Corrupted photo metadata (EXIF) under iOS 26.7 except iPhones

My final summary: fortunately the update to iOS / iPadOS / MacOS 27.0.1 resolves the described issues and works fine for the jpg files exported from Lightroom Mobile as well. Thanks again for your feedbacks.

Finally I have exported the same photos with Lightroom online (Lightroom web portal) and imported them to the photos app. This works actually fine, all metadata are there and correct. So apologies to Apple, I have to address the issue to the Lightroom Mobile team at Abobe instead.

Thanks to both of you for your valuable feedbacks.

I tested those images in macOS 27.0.1 and iOS 16.7.16 (saved to Photos from Fils.app yes it is old...) and both devices identically display these tags:

Canon EOS M100

EF-M11-22 ƒ4-5.6 IS STM

ISO 200, 17 mm, 0 ev, ∫5, 1/50 s

Most tags are the same but are some differences. Have you enabled all metadata when exporting from Lightroom?

exiftool -diff can display all possible differences:

Could you post the original out of camera .jpg and the Lightroom-exported .jpg on some cloud service so we can take a look?

Yes, the EXIF information is fully available for the photos and I can see it in the file browser under „information“.

In the meantime, I have done a countercheck with jpg files directly out of camera and imported to the photos app. No issue in this case, the EXIF metadata are correctly displayed in the photos app. The issue comes up with jpg files exported from the Lightroom mobile app. Again, all metadata information available in the file browser, but the information gets corrupted once the photos are imported to the photos app.

I might try later how iPadOS 27 Photos displays those images when I can upgrade its OS.

I just upgraded to 26.7.1 on my iPad, and I don't see any problems with Photos metadata. My Nikon and iPhone data are intact. Old Canon cameras' data seems OK. Have you looked at the Exif data directly?

Please find below the links to

a) jpg out of camera: https://drive.google.com/file/d/11vs0r6hOqJL2zKEsEi8KpSBdj_72LpGj/view?usp=drivesdk

b) jpg export from Lightroom mobile: https://drive.google.com/file/d/1Ny327ka_9RQQp4gdIUNj6m5Jr9xBhGSA/view?usp=drivesdk

Note: jpg out of camera under a) directly imported to the photos app correctly displays camera „Canon M100“, lens „EF-M 11-22mm f4-5.6 IS STM“, ISO „200“, focal length „17mm“, 0 ev, f „5“ and exposure time „1/50 s“.

The data for jpg under b) get corrupted once imported to the photos app as explained in my first post (e.g. no camera information, focal length „258.99 mm“, f „259“, exposure time „259 s“).

Yes, I have enabled all metadata when exporting from the Lightroom mobile app. So, it seems still unclear why the photos app converts the metadata for case b) in such weird values like f-stop 259 or emtpy fields for camera and lens model.

Moreover, everything worked fine when looking on older photos from August 2026 and earlier in the photos app …

Thanks for the update. For some reason both images you attached here displayed metadata OK on my Photos macOS, iOS, and iCloud setups. Go figure.
