Hello,
I use Photolab 8.7 to develop Nef files from my new Nikon Z50_2 camera, but when I export jpeg files, the Maker Notes information is not written to the output file. This works normally with all my other SLR cameras and even with my Olympus TG-5 compact camera. Has anyone else encountered the same problem? Thank you in advance for the community’s help.

Can you send one via WeTransfer or similar? There’s a few of us who use Exiftool who can take a look and see what’s happening.
Thanks. A test photo from today Here
Funny, but PL8.7.1/Win JPEG exports include MakerNotes for old Nikon D700 but not for newer Nikon Z8, while for TIFFs they are included in both cases (with ‘Include All’ chosen). Don’t know the logic behind, good catch. Nothing to worry, I guess.
Personally, I strip jpegs of any unrequired metadata, while I keep it all for TIFFs, which serve me as intermediate files. I do look into MakerNotes sometimes, but then I use only NEF files and exiftool or NX Studio to check camera settings or visualize focus point(s).
At first, I thought it was due to “lens ambiguity”.
But the JPEG you provided for download already doesn’t contain any Makernotes.
Do you have a raw file from your cam for us to check?

*I double-checked it with my old D750 and this lens + supported TC and it does provide the maker’s notes.
Thanks for your reply.
Before submitting my question, I ran some tests with my D500 and the same lens, and the Maker Notes are indeed present in the JPEG file. I also tested the Z50_2 with the 2.8/40 macro DX, which has no ambiguity with another lens.
With the Z50_2, the Maker Notes informations are still missing from the JPEG file, but as Wlodek pointed out, are present when exporting to TIFF !
Which is why we asked if you would share the RAW file that you are exporting from, so that we can compare what happens for us.
Maybe if MakerNotes are large enough, say over 64kB, then they are not exported in jpegs to save space? For TIFFs saving few kB does not matter.
Use exiftool -MakerNotes to show the size. It’s over 64kB for Z8 and 16kB for D700.
EDIT: Explanation: According to EXIF specs, all EXIF data in jpegs, including MakerNotes, must fit into a single JPEG APP1 segment, which has a 64 KBytes size limit. This limitation does not apply to TIFFs.
Sorry for my late reply, I had to wait 8 hours before I could post again.

I also ran a test with a Z8 Nef, and the result was the same: no Maker Notes!
@Wlodek: thanks for this suggestion.
I tested it with NxStudio, and it does generate Maker Notes in the jpeg, which are only 3038 bytes in size!
yes, the same here … export to jpg without maker notes as explained by @Wlodek
Yes. For Z8, NX Studio strips some data, most notably the ShotInfo section, which is about 62kB or +95% of makernotes. See Nikon Tags .
Thank you all for your responses.
I’ve managed to get around the problem with a script, but it’s not a permanent solution.
I’ve also submitted a request to DxO support, and I’ve been waiting for their response for three days now…
