a way to apply a preset on import for a specific lens? Seems I can only do it to every file unfortunately and if I have multiple lenses, it would apply the same vignette setting to every different lens. 

[JohanElzenga]

No, if you apply a preset on import, then you apply it to all imported images. What you can do is first import all images, then select the images with this lens (use the filter bar), and then apply this preset to the filtered images.

[richardplondon]

Two settings apply for user-customised lens profile detection:

On a sample image, you need to select that different lens profile and then save this as 'New (user) Default Profile'

But also: when lens profile selection shows "Auto", images will ignore that. They need to show 'Default' instead.

All that said, some images report no - or at least, non-unique - lens information thus neither Auto nor Default can ever give appropriately varying result per lens. As an example: many older manual lenses report just their 'general class of lens' to Lightroom. My Pentax camera prompts me to manually enter a focal length when mounting a non-recognised lens (for purposes of in-body shake reduction) and this focal length info makes it into the image metadata. So that taken together with the 'general class of lens' info, helps me batch-apply a Develop preset which imposes the appropriate profile as a Manual selection.

The same issue arises when different lens models electronically report the identical lens ID code to the camera. When both are by the same maker this will never happen AFAIK, but it can do otherwise. 

[Rukes]

Unfortunately that does not work with this lens. 

Loading it up it brings up the Camera Settings strange profile. Any defaut changes that are saved do not carry over.

if I change it to the proper Adobe profile, any changes that are saved are still not saved as default for this lens profile.

Subsequently reloading new RAW images with the same lens medatada, it will load up the Camera Settings profile and even manually changing to the Adobe profile with the saved default changes, will still load up the default values and NOT the new saved default profile.

Loading up the RAW images I did change the default profile on WILL load up the proper Adobe profile with the correct changes, but ONLY for that specific file. It seems for some reason profile changes with that lens profile just apply per image and not by the lens metatdata.

Thanks for update - I do agree camera embedded corrections should be possible to negate (and then substitute) but perhaps Adobe does not have a completely free hand contractually?

[GoldingD]

Can you take a photo with that lens on that camera. A photo that you do not mind sharing,. And upload it to a share (DropBox, etc) so that other members can test.

@GoldingD: "Can you take a photo with that lens on that camera."

You can download a sample raw with that camera and lens from dpreview.com:

Thank you, and I see the authors problem (but not the solution) using this sample.

Building on Johan's reply, Save New Lens Profile Defaults doesn't work with lens profiles that are embedded in the raw by the camera (which show up as Profile: Camera Settings in the Lens Corrections panel).  A bug report was filed about this last fall, but Adobe has never acknowledged the bug or marked the behavior "as-designed":

https://community.adobe.com/t5/lightroom-classic-discussions/error-when-saving-changed-profile-corre...

It's hard to know what the "as-designed" behavior should be, since Adobe has never updated the documentation about lens corrections after LR 9.4 allowed embedded lens profiles that the user could disable:

Thanks for that! Created a new post in bugs with refrences to that post and this one, hopefully Adobe sees it:
