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