Lightroom can find a lens profile for my Google phone but not for my Panasonic DMC-TZ60. When I 'enable profile corrections', LR says "unable to locate a matching profile automatically". When I check the list of available makes neither Panasonic nor Leica (its lens) appear on the list. I have lived with this for years and will presumably not come to harm if it's not fixed, but I'd love to know what's wrong !!
 
Does it perhaps say at the bottom that an embedded profile has already been applied? In that case there is no separate profile.
 
Thanks Johan.

No, not for JPGs.

But I now see that for RAW images if I click "enable profile corrections" it says "built in" for the make, and below says "built-in lens profile applied". But there's no change to the image (I looked carefully) that might have indicated a profile being applied. Is that as expected?

So why no profile for JPGs? Is there somewhere in LR I can look to see what profiles exist?

Of course....the profile is applied during the raw conversion, so you only ever see the corrected image. Checking/unchecking the "Enable profile corrections" thus has no discernible effect as you can only ever see the corrected image in Lightroom.

The vast majority of lens profiles developed by Adobe are for raw images only, the working assumption being that SOOC jpegs will already have been corrected in camera (and that would certainly have been done so in the case of built-in lens corrections).
 
Thanks Jim, ok. So what is the function of the "enable profile corrections" checkbox on each raw image? Mine seem to be unchecked by default.

It was my Pixel 2 phone that made me curious: LR clearly has a specific lens profile for its JPGs. When clicking to apply the profile, I see small distortions / movements in areas of the picture. If the Panasonic can self-correct JPGs, I'm very surprised that Google does not do the same.

This means that the raw file contains an embedded profile, that is always applied by Lightroom. That is why there is no separate profile needed in Lightroom and why ‘Enable Profile Corrections’ does not do anything.

Jpegs from the camera obviously have this profile already applied as well. The camera software has already done that, so that is why there is no profile for jpegs either.
