Question: How to preserve Lens data (manufacturer / type)

Question: If I export raw files to jpg using PL 3.1, the lens data (manufacturer and model) is lost. Is there an option to preserve the data?

Exiftool output with LR export:

Exiftool output with PL export:

EDIT:
Exiftool also claims “invalid metadata”:
exiftool_inv_meta

It should not get lost. I am on a Mac and in the export window there is a box called “Remove Exif data”
make sure that this is not ticked

No, the option to remove metadata was not activated. As you can see above, there is metadata, but incomplete.

Is the lens data showing correctly in PhotoLab’s Metadata palette before you export to JPEG?

I have a similar problem with Color Efex Pro 4 stripping the lens info from EXIF. When it saves a TIFF file and I view that in PhotoLab, that info is no longer visible in the Metadata palette or in any further exports. I have a support ticket open, but it hasn’t been updated since September.

Will check that tonight.

What I get on my Mac: Both Lightroom and PhotoLab exports contain lens data. I also see that different exif readers present lens data differently, so I checked with a hex editor, searching for EF24-105 or similar expressions. Here is what I get:

  • Output from PL contains one entry
  • Lightroom output has three entries (the screenshot only shows the first entry)
  • Positions in the files differ too

My conclusion is, that PL writes lens data, but maybe in a position that is not checked by all the apps out there. It would be nice if DxO could make their output more robust (same for all the others out there) :grimacing:
