P: Lens profile lost after DNG export

Hello,

I have this issue (re-occurring actually) as well. I am using MFT (Olympus/OM-System and Panasonic) (so I am relying on the baked-in profiles) and after I convert RAW-files to DNG with Adobe DNG-Converter  things are usually perfectly ok. Lately (after the last update of LR?) I realized that the profiles are not properly applied anymore though. On pictures stored in DNG-format LR still shows that it uses the internal profiles (even though the profile is not applied), but doesn't show which one. The original RAW-files the are still working fine. Any idea what I'm doing wrong or what's wrong with the files?

I, too, am having this issue currently. Fuji X-T5 raw files work fine and retain their lens profiles when imported directly to Lightroom, but when converted to DNG using Adobe DNG Converter, they do not. 

Using LR Classic 12.5, Adobe Raw 15.5, and DNG Converter 15.3.0.1451. I'm also using in-camera "Compressed Raw" lossless, if that makes a difference.

Note that LR is showing "Built-in Lens Profile applied," even though it clearly has not (look at the curvature of the fence posts). As often as not, LR will show "Unable to load lens profile."

I can also confirm that files converted using Adobe DNG Converter DO maintain their correct profile settings until they are edited in LR and have had their metadata updated using "Save Metadata to File," or when exported as a new DNG from Lightroom. If a converted DNG file is opened in Photoshop, the correct profile is maintained if the metadata has not been updated with Lightroom. Those lens profiles ARE NOT, however maintained in Lightroom. Basically, if you convert a Fuji raw filed to  DNG, Lightroom isn't recognizing the lens profiles, but the file isn't altered until you save the metadata or export a new DNG.

Hi!

It doesn't seem resolved on my end. It's an intermittent problem which is weird too.  Can you help?

Hi, the problem was solved with one of the next updates last year, after that everything works fine.

Hi there!  I'm having the exact same thing happen.  I'm glad I found this post because I couldn't tell what was really happening.  It's the lens profile that is getting lost when I open up the DNG from LR into PS.  Can you help?  Thanks!

A aparent work around. Select the DNG in file in Library module and go to the menu bar Metadata > read metadata from the file, the distortion correct appears to get corrected but the lens info does not display.

Not something I would be happy with, this need to be attended to ASAP if the integrity of the DNG file function is to be preserved.

The barrel distortion of the DNG has been corrected.

The first screen capture shows the Panasonic profile (and indicates “Camera settings”) did that get applied automatically? Did you export the raw image as a DNG after the lens profile was applied?

The second image ( I presume the DNG) indicates that a built-in lens profile was applied. Very strange. This is evident as the obvious distortion is displayed in the second screen capture.

Is it possible to share a raw image file that shows this problem via Dropbox or similar so other users can check what you are experiencing?

Can't replicate on my Mac, the latest version. Exported a DNG with lens profile as another DNG, imported, the profile was there. Maybe a Windows bug but fine on Mac.
